How do screw jacks handle challenges like load imbalance or uneven surfaces?
Screw jacks are designed to handle challenges such as load imbalance or uneven surfaces through various mechanisms and features. Here’s how screw jacks address these challenges:
- Load Imbalance: Screw jacks can handle load imbalance by distributing the load evenly across multiple screw jacks. In applications where there is a significant load imbalance, multiple screw jacks can be used in a synchronized system. The synchronization ensures that each screw jack shares the load proportionally, preventing excessive stress on any individual screw jack.
- Self-Locking: Screw jacks have a self-locking feature that allows them to hold their position without the need for continuous power or external braking mechanisms. This self-locking capability helps maintain stability and prevents the load from shifting even in the absence of power or during power loss.
- Anti-Backlash Mechanism: To handle challenges related to backlash or unwanted movement caused by load imbalance or vibration, some screw jacks are equipped with anti-backlash mechanisms. These mechanisms minimize or eliminate the clearance between the screw and the nut, reducing the potential for backlash and ensuring precise positioning and stability.
- Flexible Mounting Options: Screw jacks offer flexible mounting options, which allow for proper alignment and compensation on uneven surfaces. Mounting brackets or couplings can be used to adapt the screw jacks to different orientations or to compensate for variations in the mounting surface. This flexibility ensures that the screw jacks can be securely installed and adjusted to accommodate uneven surfaces.
- Guidance Systems: In some cases, screw jacks may incorporate guidance systems to improve stability and alignment. These guidance systems can include linear guides or rails that guide the movement of the screw, ensuring smooth and accurate operation even when dealing with load imbalance or uneven surfaces.
By employing these mechanisms and features, screw jacks can effectively handle challenges related to load imbalance or uneven surfaces. They provide stability, precise positioning, and the ability to distribute loads evenly, making them suitable for a wide range of applications even in demanding environments.

Can you explain the basic principle behind the operation of a screw jack?
The basic principle behind the operation of a screw jack is the conversion of rotational motion into linear motion. A screw jack consists of a threaded shaft, known as the screw, and a nut that engages with the screw’s threads. When the screw is rotated, it moves the nut linearly along its threads, resulting in linear displacement. Here are some key points regarding the basic principle of operation for a screw jack:
- Rotational Motion: The operation of a screw jack begins with the application of rotational motion to the screw. This can be achieved through various means, such as manually turning a handle, using an electric motor, or employing hydraulic or pneumatic systems. The rotational motion is typically applied to the top end of the screw.
- Threaded Shaft: The screw in a screw jack is a threaded shaft with helical grooves running along its length. The threads can be either square or trapezoidal in shape. The pitch of the screw refers to the distance traveled along the screw’s axis for each complete revolution. The pitch determines the linear displacement achieved per rotation.
- Nut Engagement: The nut is a component that engages with the screw’s threads. It is typically a cylindrical or rectangular block with a threaded hole that matches the screw’s threads. The nut is free to move linearly along the screw’s length when the screw is rotated.
- Linear Motion: As the screw is rotated, the nut moves along the screw’s threads, causing linear displacement. The direction and magnitude of the displacement depend on the rotational direction and the pitch of the screw. Clockwise rotation typically results in upward linear displacement, while counterclockwise rotation leads to downward displacement.
- Mechanical Advantage: One of the advantages of a screw jack is its ability to provide a mechanical advantage. The pitch of the screw determines the distance traveled per revolution. By increasing the pitch or using multiple-start threads, the linear displacement achieved per rotation can be increased, allowing for the lifting or lowering of heavier loads with relatively less rotational effort.
- Self-Locking: The friction between the screw and the nut helps to maintain the position of the load once the rotational force is removed. This self-locking characteristic of screw jacks allows them to hold loads in position without requiring continuous power or external braking mechanisms.
In summary, the basic principle behind the operation of a screw jack involves the conversion of rotational motion into linear motion. By rotating the screw, the nut moves along the screw’s threads, resulting in linear displacement. The pitch of the screw determines the distance traveled per revolution, and the self-locking nature of the screw and nut interface helps maintain the position of the load.

Screw Sizes and Their Uses
Screws have different sizes and features. This article will discuss screw sizes and their uses. There are two main types: right-handed and left-handed screw shafts. Each screw features a point that drills into the object. Flat tipped screws, on the other hand, need a pre-drilled hole. These screw sizes are determined by the major and minor diameters. To determine which size of screw you need, measure the diameter of the hole and the screw bolt’s thread depth.
The major diameter of a screw shaft
The major diameter of a screw shaft is the distance from the outer edge of the thread on one side to the tip of the other. The minor diameter is the inner smooth part of the screw shaft. The major diameter of a screw is typically between two and sixteen inches. A screw with a pointy tip has a smaller major diameter than one without. In addition, a screw with a larger major diameter will have a wider head and drive.
The thread of a screw is usually characterized by its pitch and angle of engagement. The pitch is the angle formed by the helix of a thread, while the crest forms the surface of the thread corresponding to the major diameter of the screw. The pitch angle is the angle between the gear axis and the pitch surface. Screws without self-locking threads have multiple starts, or helical threads.
The pitch is a crucial component of a screw’s threading system. Pitch is the distance from a given thread point to the corresponding point of the next thread on the same shaft. The pitch line is one element of pitch diameter. The pitch line, or lead, is a crucial dimension for the thread of a screw, as it controls the amount of thread that will advance during a single turn.
The pitch diameter of a screw shaft
When choosing the appropriate screw, it is important to know its pitch diameter and pitch line. The pitch line designates the distance between adjacent thread sides. The pitch diameter is also known as the mean area of the screw shaft. Both of these dimensions are important when choosing the correct screw. A screw with a pitch of 1/8 will have a mechanical advantage of 6.3. For more information, consult an application engineer at Roton.
The pitch diameter of a screw shaft is measured as the distance between the crest and the root of the thread. Threads that are too long or too short will not fit together in an assembly. To measure pitch, use a measuring tool with a metric scale. If the pitch is too small, it will cause the screw to loosen or get stuck. Increasing the pitch will prevent this problem. As a result, screw diameter is critical.
The pitch diameter of a screw shaft is measured from the crest of one thread to the corresponding point on the next thread. Measurement is made from one thread to another, which is then measured using the pitch. Alternatively, the pitch diameter can be approximated by averaging the major and minor diameters. In most cases, the pitch diameter of a screw shaft is equal to the difference between the two.
The thread depth of a screw shaft
Often referred to as the major diameter, the thread depth is the outermost diameter of the screw. To measure the thread depth of a screw, use a steel rule, micrometer, or caliper. In general, the first number in the thread designation indicates the major diameter of the thread. If a section of the screw is worn, the thread depth will be smaller, and vice versa. Therefore, it is good practice to measure the section of the screw that receives the least amount of use.
In screw manufacturing, the thread depth is measured from the crest of the screw to the root. The pitch diameter is halfway between the major and minor diameters. The lead diameter represents the amount of linear distance traveled in one revolution. As the lead increases, the load capacity decreases. This measurement is primarily used in the construction of screws. However, it should not be used for precision machines. The thread depth of a screw shaft is essential for achieving accurate screw installation.
To measure the thread depth of a screw shaft, the manufacturer must first determine how much material the thread is exposed to. If the thread is exposed to side loads, it can cause the nut to wedge. Because the nut will be side loaded, its thread flanks will contact the nut. The less clearance between the nut and the screw, the lower the clearance between the nut and the screw. However, if the thread is centralized, there is no risk of the nut wedgeing.
The lead of a screw shaft
Pitch and lead are two measurements of a screw’s linear distance per turn. They’re often used interchangeably, but their definitions are not the same. The difference between them lies in the axial distance between adjacent threads. For single-start screws, the pitch is equal to the lead, while the lead of a multi-start screw is greater than the pitch. This difference is often referred to as backlash.
There are two ways to calculate the pitch and lead of a screw. For single-start screws, the lead and pitch are equal. Multiple-start screws, on the other hand, have multiple starts. The pitch of a multiple-start screw is the same as its lead, but with two or more threads running the length of the screw shaft. A square-thread screw is a better choice in applications requiring high load-bearing capacity and minimal friction losses.
The PV curve defines the safe operating limits of lead screw assemblies. It describes the inverse relationship between contact surface pressure and sliding velocity. As the load increases, the lead screw assembly must slow down in order to prevent irreversible damage from frictional heat. Furthermore, a lead screw assembly with a polymer nut must reduce rpm as the load increases. The more speed, the lower the load capacity. But, the PV factor must be below the maximum allowed value of the material used to make the screw shaft.
The thread angle of a screw shaft
The angle between the axes of a thread and the helix of a thread is called the thread angle. A unified thread has a 60-degree angle in all directions. Screws can have either a tapped hole or a captive screw. The screw pitch is measured in millimeters (mm) and is usually equal to the screw major diameter. In most cases, the thread angle will be equal to 60-degrees.
Screws with different angles have various degrees of thread. Originally, this was a problem because of the inconsistency in the threading. However, Sellers’s thread was easier to manufacture and was soon adopted as a standard throughout the United States. The United States government began to adopt this thread standard in the mid-1800s, and several influential corporations in the railroad industry endorsed it. The resulting standard is called the United States Standard thread, and it became part of the ASA’s Vol. 1 publication.
There are two types of screw threads: coarse and fine. The latter is easier to tighten and achieves tension at lower torques. On the other hand, the coarse thread is deeper than the fine one, making it easier to apply torque to the screw. The thread angle of a screw shaft will vary from bolt to bolt, but they will both fit in the same screw. This makes it easier to select the correct screw.
The tapped hole (or nut) into which the screw fits
A screw can be re-threaded without having to replace it altogether. The process is different than that of a standard bolt, because it requires threading and tapping. The size of a screw is typically specified by its major and minor diameters, which is the inside distance between threads. The thread pitch, which is the distance between each thread, is also specified. Thread pitch is often expressed in threads per inch.
Screws and bolts have different thread pitches. A coarse thread has fewer threads per inch and a longer distance between threads. It is therefore larger in diameter and longer than the material it is screwed into. A coarse thread is often designated with an “A” or “B” letter. The latter is generally used in smaller-scale metalworking applications. The class of threading is called a “threaded hole” and is designated by a letter.
A tapped hole is often a complication. There is a wide range of variations between the sizes of threaded holes and nut threads, so the tapped hole is a critical dimension in many applications. However, even if you choose a threaded screw that meets the requisite tolerance, there may be a mismatch in the thread pitch. This can prevent the screw from freely rotating.

Types of Screw Shafts
Screw shafts come in various types and sizes. These types include fully threaded, Lead, and Acme screws. Let’s explore these types in more detail. What type of screw shaft do you need? Which one is the best choice for your project? Here are some tips to choose the right screw:
Machined screw shaft
The screw shaft is a basic piece of machinery, but it can be further customized depending on the needs of the customer. Its features include high-precision threads and ridges. Machined screw shafts are generally manufactured using high-precision CNC machines or lathes. The types of screw shafts available vary in shape, size, and material. Different materials are suitable for different applications. This article will provide you with some examples of different types of screw shafts.
Ball screws are used for a variety of applications, including mounting machines, liquid crystal devices, measuring devices, and food and medical equipment. Various shapes are available, including miniature ball screws and nut brackets. They are also available without keyway. These components form a high-accuracy feed mechanism. Machined screw shafts are also available with various types of threaded ends for ease of assembly. The screw shaft is an integral part of linear motion systems.
When you need a machined screw shaft, you need to know the size of the threads. For smaller machine screws, you will need a mating part. For smaller screw sizes, the numbers will be denominated as industry Numeric Sizes. These denominations are not metric, but rather in mm, and they may not have a threads-per-inch designation. Similarly, larger machine screws will usually have threads that have a higher pitch than those with a lower pitch.
Another important feature of machine screws is that they have a thread on the entire shaft, unlike their normal counterparts. These machine screws have finer threads and are intended to be screwed into existing tapped holes using a nut. This means that these screws are generally stronger than other fasteners. They are usually used to hold together electronic components, industrial equipment, and engines. In addition to this, machine screws are usually made of a variety of materials.
Acme screw
An Acme screw is the most common type of threaded shaft available. It is available in a variety of materials including stainless steel and carbon steel. In many applications, it is used for large plates in crushing processes. ACME screws are self-locking and are ideal for applications requiring high clamping force and low friction. They also feature a variety of standard thread forms, including knurling and rolled worms.
Acme screws are available in a wide range of sizes, from 1/8″ to 6″. The diameter is measured from the outside of the screw to the bottom of the thread. The pitch is equal to the lead in a single start screw. The lead is equal to the pitch plus the number of starts. A screw of either type has a standard pitch and a lead. Acme screws are manufactured to be accurate and durable. They are also widely available in a wide range of materials and can be customized to fit your needs.
Another type of Acme screw is the ball screw. These have no back drive and are widely used in many applications. Aside from being lightweight, they are also able to move at faster speeds. A ball screw is similar to an Acme screw, but has a different shape. A ball screw is usually longer than an Acme screw. The ball screw is used for applications that require high linear speeds. An Acme screw is a common choice for many industries.
There are many factors that affect the speed and resolution of linear motion systems. For example, the nut position and the distance the screw travels can all affect the resolution. The total length of travel, the speed, and the duty cycle are all important. The lead size will affect the maximum linear speed and force output. If the screw is long, the greater the lead size, the higher the resolution. If the lead length is short, this may not be the most efficient option.
Lead screw
A lead screw is a threaded mechanical device. A lead screw consists of a cylindrical shaft, which includes a shallow thread portion and a tightly wound spring wire. This spring wire forms smooth, hard-spaced thread convolutions and provides wear-resistant engagement with the nut member. The wire’s leading and trailing ends are anchored to the shaft by means appropriate to the shaft’s composition. The screw is preferably made of stainless steel.
When selecting a lead screw, one should first determine its critical speed. The critical speed is the maximum rotations per minute based on the natural frequency of the screw. Excessive backlash will damage the lead screw. The maximum number of revolutions per minute depends on the screw’s minor diameter, length, assembly alignment, and end fixity. Ideally, the critical speed is 80% of its evaluated critical speed. A critical speed is not exceeded because excessive backlash would damage the lead screw and may be detrimental to the screw’s performance.
The PV curve defines the safe operating limits of a lead screw. This relationship describes the inverse relationship between contact surface pressure and sliding velocity. As the PV value increases, a lower rotation speed is required for heavier axial loads. Moreover, PV is affected by material and lubrication conditions. Besides, end fixity, which refers to the way the lead screw is supported, also affects its critical speed. Fixed-fixed and free end fixity are both possible.
Lead screws are widely used in industries and everyday appliances. In fact, they are used in robotics, lifting equipment, and industrial machinery. High-precision lead screws are widely used in the fields of engraving, fluid handling, data storage, and rapid prototyping. Moreover, they are also used in 3D printing and rapid prototyping. Lastly, lead screws are used in a wide range of applications, from measuring to assembly.
Fully threaded screw
A fully threaded screw shaft can be found in many applications. Threading is an important feature of screw systems and components. Screws with threaded shafts are often used to fix pieces of machinery together. Having fully threaded screw shafts ensures that screws can be installed without removing the nut or shaft. There are two major types of screw threads: coarse and fine. When it comes to coarse threads, UTS is the most common type, followed by BSP.
In the 1840s, a British engineer named Joseph Whitworth created a design that was widely used for screw threads. This design later became the British Standard Whitworth. This standard was used for screw threads in the United States during the 1840s and 1860s. But as screw threads evolved and international standards were established, this system remained largely unaltered. A new design proposed in 1864 by William Sellers improved upon Whitworth’s screw threads and simplified the pitch and surface finish.
Another reason for using fully threaded screws is their ability to reduce heat. When screw shafts are partially threaded, the bone grows up to the screw shaft and causes the cavity to be too narrow to remove it. Consequently, the screw is not capable of backing out. Therefore, fully threaded screws are the preferred choice for inter-fragmentary compression in children’s fractures. However, surgeons should know the potential complication when removing metalwork.
The full thread depth of a fully threaded screw is the distance at which a male thread can freely thread into the shaft. This dimension is typically one millimeter shy of the total depth of the drilled hole. This provides space for tap lead and chips. The full-thread depth also makes fully threaded screws ideal for axially-loaded connections. It is also suitable for retrofitting applications. For example, fully threaded screws are commonly used to connect two elements.
Ball screw
The basic static load rating of a ball screw is determined by the product of the maximum axial static load and the safety factor “s0”. This factor is determined by past experience in similar applications and should be selected according to the design requirements of the application. The basic static load rating is a good guideline for selecting a ball screw. There are several advantages to using a ball screw for a particular application. The following are some of the most common factors to consider when selecting a ball screw.
The critical speed limit of a ball screw is dependent on several factors. First of all, the critical speed depends on the mass, length and diameter of the shaft. Second, the deflection of the shaft and the type of end bearings determine the critical speed. Finally, the unsupported length is determined by the distance between the ball nut and end screw, which is also the distance between bearings. Generally, a ball screw with a diameter greater than 1.2 mm has a critical speed limit of 200 rpm.
The first step in manufacturing a high-quality ball screw is the choice of the right steel. While the steel used for manufacturing a ball screw has many advantages, its inherent quality is often compromised by microscopic inclusions. These microscopic inclusions may eventually lead to crack propagation, surface fatigue, and other problems. Fortunately, the technology used in steel production has advanced, making it possible to reduce the inclusion size to a minimum. However, higher-quality steels can be expensive. The best material for a ball screw is vacuum-degassed pure alloy steel.
The lead of a ball screw shaft is also an important factor to consider. The lead is the linear distance between the ball and the screw shaft. The lead can increase the amount of space between the balls and the screws. In turn, the lead increases the speed of a screw. If the lead of a ball screw is increased, it may increase its accuracy. If not, the lead of a ball screw can be improved through preloading, lubrication, and better mounting accuracy.

The Four Basic Components of a Screw Shaft
There are four basic components of a screw shaft: the Head, the Thread angle, and the Threaded shank. These components determine the length, shape, and quality of a screw. Understanding how these components work together can make purchasing screws easier. This article will cover these important factors and more. Once you know these, you can select the right type of screw for your project. If you need help choosing the correct type of screw, contact a qualified screw dealer.
Thread angle
The angle of a thread on a screw shaft is the difference between the two sides of the thread. Threads that are unified have a 60 degree angle. Screws have two parts: a major diameter, also known as the screw’s outside diameter, and a minor diameter, or the screw’s root diameter. A screw or nut has a major diameter and a minor diameter. Each has its own angle, but they all have one thing in common – the angle of thread is measured perpendicularly to the screw’s axis.
The pitch of a screw depends on the helix angle of the thread. In a single-start screw, the lead is equal to the pitch, and the thread angle of a multiple-start screw is based on the number of starts. Alternatively, you can use a square-threaded screw. Its square thread minimizes the contact surface between the nut and the screw, which improves efficiency and performance. A square thread requires fewer motors to transfer the same load, making it a good choice for heavy-duty applications.
A screw thread has four components. First, there is the pitch. This is the distance between the top and bottom surface of a nut. This is the distance the thread travels in a full revolution of the screw. Next, there is the pitch surface, which is the imaginary cylinder formed by the average of the crest and root height of each tooth. Next, there is the pitch angle, which is the angle between the pitch surface and the gear axis.
Head
There are three types of head for screws: flat, round, and hexagonal. They are used in industrial applications and have a flat outer face and a conical interior. Some varieties have a tamper-resistant pin in the head. These are usually used in the fabrication of bicycle parts. Some are lightweight, and can be easily carried from one place to another. This article will explain what each type of head is used for, and how to choose the right one for your screw.
The major diameter is the largest diameter of the thread. This is the distance between the crest and the root of the thread. The minor diameter is the smaller diameter and is the distance between the major and minor diameters. The minor diameter is half the major diameter. The major diameter is the upper surface of the thread. The minor diameter corresponds to the lower extreme of the thread. The thread angle is proportional to the distance between the major and minor diameters.
Lead screws are a more affordable option. They are easier to manufacture and less expensive than ball screws. They are also more efficient in vertical applications and low-speed operations. Some types of lead screws are also self-locking, and have a high coefficient of friction. Lead screws also have fewer parts. These types of screw shafts are available in various sizes and shapes. If you’re wondering which type of head of screw shaft to buy, this article is for you.
Threaded shank
Wood screws are made up of two parts: the head and the shank. The shank is not threaded all the way up. It is only partially threaded and contains the drive. This makes them less likely to overheat. Heads on wood screws include Oval, Round, Hex, Modified Truss, and Flat. Some of these are considered the “top” of the screw.
Screws come in many sizes and thread pitches. An M8 screw has a 1.25-mm thread pitch. The pitch indicates the distance between two identical threads. A pitch of one is greater than the other. The other is smaller and coarse. In most cases, the pitch of a screw is indicated by the letter M followed by the diameter in millimetres. Unless otherwise stated, the pitch of a screw is greater than its diameter.
Generally, the shank diameter is smaller than the head diameter. A nut with a drilled shank is commonly used. Moreover, a cotter pin nut is similar to a castle nut. Internal threads are usually created using a special tap for very hard metals. This tap must be followed by a regular tap. Slotted machine screws are usually sold packaged with nuts. Lastly, studs are often used in automotive and machine applications.
In general, screws with a metric thread are more difficult to install and remove. Fortunately, there are many different types of screw threads, which make replacing screws a breeze. In addition to these different sizes, many of these screws have safety wire holes to keep them from falling. These are just some of the differences between threaded screw and non-threaded. There are many different types of screw threads, and choosing the right one will depend on your needs and your budget.
Point
There are three types of screw heads with points: cone, oval, and half-dog. Each point is designed for a particular application, which determines its shape and tip. For screw applications, cone, oval, and half-dog points are common. Full dog points are not common, and they are available in a limited number of sizes and lengths. According to ASTM standards, point penetration contributes as much as 15% of the total holding power of the screw, but a cone-shaped point may be more preferred in some circumstances.
There are several types of set screws, each with its own advantage. Flat-head screws reduce indentation and frequent adjustment. Dog-point screws help maintain a secure grip by securing the collar to the screw shaft. Cup-point set screws, on the other hand, provide a slip-resistant connection. The diameter of a cup-point screw is usually half of its shaft diameter. If the screw is too small, it may slack and cause the screw collar to slip.
The UNF series has a larger area for tensile stress than coarse threads and is less prone to stripping. It’s used for external threads, limited engagement, and thinner walls. When using a UNF, always use a standard tap before a specialized tap. For example, a screw with a UNF point is the same size as a type C screw but with a shorter length.
Spacer
A spacer is an insulating material that sits between two parts and centers the shaft of a screw or other fastener. Spacers come in different sizes and shapes. Some of them are made of Teflon, which is thin and has a low coefficient of friction. Other materials used for spacers include steel, which is durable and works well in many applications. Plastic spacers are available in various thicknesses, ranging from 4.6 to 8 mm. They’re suitable for mounting gears and other items that require less contact surface.
These devices are used for precision fastening applications and are essential fastener accessories. They create clearance gaps between the two joined surfaces or components and enable the screw or bolt to be torqued correctly. Here’s a quick guide to help you choose the right spacer for the job. There are many different spacers available, and you should never be without one. All you need is a little research and common sense. And once you’re satisfied with your purchase, you can make a more informed decision.
A spacer is a component that allows the components to be spaced appropriately along a screw shaft. This tool is used to keep space between two objects, such as the spinning wheel and an adjacent metal structure. It also helps ensure that a competition game piece doesn’t rub against an adjacent metal structure. In addition to its common use, spacers can be used in many different situations. The next time you need a spacer, remember to check that the hole in your screw is threaded.
Nut
A nut is a simple device used to secure a screw shaft. The nut is fixed on each end of the screw shaft and rotates along its length. The nut is rotated by a motor, usually a stepper motor, which uses beam coupling to accommodate misalignments in the high-speed movement of the screw. Nuts are used to secure screw shafts to machined parts, and also to mount bearings on adapter sleeves and withdrawal sleeves.
There are several types of nut for screw shafts. Some have radial anti-backlash properties, which prevent unwanted radial clearances. In addition, they are designed to compensate for thread wear. Several nut styles are available, including anti-backlash radial nuts, which have a spring that pushes down on the nut’s flexible fingers. Axial anti-backlash nuts also provide thread-locking properties.
To install a ball nut, you must first align the tangs of the ball and nut. Then, you must place the adjusting nut on the shaft and tighten it against the spacer and spring washer. Then, you need to lubricate the threads, the ball grooves, and the spring washers. Once you’ve installed the nut, you can now install the ball screw assembly.
A nut for screw shaft can be made with either a ball or a socket. These types differ from hex nuts in that they don’t need end support bearings, and are rigidly mounted at the ends. These screws can also have internal cooling mechanisms to improve rigidity. In this way, they are easier to tension than rotating screws. You can also buy hollow stationary screws for rotator nut assemblies. This type is great for applications requiring high heat and wide temperature changes, but you should be sure to follow the manufacturer’s instructions.
