1.
When using a sander, do not________________ your work.
Correct Answer
A. Lean too close to
Explanation
When using a sander, it is important not to lean too close to your work. Leaning too close can increase the risk of injury, such as getting your fingers caught in the sander or inhaling dust particles. It is important to maintain a safe distance from the sander while using it to ensure your safety and the quality of your work.
2.
When sanding, protect your eyes from flying chips and torn abrasive paper by___________________
.
Correct Answer
C. Wearing approved eye protection
Explanation
When sanding, it is important to protect your eyes from potential hazards such as flying chips and torn abrasive paper. Wearing approved eye protection is the best way to ensure your eyes are shielded from any debris that may be generated during the sanding process. Regular eye glasses may not provide sufficient protection and standing in the operator's position or away from it does not address the need for eye protection. Therefore, wearing approved eye protection is the correct answer.
3.
You should not use a sander belt___________________ .
Correct Answer
D. With torn edges
Explanation
Using a sander belt with torn edges is not recommended because it can lead to uneven sanding and may cause damage to the material being worked on. Torn edges can create rough surfaces on the belt, which can result in inconsistent sanding and potentially ruin the desired finish. It is important to use a sander belt that is in good condition to ensure smooth and effective sanding.
4.
If the belt does not run____________________ , turn the machine off
and report it to the teacher.
Correct Answer
C. In the center of the rolls
Explanation
If the belt does not run in the center of the rolls, it may indicate a misalignment or malfunction in the machine. This could potentially cause damage or accidents, so it is important to turn off the machine and inform the teacher for further assistance.
5.
Always keep articles that you are sanding_______________________ .
Correct Answer
A. In contact with the table
Explanation
When sanding, it is important to keep the articles in contact with the table. This ensures stability and prevents the articles from moving or slipping during the sanding process. By maintaining contact with the table, the sanding can be done accurately and evenly, resulting in a better finish. Keeping the articles in contact with the table also helps to prevent any potential accidents or injuries that may occur if the articles are not properly secured.
6.
Do not use sanding belts or discs that are .
Correct Answer
B. Loaded with pitch and/or worn out
Explanation
Using sanding belts or discs that are loaded with pitch and/or worn out can be detrimental to the sanding process. When a sanding belt or disc is loaded with pitch, it means that it has accumulated a sticky residue from the material being sanded. This can result in reduced effectiveness and clogging of the abrasive surface. Similarly, using worn-out sanding belts or discs can lead to uneven sanding and poor results. Therefore, it is important to avoid using sanding belts or discs that are loaded with pitch and/or worn out.
7.
Do not try to shorten the sanding process by pressing hard on your work or holding the
sander in one spot for a long time. This will burn your work and may cause the belts or discs
to break and __________________________________.
Correct Answer
D. Injure you
Explanation
Pressing hard on the work or holding the sander in one spot for a long time can cause the sanding belts or discs to break, which can lead to injury. When the belts or discs break, they can potentially fly off the sander and cause harm to the person operating it or anyone nearby. It is important to maintain a steady and even pressure while sanding to avoid any accidents or injuries.
8.
Be sure to use only half of the disc moving______________ . If the wrong
half is used, the work may be thrown upward.
Correct Answer
C. Downward
Explanation
Using only half of the disc moving downward is important because if the wrong half is used, the work may be thrown upward. This suggests that there is a specific way to manipulate the disc in order to achieve the desired outcome.
9.
Before you turn on the power, check carefully to see that the abrasive disc is_______________
to the disc and has no loose or torn edges.
Correct Answer
A. Tightly cemented
Explanation
Before turning on the power, it is important to check that the abrasive disc is tightly cemented to the disc and has no loose or torn edges. This is crucial for safety and efficiency during operation. If the abrasive disc is not tightly cemented, it may become loose or detach while in use, potentially causing accidents or damage. Additionally, loose or torn edges can affect the performance and effectiveness of the disc, leading to subpar results. Therefore, ensuring that the disc is tightly cemented and free from any loose or torn edges is essential.
10.
Do not put____________ on top of the sander.
Correct Answer
C. Pressure
Explanation
Putting pressure on top of the sander can cause damage to the sander or the surface being sanded. Excessive pressure can lead to uneven sanding or even create gouges in the material. It is important to let the sander do the work and apply gentle, even pressure to achieve the desired results.
11.
Be sure the sandpaper covers the sanding pad.
Correct Answer
A. Completely
Explanation
To ensure effective sanding, it is important for the sandpaper to fully cover the sanding pad. This allows for maximum contact between the sandpaper and the surface being sanded, resulting in a smoother and more even finish. If the sandpaper is not completely covering the pad, it may lead to uneven sanding or missed spots. Therefore, it is crucial to ensure that the sandpaper is properly and completely attached to the sanding pad.
12.
Material less than inches long should not be sanded with a
portable belt sander.
.
Correct Answer
B. 12
13.
2. When the sander is not in use,_______________________ . The sander in this position will not
travel if accidentally turned on.
Correct Answer
D. Lay it on its side
Explanation
When the sander is not in use, it is recommended to lay it on its side. By doing so, the sander will not accidentally travel or move if it is turned on unintentionally. Placing it on its side ensures that it remains stable and secure, minimizing the risk of any accidents or damage.
14.
3. Do not press down on the___________ for faster sanding. This will overheat
the sander and clog the belt.
A. C.
B. D.
Correct Answer
C. Sander
Explanation
Pressing down on the sander for faster sanding can overheat the sander and clog the belt. This is because excessive pressure can cause friction, which generates heat and can damage the sander. Additionally, pressing down too hard can also cause the belt to become clogged with debris, reducing its effectiveness. Therefore, it is important to avoid pressing down on the sander and instead let the sander do the work at its own pace.
15.
Always sand__________________ direction of the spindle movement.
Correct Answer
A. In the opposite
Explanation
When sanding, it is important to always sand in the opposite direction of the spindle movement. This is because sanding in the same direction can cause the sandpaper to slip or tear, resulting in an uneven or damaged surface. Sanding at a 90-degree angle from the spindle movement may not provide enough contact with the surface and may not effectively remove material. Sanding in any random direction can also lead to inconsistent results. Therefore, sanding in the opposite direction ensures proper sanding and achieves a smooth and even finish.
16.
Select the proper table insert to fit _________________________.
Correct Answer
C. The drum diameter
Explanation
The correct answer is "the drum diameter". This means that the table insert should be selected based on the diameter of the drum. The table insert should be able to accommodate the size of the drum, ensuring a proper fit.
