The student should check that the ________ is in the off position before plugging the saw into the power outlet.
Correct Answer
D. Switch
Explanation
Before plugging the saw into the power outlet, the student should check that the switch is in the off position. This is important to ensure safety and prevent any accidental activation of the saw's motor. By confirming that the switch is off, the student can avoid any potential hazards or injuries that may occur if the saw were to unexpectedly turn on while being plugged in.
2.
The student should check that the ________ is being used for the cut and that it is properly installed.
Correct Answer
B. Proper blade
Explanation
The student should check that the proper blade is being used for the cut and that it is properly installed. This is important because using the wrong blade can result in inefficient cutting or damage to the material being cut. Additionally, if the blade is not properly installed, it may not function correctly or could pose a safety risk. Therefore, ensuring the use of the proper blade and its proper installation is crucial for achieving accurate and safe cutting results.
3.
The student should place the saw base plate ________ the material to be cut before turning the power.
Correct Answer
B. Firmly on
Explanation
The student should place the saw base plate firmly on the material to be cut before turning the power. This is important because placing the base plate firmly on the material ensures stability and prevents the saw from slipping or moving during the cutting process. It also helps to maintain accuracy and control while cutting.
4.
The blade must not touch the material when the power is turned on. Turning on the power with the blade touching the material can ________.
Correct Answer
C. Break the blade
Explanation
When the power is turned on and the blade is touching the material, it creates a lot of friction and resistance. This can cause excessive strain on the blade, leading to it breaking. The force exerted by the blade against the material can be too much for it to handle, causing it to snap or fracture. Therefore, it is important to ensure that the blade does not touch the material when the power is turned on to prevent any damage or breakage.
5.
Do not cut the radius so small that it binds or bends the blade. This may cause the blade to ________.
Correct Answer
D. Break
Explanation
Cutting a radius that is too small and causes the blade to bind or bend can lead to excessive stress on the blade. This increased stress can ultimately cause the blade to break.
6.
Do not saw into the ________.
Correct Answer
B. Supporting work surface
Explanation
The phrase "do not saw into the supporting work surface" suggests that one should avoid cutting or damaging the surface that is providing support or stability for the task at hand. This cautionary statement is likely referring to a situation where sawing or cutting is taking place, and it is important to be mindful of not causing any harm to the surface that is aiding in the process.
7.
The student must check that there is sufficient electrical cord length to ________.
Correct Answer
C. Complete the cut
Explanation
The student must check that there is sufficient electrical cord length to complete the cut. This means that the cord should be long enough to allow for the entire cutting process without running out of length. If the cord is too short, the student may not be able to finish the cut and may need to find a longer cord or extension to complete the task.
8.
The student must make sure that the blade does not come into contact with the ________ during the cutting operation.
Correct Answer
C. Cord
Explanation
During the cutting operation, it is important for the student to ensure that the blade does not come into contact with the cord. This is because the cord can get tangled in the blade, causing accidents or damage to the equipment. Keeping the blade away from the cord ensures safe and efficient cutting.
9.
Be sure ________ before changing blades or doing any adjustments to the sabre saw.
Correct Answer
D. The saw is unplugged from the power source
Explanation
Before changing blades or making any adjustments to the sabre saw, it is important to ensure that the saw is unplugged from the power source. This is crucial for the safety of the person handling the saw, as it eliminates the risk of accidental starting or electrocution. By unplugging the saw, one can be certain that there is no power running to the tool, making it safe to work on.
