The blade guard must revolve up into the upper guard assembly ________.
Correct Answer
A. Without sticking or binding
Explanation
The blade guard must revolve up into the upper guard assembly without sticking or binding to ensure smooth and unhindered movement. This is important for the safety and proper functioning of the tool. If the blade guard sticks or binds, it can cause accidents or interfere with the cutting process. Therefore, it is necessary for the blade guard to move freely without any obstruction or resistance.
3.
Check the blade for ________.
Correct Answer
D. The proper cutting application for the job
Explanation
When checking the blade, it is important to ensure that it is suitable for the specific cutting application required for the job. Different blades are designed for different materials and cutting techniques, so using the proper blade will ensure efficient and effective cutting. Checking the blade for the proper cutting application helps to prevent damage to the blade, avoid accidents, and achieve the desired results.

Before starting a cutting operation, you should set the proper cutting depth at ________ the thickness of the stock you are cutting.
Correct Answer
A. 1/16 inch below
Explanation
Before starting a cutting operation, it is important to set the proper cutting depth. Setting the cutting depth at 1/16 inch below the thickness of the stock being cut ensures that the blade cuts through the material without going too deep. This helps to prevent damage to the stock and ensures a clean and precise cut.
5.
All stock must be supported so that the rotating gaurd ________ during the complete cutting operation.
Correct Answer
B. Will not bind and move freely
Explanation
The correct answer is "will not bind and move freely". This means that in order for the rotating guard to function effectively during the cutting operation, the stock must be supported in a way that prevents it from getting stuck or obstructed and allows it to move smoothly without any restrictions.
