The hold-down attachment should rest firmly on the work to prevent the
- A.
Blade from overheating.
- B.
Motor from being overloaded.
- C.
Work from vibrating up and down.
Correct Answer
C. Work from vibrating up and down.Explanation
The hold-down attachment is designed to keep the workpiece securely in place during operation. By resting firmly on the work, it prevents any unwanted movement or vibration that could occur while the blade is cutting. This not only ensures accurate and precise cuts but also prevents any potential damage to the workpiece or the blade. By stabilizing the work, the hold-down attachment also helps to minimize the risk of accidents or injuries caused by the workpiece moving or slipping during cutting.Rate this question:

Set the _______________________down against the stock before turning on the power.
- A.
Saw blade
- B.
Hold-down assembly
- C.
Double chuck
Correct Answer
B. Hold-down assemblyExplanation
Before turning on the power, it is important to set the hold-down assembly down against the stock. This is necessary to ensure that the stock is securely held in place during the cutting process. The hold-down assembly typically consists of clamps or other mechanisms that prevent the stock from moving or shifting while the saw blade is in motion. By using the hold-down assembly, the risk of accidents or injuries caused by the stock moving unexpectedly is reduced, making it an essential safety precaution.Rate this question:

. Before you turn on the scroll saw, be sure that the ________________________is properly adjusted to keep the blade from bending or breaking
- A.
Upper plunger
- B.
Hold-down assembly
- C.
Saw blade tension
- D.
Hand wheel
Correct Answer
C. Saw blade tensionExplanation
Before you turn on the scroll saw, be sure that the saw blade tension is properly adjusted to keep the blade from bending or breaking. This is important because the tension of the blade affects its performance and stability while cutting. If the tension is too loose, the blade may wander or vibrate, leading to inaccurate cuts or potential damage. On the other hand, if the tension is too tight, it can put excessive stress on the blade, causing it to break. Therefore, adjusting the saw blade tension correctly is crucial for safe and efficient operation of the scroll saw.Rate this question:

When the blade is installed correctly, the teeth are pointing______________________.
Correct Answer
down
downwardExplanation
When the blade is installed correctly, the teeth are pointing down or downward. This is because the teeth of the blade are designed to cut through material in a specific direction, and having them point downward ensures that they make contact with the material and can effectively cut through it. Installing the blade in any other direction would result in ineffective cutting or potential damage to the blade or the material being cut.Rate this question:

The blade _____________________must be properly adjusted.
Correct Answer
tensionExplanation
The blade must be properly adjusted in terms of tension. This means that the tension of the blade needs to be set correctly in order for it to function effectively. If the tension is too loose, the blade may not cut properly or may become dislodged. On the other hand, if the tension is too tight, it can put unnecessary strain on the blade and potentially cause it to break. Therefore, it is important to ensure that the tension of the blade is adjusted correctly for optimal performance.Rate this question:
