Ps:1 Scroll Saw Safety Exam

It is important to check the blade tension before cutting to ensure the blade is properly tightened. If the blade tension is too loose, it can result in an inefficient or inaccurate cut, while if the tension is too tight, it can cause the blade to break or wear out quickly. Therefore, checking the blade tension before cutting is necessary to ensure safe and effective cutting operations.

The statement is true because it is important to adjust the blade tension of a saw while it is stopped. Adjusting the tension while the saw is running can be dangerous and can lead to accidents or injuries. By stopping the saw before making any adjustments, the risk of accidents is minimized, allowing for safer and more accurate adjustments to be made.

It is important to adjust the tension arm every time a new blade is installed to ensure proper tension is applied to the blade. This helps in achieving accurate and precise cuts, as the tension arm maintains the correct amount of tension on the blade during operation. Failing to adjust the tension arm may result in the blade being too loose or too tight, leading to poor cutting performance and potential damage to the blade or the machine.

It is important to never have your fingers closer than 3" to the blade to ensure safety while using a blade or any sharp object. This distance helps to prevent accidental injuries and cuts. Therefore, the statement "Never have your fingers closer than 3" to the blade" is true.

The statement is advising to turn off the machine and stop the blade before backing out of a cut. This is a safety precaution to prevent accidents or injuries. By turning off the machine and stopping the blade, the risk of accidentally coming into contact with the blade while backing out of the cut is minimized. Therefore, the statement is true.

It is not true that one should always attempt to turn curves that are too sharp for the blade. Turning sharp curves can put strain on the blade and potentially cause damage. It is important to use the appropriate tools and techniques to navigate sharp curves safely and effectively.

The statement is true because if a workpiece does not have a flat bottom that can rest on the table, it may not be stable or secure during the cutting process. This can lead to accidents or errors in the cutting operation. It is important to ensure that the workpiece is properly supported and stable on the table before attempting to cut it.

The statement suggests that if the saw being used is variable speed, then any speed can be chosen based on the desired cutting speed. However, the correct answer is false because the speed at which the saw operates should be determined by the material being cut, not just the desired cutting speed. Different materials require different speeds to ensure clean and efficient cuts, so it is not accurate to say that any speed can be used solely based on the desired cutting speed.

The blades teeth should actually point downwards, not upwards. This is because when the blade rotates, the teeth will cut through the material being worked on in a more efficient and effective manner. If the teeth were pointing upwards, it would make the cutting process more difficult and less precise. Therefore, the correct answer is False.

The statement suggests that the saw should be operated with the hold-down safety guard positioned 1/8" to 1/4" above the stock. However, the correct answer is False. The hold-down safety guard should be positioned as close to the stock as possible to minimize the risk of kickback and ensure safe operation.
