Scroll Saw Safety

Explanation
The statement is false because you do need permission to use the scroll saw. Using power tools like a scroll saw can be dangerous and requires proper training and supervision. Permission from a supervisor or instructor is necessary to ensure that the user has the necessary skills and knowledge to operate the tool safely.

Explanation
To use this machine, safety glasses must be worn. This is because the machine may emit debris or particles that could potentially harm the eyes. Wearing safety glasses provides a protective barrier and reduces the risk of eye injuries.

Explanation
When installing a blade, it is important to ensure that the teeth are pointing downwards. This is because the teeth of the blade are designed to cut through the material being worked on in a specific direction. By pointing the teeth downwards, the blade will be able to effectively cut through the material and achieve the desired result. Installing the blade with the teeth pointing in any other direction may result in ineffective cutting or even damage to the blade or the material being worked on.

Explanation
It is important to never place hands in the blade path to avoid injury. Placing hands in the path of a blade can result in severe cuts or amputations. It is crucial to always keep hands and fingers away from the blade while using any type of equipment or machinery with a rotating blade.

Explanation
When using a blade to cut wood, it is important to slow down and release pressure at the point where the blade is about to cut completely through the wood. This is because if there is too much pressure on the board, there is a risk of the hand slipping and going into the blade. By slowing down and releasing pressure, the risk of accidents can be minimized, ensuring safety while cutting wood.

Explanation
To keep the blade from breaking, it is important to continuously push or "feed" the wood into the blade as you are turning. This ensures a steady and controlled cutting process, preventing the blade from becoming overloaded or getting stuck, which could result in breakage.

Explanation
The scroll saw is a versatile tool that can be used to cut very sharp curves. However, it is important to note that when using the scroll saw, you should cut as you turn and avoid stopping and turning, as this can cause the blade to break.

Explanation
When cutting on a machine, it is important to always have a buddy or someone with you for safety purposes. The buddy can help ensure that the cutting process is done correctly and can provide assistance in case of any accidents or emergencies. Therefore, having a "cutter buddy" with you is crucial to maintain a safe working environment.

Explanation
It is false that one should never change the blade on the machine and always rely on the instructor to do so. This statement is incorrect because it is important for individuals to learn how to change the blade on the machine themselves. By doing so, they can ensure that the blade is properly maintained and replaced when necessary. Relying solely on the instructor for this task may create delays and hinder productivity.

Explanation
When a blade breaks, it is important to stop the machine first to prevent any further damage or injury. Continuing to use the machine with a broken blade can lead to accidents or damage to the workpiece. Once the machine is stopped, the blade can be safely changed to ensure smooth and safe operation.

Explanation
Little pieces that are cut off should always be thrown into the trash can immediately to ensure cleanliness and prevent any potential hazards. Leaving them on the table or tossing them to the floor and picking them up later can create a mess and increase the risk of accidents or injuries. Ignoring them is not a responsible option as it can lead to further clutter and potential hygiene issues. Therefore, throwing them into the trash can immediately is the most appropriate and sensible choice.

Explanation
When cutting a piece, it is important for students to follow the outside part of the cut line. This means that they should cut just outside the line they have drawn on the board. By doing so, they ensure that they are not cutting into the actual piece that they want to keep. If they were to cut on the inside or middle of the cut line, they would risk cutting into the piece and potentially ruining it. The suggestion to sand it down later implies that cutting on the outside allows for some margin of error, which can be corrected during the sanding process.

Explanation
Setting the tension lever or knob to the highest tension before changing the blade is not necessary. The tension lever or knob should be adjusted based on the specific requirements of the blade being used and the material being cut. Setting it to the highest tension may cause unnecessary strain on the blade and could potentially lead to damage or breakage. Therefore, the correct answer is false.
