Ps:1 Router Safety Safety Exam

It is important to check that the power switch is in the off position before connecting the router's power cord to the outlet to ensure safety. This step helps prevent any electrical accidents or damage that may occur if the power switch is left on while connecting the power cord. By turning off the power switch, there is no risk of electric shock or short circuiting the device. Therefore, the statement is true.

When changing a router bit, it is important to ensure safety by turning off the power switch of the router and unplugging it. This precautionary measure prevents any accidental activation of the router while handling the bit, reducing the risk of injury. By following this practice, one can safely change the router bit without any potential harm.

Using a dull router bit is not okay, even when routing soft woods such as pine and balsa. A dull router bit can cause tear-out, rough cuts, and can be dangerous as it requires more force to operate. It is important to always use a sharp router bit for clean and safe cuts, regardless of the type of wood being routed.

The statement suggests that the router bit left in the router from a previous user is secure in the router's collet. However, this is not necessarily true. The collet is the part of the router that holds the bit in place, and it is possible for the bit to become loose or fall out if it is not properly secured. Therefore, it is not safe to assume that the router bit left in the router from a previous user is secure in the collet.

It is important to allow the router to come to a complete stop before setting it down on the table or workbench to ensure safety. If the router is still running or has moving parts when placed on a surface, it can cause damage to the router or the surface, and also pose a risk of injury to the user. Therefore, it is necessary to wait for the router to stop completely before placing it down.

The statement suggests that the collet nut should always be tightened by hand. However, this is not necessarily true. Depending on the specific situation and the tool being used, it may be necessary to use a wrench or other tool to properly tighten the collet nut. Therefore, the correct answer is false.

It is not recommended to begin cutting with the router before the motor gets the full speed when starting. Starting the router at full speed ensures that the tool is operating at its optimal performance and reduces the risk of accidents or damage to the workpiece. Therefore, the correct answer is False.

Pushing the router bit up into the collet at least 1" or as far as it will go ensures that the bit is securely held in place and reduces the risk of it coming loose during operation. This is important for safety reasons as a loose bit can cause accidents and damage to the workpiece. Additionally, having the bit inserted fully into the collet allows for optimal performance and accuracy when using the router.

The statement is false because holding the stock by hand does not necessarily prevent infeed vibrations. Infeed vibrations can be caused by various factors such as the type of machinery used, the speed at which the stock is fed, and the condition of the stock itself. Holding the stock by hand may provide some stability, but it is not a foolproof method to avoid infeed vibrations. Other measures such as using proper clamping devices or adjusting the machinery settings may be necessary to minimize vibrations.

Storing the router with the bit left in the router chuck collet can actually cause the collet to become stuck or jammed over time. It is recommended to remove the bit from the collet after use and store them separately to prevent any damage or issues with the collet.

The statement is false because wood should always be fed against the direction of motor rotation. This is because feeding wood in the same direction as the motor rotation can cause kickback, where the wood is forcefully thrown back towards the operator, leading to potential injuries. Feeding wood against the rotation helps to prevent kickback and ensures safer operation.
