What should be the distance between the tool rest and the wheel on a bench grinder?
Correct Answer
A. 1/8 inch
Explanation
The distance between the tool rest and the wheel on a bench grinder should be 1/8 inch. This is because having a small gap between the tool rest and the wheel allows for better control and precision when using the grinder. It also helps to prevent the tool from getting caught or jammed between the rest and the wheel, reducing the risk of accidents or damage to the tool.

Before attempting repairs on a pneumatic nailer that is not firing, you should do what?
Correct Answer
B. Disconnect the air hose
Explanation
Before attempting repairs on a pneumatic nailer that is not firing, it is important to disconnect the air hose. This is necessary to ensure the safety of the person working on the nailer. By disconnecting the air hose, the flow of compressed air to the nailer is stopped, reducing the risk of accidental firing or injury. Once the air hose is disconnected, it is then safe to proceed with the repairs or troubleshooting of the pneumatic nailer.
7.
What should be added to the air inlet of a pneumatic nail gun after every use?
Correct Answer
A. Oil
Explanation
Oil should be added to the air inlet of a pneumatic nail gun after every use. This is because the air inlet requires lubrication to ensure smooth operation and prevent damage to the internal components. Oil acts as a lubricant, reducing friction and extending the lifespan of the nail gun. Without regular oiling, the nail gun may experience increased wear and tear, leading to malfunctions and decreased performance. Therefore, adding oil to the air inlet is necessary maintenance for the proper functioning of a pneumatic nail gun.
