Humidity in the air causes condensation to form in the air tank. This condensation should be drained daily and/or every hour, using the instructions found in Draining the tank.

The safety valve automatically releases air if the air receiver pressure exceeds the preset maximum. Check the safety valve before each use following the instructions found in Checking the safety valve.

Inspect the tank yearly for rust, pin holes, or other imperfections that could cause it to become unsafe.

All the bearings in this tool are lubricated with a sufficient amount of high grade lubricant for the life of the unit under normal operating conditions. Therefore, no further lubrication of the bearings is required.
