GENERAL MAINTENANCE

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.
