1. Check to make sure there is adequate belt tension. You should have anywhere from 1/4” - 3/8” movement
when applying 50% pressure to the belt directly between the motor and pump pulleys
2. Check to make sure that the motor and compressor are securely fastened to the frame. Make sure that bolts
have not come loose.

1. Check to see if you have any external air leaks
- Disconnect any air storage tanks and plug tank supply line and run compressor to see if pressure

1. You probably don’t have an external air storage supply tank. The compressor is shutting down with 150
PSI in the air lines and a small leak is draining the pressure down to 125 PSI and the compressor is
kicking back on to build the pressure back up to 150 PSI.
