MAINTENANCE

SERVICE INTERVAL

CLEANING THE AIR FILTER

A dirty air filter will reduce the compressor’s performance and life. To avoid 

any internal contamination of the pump, the filter should be cleaned frequently, 

and replaced on a regular basis. Felt filters should be cleaned in warm, soapy 

water, rinsed, and allowed to air dry before reinstallation. Paper filters should be 

replaced when dirty. Do not allow the filter to become filled with dirt or paint. If 

the filter becomes filled with paint, it should be replaced. Direct exposure to dirty 

conditions or painting areas will void your warranty.

CHECKING THE RELIEF VALVE

Pull the relief valve daily to ensure that it is operating properly and to clear the 

valve of any possible obstructions.

TESTING FOR LEAKS

Check that all connections are tight. A small leak in any of the hoses, transfer 

tubes, or pipe connections will substantially reduce the performance of your air 

compressor. If you suspect a leak, spray a small amount of soapy water around 

the area of the suspected leak with a spray bottle. If bubbles appear, repair or 

replace the faulty component. Do not overtighten any connections.

STORAGE

Before storing the compressor for a prolonged period, use an air blow gun to 

clean all dust and debris from the compressor. Disconnect the power cord and 

coil it up. Pull the pressure relief valve to release all pressure from the tank. Drain 

all moisture from the tank. Clean the filter element and filter housing; replace the 

element if necessary. Drain the oil from the pump crankcase and replace it with 

new oil. Cover the entire unit to protect it from moisture and dust.

Perform the following maintenance at the intervals indicated below.
