9. Replace the transfer tube and tighten compression nuts.
10. Perform the "Break-in of the pump" procedure in the
Operating Instructions to make sure there are no leaks and
the check valve is working properly.
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 tank safety 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 over tighten 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 tank safety
