Cleaning The Air Filter; Checking The Relief Valve; Testing For Leaks - Craftsman 921.16477 Owner's Manual

CLEANING THE
AIR FILTER
A dirty air filter will
reduce the A = Wing nut
B = Metal cover
compressor's 8 C C = Filter element
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
reinstaltation. 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 wilt 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
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.
