Cleaning The Air Filter; Checking The Relief Valve; Testing For Leaks - Craftsman 921.16475 Manual Del Usuario

CLEANING THE AIR FILTER
A dirty air filter wilt 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 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 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 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 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.
