FILTER
The air filter keeps moisture and dirt out of the cylinders and other components. The
filter bowl must be kept free of moisture. Filter bowls that fill quickly with water
indicate a problem with the air dryer. If your air system does not include a dryer, the
filters on all machines must be checked and/or drained daily.
This is best done by pressing on the drain valve until all moisture blows free. The
moisture can be caught in a towel.
CAUTION
: IF THE FILTER BOWL IS CRACKED,
IT MUST BE REPLACED IMMEDIATELY.
NOTICE
: IF FILTER BOWL IS
CRACKED, AN AIR LEAK COULD RUN THE COMPRESSOR CONTINUOUSLY,
PUTTING EXCESSIVE WEAR ON THE COMPRESSOR.
The internal parts of the filter and the bowl can be cleaned. Always decrease resistance
to zero before starting service or repair on any K300 machine.
To service:
Unplug the quick-disconnect and unscrew the bowl and element holder from the housing.
Clean all parts with dish soap and water. Do not use solvent or other strong chemicals on
any part of the filter. Allow the element to dry thoroughly. Lightly coat the bowl seal
with SAE 30 wt. Oil and reassemble. Leaky drain valves can be replaced with a bicycle
tire tube valve available at most hardware stores.
