CHECKING AND CHANGING AIR
INTAKE FILTER
NOTE
Keep the air filter clean at all times. Do
not operate compressor outfit when
the filters are removed.
The condition of the air intake filter should be checked
once a week. A dirty air intake filter will not allow the
compressor to operate at full capacity and will increase
oil usage.
When the air filter becomes dirty, oily, or covered with
paint overspray it must be replaced. To check and/or
replace the air intake filter, remove the screw securing
the filter assembly to the air compressor pump. Re-
move the filter. Inspect condition of filter; replace if
necessary.
NOTE
Felt and foam intake filters can be
washed in non-explosive solvent.
Allow to dry and reinstall. DO NOT OIL
INTAKE FILTERS.
DRAINING WATER FROM AIR TANK
Water will condense in the air tank.
If not drained, the water will corrode
and weaken the air tank. A weakened
tank may explode or rupture causing
personal injury. Drain the tank as
instructed below.
Water should be drained from the air tank daily. If
humidity is high the tank should be drained at regular
intervals during the day. Operate the compressor
outfit to allow 15 to 20 psi air pressure in the tank.
Open the drain valve. Continue operating outfit until
all moisture is removed from the tank. Close the drain
valve tightly.
NOTE
If the draincock is clogged, release
the air pressure in the tank. Remove
the drain valve and clean or replace.
Apply sealant to the threads before
reinstalling the drain valve.
CHECKING AND ADJUSTING BELT
TENSION
Serious injury or damage may occur
if parts of the body or loose items get
caught in moving parts. Never operate
the compressor outfit with the belt
guard removed. The belt guard should
only be removed after the spark plug
wire has been disconnected.
The drive belt should be kept in proper tension as a
loose belt will slip and wear faster. An over tightened
belt will place an excessive load on the engine and
compressor pump bearings causing premature fail-
ure. The belt tension should be checked as follows:
1. Disconnect the spark plug wire and drain all air
pressure from the air tank.
2. Remove the belt guard.
3. Loosen all engine mounting hardware and slide
the engine either toward or away from the
compressor until correct belt tension is
achieved.
