AIR FILTER INSPECTION
AND REPLACEMENT
Hot sur-
faces. Risk of burn.
Compressor heads are
exposed when filter
cover is removed. Allow
compressor to cool prior
to servicing.
A dirty air filter will not
allow the compressor to
operate at full capacity.
Keep the air filter clean at
all times.
1. Remove the air filter
cover.
2. Remove the air filter and
make sure it is clean.
IMPORTANT
: Do not oper-
ate the compressor with the
air filter removed.

To ensure efficient operation
and longer life of the air
compressor, a routine main-
tenance schedule should be
prepared and followed. The
following routine mainte-
nance schedule is geared to
an air compressor in a nor-
mal working environment
operating on a daily basis. If
necessary, the schedule
should be modified to suit
the conditions under which
your air compressor is used.
The modifications will
depend upon the hours of
operation and the working
environment. An air com-
pressor in an extremely dirty
and/or hostile environment
will require a greater fre-
quency of all maintenance
checks.
Unit cycles
automatically when
power is on. When per-
forming maintenance,
you may be exposed to
voltage sources, com-
pressed air, or moving
parts. Personal injuries
can occur. Before per-
forming any maintenance
or repair, disconnect
power source from the
compressor and bleed off
all air pressure.
TO CHECK SAFETY
VALVE
If the safety
valve does not work
properly, over-pressuriza-
tion may occur, causing
air tank rupture or an
explosion.
Before starting compressor,
pull the ring on the safety
valve to make sure that the
safety valve operates freely.
If the valve is stuck or does
not operate smoothly, it
must be replaced with the
same type of valve.
TO DRAIN TANK
1. Set the On/Auto/Off lever
to “OFF”.
2. Pull the regulator knob
out and turn clockwise to
set the outlet pressure to
zero.
3. Remove the air tool or
accessory.
4. Pull ring on safety valve
allowing air to bleed from
the tank until tank pres-
sure is approximately 20
psi. Release safety valve
ring.
5. Drain water from air tank
by opening drain valve
(counter-clockwise) on
bottom of tank.
Water will
condense in the air tank.
If not drained, water will
corrode and weaken the
air tank causing a risk of
air tank rupture.
6. After the water has been
drained, close the drain
valve (clockwise). The air
compressor can now be
stored.
NOTE
: If drain valve is
clogged, release all air pres-
sure. The valve can then be
removed, cleaned, and then
reinstalled.
NOTE:
See “Operation” sec-
tion for the location of con-
trols.
