Checking Safety valve (Fig. 1)
WARNING: Hot surfaces. Risk of burn. Aftercooler, pump head, and
surrounding parts are very hot, do not touch (see the Hot Surfaces
identified in Fig. 2). Allow compressor to cool prior to servicing.
WARNING: Risk of bursting. If the safety valve does not work
properly, over-pressurization 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.
Checking Air Filter Element (Fig. 1)
WARNING: Hot surfaces. Risk of burn. Aftercooler, pump head, and
surrounding parts are very hot, do not touch (see the Hot Surfaces
identified in Fig. 2). Allow compressor to cool prior to servicing.
1. Ensure engine ON/OFF switch (C) is in the OFF position.
. Allow unit to cool.
3. Remove filter (A) top from filter base by turning filter counter-
clockwise about 5 degrees.
4. Separate filter top from base.
5. Remove element from filter base.
6. If element needs cleaning, blow out with air. Replace if needed.
Purchase replacement parts from your local dealer or authorized
service center. Always use identical replacement parts.
7. Place element back in filter base.
8. Reconnect filter top to filter base. While pushing in, rotate clock-
wise 5 degrees.
CAUTION: Risk of unsafe operation. Do not operate without air
inlet filter.
Draining Air tanks (Fig. 1)
WARNING: Risk of unsafe operation. Risk from noise. Air tanks
contain high pressure air. Keep face and other body parts away from
outlet of drain. Use safety glasses when draining as debris can be
kicked up into face. Use ear protection (ANSI S12.6 (S3.19) hearing
protection) as air flow noise is loud when draining.
note: All compressed air systems generate condensate that
accumulates in any drain point (e.g., tanks, filter, aftercoolers,
dryers). This condensate contains lubricating oil and/or substances
which may be regulated and must be disposed of in accordance with
local, state, and federal laws and regulations.
1. Ensure engine ON/OFF switch (C) is in the OFF position.
. Place a suitable container under the drain valve to catch
discharge.
WARNING: Risk of Bursting. 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.
CAUTION: Risk of Property Damage. Drain water from air tank
may contain oil and rust which can cause stains.
3. Grasp black lever on drain valve.
4. Slowly rotate lever to gradually bleed air from air tank.
5. Grasp black lever on other drain valve and rotate to approximately
the same position as the first.
6. When air tank pressure gauge reads 10 PSI (68.9 kPa), rotate
valve to the fully open position.
7. Close drain valve when finished.
