* To check for air leaks apply a solution of soapy water around
joints. While compressor is pumping to pressure and after
pressure cuts out, look for air bubbles to form.
** The pump oil must be changed after the first 20 hours or operation.

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.
WARNING: Risk from flying objects. Always wear certified safety
equipment: ANSI Z87.1 eye protection (CAN/CSA Z94.3) with side
shields when using the compressor.
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.
2. 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 need-
ed. 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
clockwise 5 degrees.
NOTICE: Risk of unsafe operation. Do not operate without air
inlet filter.
Draining Air Tank (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 eye protection [ANSI Z87.1 (CAN/
CSA Z94.3)] when draining as debris can be kicked up into face.
WARNING: Risk from noise. Use ear protection [ANSI S12.6
(S3.19)] as air flow noise is loud when draining.
