Check for air leaks* X
Clean compressor exterior
* 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.
Checking Safety Valve (Fig. 1)
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. Before starting
compressor, pull the ring on the safety valve to make sure that the
safety valve operates freely. NOTE: Ring may be difficult to pull
when air tank pressure is at 0 PSI (0 kPa). 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. outlet tube, pump head,
and surrounding parts are very hot, do not touch. Allow compressor
to cool prior to servicing.
1. Ensure the On/Off switch (L) is in the OFF position.
2. Allow unit to cool.
3. Remove air filter from unit.
4. Carefully pry 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. Snap filter top to filter base.
9. Reassemble air filter to unit. Ensure exhaust outlet points down.
CAUTION: 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 safety glasses [ANSI Z87.1 (CAN/CSA Z94.3)]
when draining as debris can be kicked up into face. Use ear protection
[ANSI S12.6 (S3.19)] 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 On/Off switch is in the OFF position.
2. Lift front of compressor into an inclined position so drain valve
(M) is at the lowest point (this will assist in removing moisture,
dirt, etc. from air tanks).
