lowed. The following routine maintenance schedule is geared to an

outfit in a normal working environment operating on a daily basis.

If necessary, the schedule should be modified to suit the condi-

tions under which your compressor is used. The modifications will

depend upon the hours of operation and the working environment.

Compressor outfits in an extremely dirty and/or hostile environment

will require a greater frequency of all maintenance checks.

NOTE: See Operation section for the location of controls.

Checking Safety Valve (Fig. 1)

WARNING: Hot surfaces. Risk of burn. Tubes, pump head, and

surrounding parts are very hot, do not touch (see the Hot Surfaces

identied 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 ying objects. Always wear certied

safety equipment: ANSI Z87.1 eye protection (CAN/CSA Z94.3) with

side shields.

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 (Fig. 1)

WARNING: Hot surfaces. Risk of burn. Tubes, pump head, and

surrounding parts are very hot, do not touch (see the Hot Surfaces

identied in Fig. 2). 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. Ensure Auto/Off switch (B) is in the OFF Position.

2. Allow unit to cool.

3. Remove the 3 phillips screws and washers from the pump

head.

4. Remove the small plate, being careful not to drop anything on

the exposed valves.

5. Carefully lift out the air filter and screens. NOTE: The screen

edges are sharp.

6. Place cleaned or new air filter between the screens and insert

back into grooves. Refer to the Replacement Parts under

Service.

7. Place the plate back onto the pump head, insert the screws

and washers, tighten the screws.

CAUTION: Risk of unsafe operation. Do not operate without air

lter.

Draining Air Tank (Fig. 3)

WARNING: Risk of unsafe operation. 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 ow noise is loud when draining.

NOTE: All compressed air systems generate condensation that accu-

mulates 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. Set the Auto/Off switch to “Off”.

2. Pull ring on safety valve allowing air to bleed from the tank until

tank pressure is approximately 20 psi. Release safety valve

ring.

3. Drain water from air tank by opening drain valve (counterclock-
