Customer Responsibilities

Check Safety Valve
Drain Tank
Air Filter
Air compressor pump intake and exhaust valves
injuries can occur. Before performing any maintenance or repair, disconnect power source from the
compressor and bleed off all air pressure.
To ensure efficient operation and longer life of the air compressor outfit, a routine maintenance schedule
should be prepared and followed. The following routine maintenance schedule is geared to an outfit 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 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.

To Check Safety Valve

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 oper-
ate 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 pressure is approximate-
ly 20 psi. Release safety valve ring.
5. Drain water from air tank by opening drain valve
(counter-clockwise) on bottom of tank.
drained, water will corrode and weaken the
air tank causing a risk of air tank rupture.

MAINTENANCE

6. After the water has been drained, close the
drain valve (clockwise). The air compressor can
now be stored.
NOTE: If drain valve is plugged, release all air pres-
sure. The valve can then be removed, cleaned, the
reinstalled.

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.
