MAINTENANCE
Unit cycles
automatically when
power is on. When performing
maintenance, you may be exposed
to voltage sources, compressed air,
or moving parts. Personal injuries
can occur. Before performing any
maintenance or repair, disconnect
power source from the compressor
and bleed "Off" all air pressure.
NOTE: See Operation section for the
location of controls.
To Check Safety Valve
Risk of Bursting.
If the safety valve
does not work properly, over-
pressurization may occur, causing
air tank rupture or an explosion.
Risk from Flying
Objects. Always
wear certified safety equipment:
ANSI Z87.1 eye protection (CAN/CSA
Z94.3) with side shields
1. 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.
To Drain Tank
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 ANSI Z87.1 eye protection
(CAN/CSA Z94.3) 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.
1. Set the On/Auto/Off lever to "Off".
2. Pull the regulator knob out and
turn counterclockwise 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 approximately 20
psi. Release safety valve ring.
5. Drain water from air tank by
opening drain valve on bottom of
tank.
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.
Risk of Property
Damage. Drain
water from air tank may contain oil
and rust which can cause stains.
6. After the water has been drained,
close the drain valve. The air
compressor can now be stored.
NOTE: If drain valve is plugged,
release all air pressure. The valve
can then be removed, cleaned, the
reinstalled.
