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 (Fig. E)

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.
Before starting compressor, pull the ring on the safety

To Drain Tank (Fig. E, F)

WARNING: Risk of Unsafe Operation. 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.

WARNING: Risk from noise. Always wear proper
hearing protection during use. Under some conditions
and duration of use, noise from this product may
contribute to hearing loss.
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.

WARNING: 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.
NOTICE: Risk of Property Damage. Drain water
from air tank may contain oil and rust which can
cause stains.

bottom of tank.
8. 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
by connecting a tool the the airline and operating it until
tank pressure is zero psi. The valve can then be removed,
cleaned, the reinstalled.
