USING THE AIR COMPRESSOR
See Figure 4, page 14.
WARNING:
Risk of bursting. Do not adjust pressure regulator
knob to result in output pressure greater than marked
maximum pressure of attachment and/or the item being
inflated. Never use at pressure greater than 120 psi. Fail-
ure to heed this warning could result in possible serious
personal injury.
WARNING:
Air powered tools may require more air consumption
than this air compressor is capable of providing. Check
the tool manual to avoid damage to the tool or risk of
personal injury.
 Ensure that the Auto On/Off switch is in the OFF position
and the battery pack is not installed.
 Attach air hose following the instructions in Connecting/
Disconnecting Air Hose (hose not provided).
 Attach 1/4 in. NPT quick-connect air fitting to the
accessory or tool you intend to use.
 Insert the other end of the quick-connect air fitting to the
quick coupler on the open end of hose.
 Install the battery pack.
 Move the Auto On/Off switch to the Auto On position.
 Set the amount of air pressure desired using the pressure
regulator knob. Pull the knob out, then turn clockwise to
increase or counterclockwise to decrease the air pressure
through the hose. When the desired pressure is set, push
the knob back in to lock.
NOTE: Always use the minimum amount of pressure
necessary for your application. Using a higher pressure
than needed will drain air from the tank more rapidly,
cause the unit to cycle on more frequently, and reduce
battery run time between charges.
 Following all safety precautions in this manual and the
manufacturer's instructions in the air tool manual, you
may now proceed to use your air-powered tool.
NOTE: The air compressor will shut off during an electri-
cal overload. To reset the internal overload switch, turn
off the air compressor and allow the unit to cool. Remove
and then reinstall the battery packs before resuming
operation.
 When finished, always drain the tank, turn the unit off,
and remove the battery packs. Never leave the unit on
and/or running unattended.

OPERATION
DRAINING THE TANK
See Figures 5 - 6, page 14.
To help prevent tank corrosion and keep moisture out of the air
used, the air tank of the compressor should be drained daily.
To drain:
 Turn the air compressor off and remove the battery packs.
 Pull the ring on the safety valve to release air until tank
pressure gauge reads less than 20 psi.
 Release the ring.
 Turn the drain valves 90° counterclockwise to the ON
(open) position.
 Tilt tank to drain moisture from tank into a suitable
container.
NOTE: Condensate is a polluting material and should be
disposed of in compliance with local regulations.
 If a drain valve is clogged, release all air pressure, remove
and clean valve, then reinstall.
WARNING:
Turn off the air compressor, remove battery packs, and
release all air from the tank before servicing. Failure to
depressurize tank before attempting to remove valve
could cause serious personal injury.
 Turn the drain valves 90° clockwise to the OFF (closed)
position.
WARNING:
RISK OF BURSTING. All compressed air tanks have a
limited lifespan. The lifespan can be affected by a num-
ber of factors, including operating conditions of the air
compressor, proper maintenance of the tank, and unau-
thorized repairs and modifications. Since deterioration of
the tank can occur internally with no outward signs, the
air tank(s) on this compressor MUST be removed from
service by the end of the year shown on the data label.
Use of the air compressor after this date increases the
risk of an air tank rupture, which could result in serious
personal injury.
