Monitor infl ation pressure using a tire pressure gauge until the
required pressure is achieved (be sure not to exceed the tire
manufactures maximum tire pressure).
Turn ball-valve to the "closed" position (Fig. 8) when infl ation is

DRAINING THE TANK

See fi gure 12.
To help prevent tank corrosion and keep liquid and vapor
condensate out of the air supply, drain the compressor tank at
the end of each day's use.
To drain the tank:
Holding the compressor by its handle, tilt it in the direction of
the drain valve so that the valve is set in a lower position.
Open the drain valve by rotating it ¼ turn counterclockwise
(fi g. 12).
Keep the unit tilted until all liquid and vapor condensate has
been drained into a suitable container.
NOTE: Condensate is a polluting material; dispose of it in
compliance with local regulations.
Close the drain valve by rotating it ¼ turn clockwise (fi g. 12).
WARNING
If drain valve is clogged, unplug air
compressor, release tank pressure by pulling the safety valve
ring, and contact a qualifi ed repair facility for service.

CHECKING THE SAFETY VALVE

See fi gure 13.
DANGER
Do not attempt to tamper with safety valve.
Anything loosened from this device could fl y up and hit you.
Failure to heed this warning could result in death or serious
personal injury.
The safety valve will automatically release air if the air receiver
pressure exceeds the preset maximum. The valve should be
checked before each day of use by pulling the ring by hand.
Turn the air compressor on and allow the tank to fi ll. The compressor
will shut off when the pressure reaches the preset maximum.
Turn the air compressor off.
Pull the ring on the safety valve (fi g. 13) to release air for
twenty seconds.
