CHECKING THE SAFETY VALVE

See Figure 5, page 14.
DANGER:
Do not attempt to tamper with the safety valve. Anything
loosened from this device could fly up and hit you. Fail-
ure to heed this warning could result in death or serious
personal injury.
The safety valve will automatically release air if the air tank
pressure exceeds the cut-out pressure. The valve should be
checked before each day of use by pulling the ring by hand.
 Install the battery pack.
 Turn the air compressor on and allow the tank to fill. The
compressor will shut off when the pressure reaches the
cut-out pressure.
 Turn the air compressor off.
WARNING:
Always release all pressure, remove the battery packs,
and allow unit to cool to the touch before cleaning or
making repairs on the air compressor.
WARNING:
Always wear eye protection with side shields marked to
comply with ANSI Z87.1. Failure to do so could result in
objects being thrown into your eyes resulting in possible
serious injury.
WARNING:
When servicing, use only identical replacement parts.
Use of any other parts could create a hazard or cause
product damage.

GENERAL MAINTENANCE

Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, oil, grease, etc.
OPERATION
OPERATION
 Pull the ring on the safety valve to release air for three to
five seconds to allow pressurized air to escape. Release
the ring. The safety release valve must reset and hold
pressure before all compressed air is exhausted from the
tank/pressure vessel.
 Any continued loss of air after performing the above steps
indicates a problem with the safety valve. Discontinue
use and seek service before continued use of the air
compressor.
WARNING:
If air leaks after the ring has been released or if the valve is
stuck and cannot be actuated by the ring, do not use the
air compressor until the safety valve has been replaced.
Use of the air compressor in this condition could result
in serious personal injury.
