Do not attempt to tamper with the tank safety
valve. Anything loosened from this device could fly
up and hit you. Failure to heed this warning could
result in death or serious personal injury.
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 tank safety
valve has been replaced. Use of the air compressor
in this condition could result in serious personal
injury.
TANK SAFETY VALVE
TO RELEASE AIR
RiNG
To check or replace air filter element,
1. Press in on air filter cap while rotating counter-
clockwise to remove filter cap.
2. Remove air filter element for visual inspection.
Loose debris or minor dust may be removed with
a soft bristle brush or compressed air. Filter
element should be replaced if it is wet, torn or
satu rated.
5. Wipe clean the inside of the filter housing before
replacing air filter.
Check the Tank Safety Valve by performing these
steps:
The tank 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.
1. Turn the air compressor on and allow the tank to
fill. The compressor will shut off when the
pressure reaches the preset maximum.
2. Turn the air compressor off.
3. Pull the ring on the tank safety valve to release
air for three to five seconds.
4. Release the ring. Air must immediately stop
escaping when the ring is released.
Any continued loss of air after releasing the ring
indicates a problem with the tank safety valve.
Discontinue use and seek service before
continued use of the air compressor.
