OPERATION
DRAINING THE TANK
See Figures 10 - 11.
To help prevent tank corrosion and keep moisture out of
the air used, the tank of the compressor should be drained
daily.
A correct use of the drain valve:
■ Verify that the compressor is turned off.
■ Holding the handle, tilt the compressor toward the drain
valve so that it’s set in a lower position.
■ Open the drain valve completely.
■ Keep the compressor tilted (figure 11) until all moisture
has been removed.
■ 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 drain valve is clogged, release all air pressure by
pulling the safety valve. Remove and clean valve, then
reinstall.
Mk WARNING:
Unplug the air compressor and release all air from
the tank before servicing. Failure to depressurize tank
before attempting to remove valve may cause serious
personal injury.
■ Turn off drain valve until completely closed.
CHECKING THE SAFETY VALVE
See Figure 12.
WARNING:
Do not attempt to tamper with 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.
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
fill. The compressor will shut off when the pressure
reaches the preset maximum.
■ Turn the air compressor off.
■ Pull the ring on the safety valve to release air for twenty
seconds.
■ Release the ring. Air must immediately stop escaping
when the ring is released. Any continued loss of air
after releasing the safety valve ring indicates a problem
with the safety valve. Discontinue use and seek service
before continued use of the air compressor.
Mk 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.
