representative.
The compressor should be checked often for any visible problems and the
following maintenance procedures should be performed each time the compressor is
used.

2. Wearing safety glasses, pull the ring on the safety valve to release pressure from
compressor tank. Use your other hand to deflect fast-moving air from being
directed toward your face.

1. Turn compressor off at foot pedal switch.
2. Check air pressure in tank. To properly drain tank of condensation, tank pressure
should be between 20-60 psi. Drain system will not work if there is no pressure in
the tank. If tank pressure is above 60 psi, decrease pressure in tank by pulling the
ring on the safety valve. Burst of air will be audible.

close drain knob by turning fully to the right (clockwise) then remove the drain cup
to dispose of fluid.
4. When fluid stops draining, close drain knob by turning all the way to the right
(clockwise).
5. Lift cup up and pull out to dispose of drained fluid. Reinsert cup, making sure to
secure in place.
