Door Safety Switch

The door closure safety switch is located on the rear of
the machine, to the right of the main electrical panel.
The switch is activated with a push-rod that extends
through the wash chamber.
The switch disconnects power to the water pump and
turntable motor if the wash chamber door is opened
during a wash cycle. The water pump and turntable
motor will not operate if the door is not closed and
latched correctly.

Adjusting the Safety Switch

1. Disconnect power to the machine.
2. Remove the two screws from the rear of the safety
switch cover, and pull the cover free of the switch
assembly.
3. Loosen the adjustment nuts on both sides of the
switch bracket.

4. Adjust the switch accordingly.
5. Tighten the adjustment nuts.
6. Replace the cover.
When properly adjusted, you should hear a slight "click"
as the door latch engages and compresses the door
seal and the door closure safety switch.

Debris Screen

The debris screen is located just below the wash
chamber, and is accessible from the front of the
machine. The debris screen continuously filters debris
particles from the cleaning solution to ensure blockage-
free spray nozzle operation, and also provides a
safeguard against small parts that might accidentally be
washed through from the cleaning chamber.

The frequency at which you must clean the debris
screen depends on machine usage. In general, you
should clean the screen before operating the machine
each day.

NOTE: Never operate the machine without the debris
screen in place and never remove the screen while
the machine is operating. The screen is specially
sized to filter particles that could clog the spray
nozzles or damage the water pump.
Operating the machine without the debris screen in
place could cause spray nozzles to clog or the water
pump to fail.

Air Flow Valve (Optional)

The air flow valve is located on the right rear corner of
the machine. It is a three-way ball valve that controls
the flow of compressed air to the power brush and the
hand detail brush.
