(about ¼).
10. Set the center operation mode switch to the “NORMAL” position.
11. Set the CHEMICAL SWITCH valve to the “ON” position.
12. Set the TEMPERATURE CONTROL VALVE on the side of the machine to the
“CLOSED” position.

the key and it will spring back to the “ON” position. Push in the choke T-
handle.
14. Allow engine to warm up by idling for 5 minutes.
15. Press red button and pull out throttle control slowly to attain desired operating
speed, then release red button. Fine tuning of engine speed setting can be ac-
complished by turning the throttle control knob either clockwise (reduces speed)
or counterclockwise (increases speed). Do not exceed 3300 rpm. Only run at the
speed necessary to accomplish the cleaning activity. White Magic recommends
operation at 2000-2500 rpm for single wand cleaning, 2500-2800 rpm for dual
wand operation.
16. Flip the PUMP SWITCH to the “ON” position.
17. Depress the cleaning tool trigger and observe the water pressure gauge reading.
The desirable pressure is 500 psi. To adjust, turn the unloader handle clockwise
to increase pressure and counterclockwise to decrease pressure.
18. Set the output water temperature by adjusting the TEMPERATURE CONTROL
KNOB which is located on the upper face panel.
19. Depress the cleaning tool trigger and monitor the face panel chemical flow meter
reading. Adjust as desired by rotating chemical adjust valve counterclockwise to
increase flow and clockwise to decrease flow. If air is in flow meter or lines, or
no flow is indicated, pulse pump may need to be primed. (Refer to pulse pump
priming)
20. Proceed to your cleaning task by starting to clean at the point furthest
away from the vehicle and working back toward it.
