detergent.
Figure 23 – Install Siphoning Tube
NOTE:
Make sure the filter remains fully submerged in detergent
while applying detergent.
NOTE:
Contact with the hot muffler can damage detergent siphoning
tube.
• When inserting the siphon into a detergent solution bottle, route the
tube so as to keep it from inadvertently contacting the hot muffler.
6. Make sure black detergent nozzle is installed.
NOTE:
Detergent cannot be applied with the high pressure nozzle
(Green or Red). Only use the Black nozzle with detergent.
7. Confirm set-up instructions have been followed.
NOTE:
You must attach all hoses before you start the engine.
• Starting the engine without all the hoses connected and without the
water turned ON will damage the pump.
• Damage to equipment resulting from failure to follow this instruction
will void warranty.
8. Start engine following instructions How to Start Your Power
Washer.
9. Apply detergent to a dry surface, starting at lower portion
of area to be washed and work upward using long, even,
overlapping strokes.
10. Allow detergent to "soak in" for 3-5 minutes before washing
and rinsing. Reapply as needed to prevent surface from
drying. DO NOT allow detergent to dry on surface being
cleaned (prevents streaking).
IMPORTANT: You must flush the detergent siphoning system after
each use by placing the filter into a bucket of clean water, then run
the power washer in low pressure for 1-2 minutes.
POWER WASHER RINSING

animals and plants. Squeeze trigger to flush any remaining
chemical from system.

ladder, scaffolding, or any other similar location.
• Firmly grasp spray gun with both hands when using high pressure
spray to avoid injury when spray gun kicks back.
5. Apply a high pressure spray to a small area and then check

overlapping strokes as you used for cleaning.
