Cleaning and Applying Chemical
IMPORTANT: Use soaps designed specifically for
pressure washers. Household detergents could damage
the pump.
CAUTION
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.
To apply detergent follow these steps:
1. Review spray tip use.
2. Prepare detergent solution as required by manufacturer.
3. Place small filter end of detergent siphoning tube into
detergent container.
CAUTION
Keep the chemical injection tube from coming in contact
with the hot muffler.
• When inserting the filter into a detergent solution bottle,
route the tube so as to keep it from inadvertently contacting
the hot muffler.
4. Make sure black spray tip is installed.
NOTE: Detergent cannot be applied with the high
pressure spray tips (White,Yellow, or Red).
5. Make sure garden hose is connected to water inlet.
Check that high pressure hose is connected to spray
gun and pump and start engine.
6. Apply detergent to a dry surface, starting at lower
portion of area to be washed and work upward, using
long, even, overlapping strokes.
7. Allow detergent to soak in between 3–5 minutes
before washing and rinsing. Reapply as needed to
prevent surface from drying. DO NOT allow detergent
to dry on (prevents streaking).
IMPORTANT: You must flush the chemical injection
system after each use by placing the filter into a bucket of
clean water, then run the pressure washer in low pressure
for 1-2 minutes.
