Cleaning and Applying Detergent
IMPORTANT: Use detergents 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 ProjectPro™ nozzle use.
2. Prepare detergent solution as required by
manufacturer.
3. Place 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 ProjectPro™ cleaning detergent
nozzle is installed.
NOTE: Detergent cannot be applied with the high
pressure nozzles (Yellow, Orange 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.
Pressure Washer Rinsing
For Rinsing:
1. Engage trigger lock on spray gun.
2. Remove black cleaning detergent nozzle from
nozzle extension.
3. Select and install desired high pressure nozzle
following instructions "How to Use ProjectPro™
Nozzle System".
4. Keep spray gun a safe distance from the area you
plan to spray.
WARNING
High pressure spray could cause you to fall
if you are too close to the cleaning surface.
• Keep spray nozzle between 8 to 24 inches away from
cleaning surface.
• Operate this unit on a stable surface.
• Be extremely careful if you must use the pressure
washer from a ladder, scaffolding or any other relatively
unstable location.
• Firmly grasp spray gun with both hands when using high
pressure spray to avoid injury when gun kicks back.
5. Apply a high pressure spray to a small area and
then check the surface for damage. If no damage is
found, you can assume it is okay to continue rinsing.
6. Start at top of area to be rinsed, working down with
same overlapping strokes as you used for cleaning.
Cleaning Detergent Siphoning Tube
If you used the detergent siphoning tube, you must
flush it with clean water before stopping the engine.
1. Place chemical injection siphon/filter in a bucket
full of clean water.
2. Engage trigger lock on spray gun.
3. Attach black cleaning detergent nozzle.
4. Flush for 1-2 minutes.
5. Shut off engine.
6. ALWAYS point gun in a safe direction and
squeeze spray gun trigger to release retained high
water pressure.
IMPORTANT: Spray gun traps high water pressure,
even when engine is stopped and water is disconnected.
Automatic Cool Down System
(Thermal Relief)
If you run the engine on your pressure washer for
3-5 minutes without pressing the trigger on the spray
gun, circulating water in the pump can reach
temperatures above 125°F. The system engages to
cool the pump by discharging the warm water onto
the ground.
