Cleaning and Applying Detergent
IMPORTANT: Use detergents designed specifically
for pressure washers. Household detergents could
damage the pump.
To apply detergent follow these steps:
1. Review ProjectPro™ nozzle use.
2. Prepare detergent solution as required by manufacturer.
3. Place small filter end of detergent siphoning tube into
detergent container.
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. Apply trigger lock to 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.
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. Attach black cleaning detergent nozzle.
3. Flush for 1-2 minutes.
4. Shut off engine.
IMPORTANT: Simply shutting OFF engine will not
release pressure in the system. When the engine has
shut down, squeeze the trigger on the spray gun to
relieve the pressure in the hose.
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.
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 if gun kicks back.
High pressure spray could cause you to fall if
you are too close to the cleaning surface.
WARNING
CAUTION
When inserting the filter into a detergent solution bottle,
route the tube so as to keep it from inadvertently contacting
the hot muffler.
Keep the chemical injection tube from coming in contact
with the hot muffler.
Section 4: Operation
CAUTION
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.
You must attach all hoses before you start the engine.
