Section 4: Operation
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 chemical solution as required by manufacturer.
3. Pour chemical solution into chemical reservoir labeled
A or B.
NOTE: Each chemical reservoir holds two quarts.
4. Fill other chemical reservoir with a different prepared
solution, as desired.
5. Make sure black ProjectPro™ cleaning detergent
nozzle is installed.
NOTE: Detergent cannot be applied with the high
pressure nozzles (Yellow, Orange or Red).
6. Make sure garden hose is connected to water inlet and
water supply is turned on. Check that high pressure
hose is connected to spray gun and pump; start engine.
7. Rotate chemical shut-off valve on desired chemical
reservoir to “On” position (Figure 20).
8. Apply detergent to a dry surface, starting at lower
portion of area to be washed and work upward, using
long, even, overlapping strokes.
9. 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).
Pressure Washer Rinsing
After detergent is applied, scour the surface and
rinse it clean as follows:
1. Engage trigger lock on spray gun.
2. Make sure both chemical shut-off valves are in “Off”
position.
3. Remove black ProjectPro™ cleaning detergent nozzle
from nozzle extension.
4. Select and install desired ProjectPro™ nozzle, as
described in “How to Use ProjectPro™ Nozzle
System”.
5. Keep spray gun a safe distance from spray surface.
6. Apply a high pressure spray to a small area and then
check the surface for damage. If no damage, proceed to
step 7.
7. Start at top of area to be rinsed, working down with
same overlapping strokes used for cleaning.
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 when gun kicks back.
High pressure spray could cause you to fall if
you are too close to the cleaning surface.
WARNING

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.
• Only one chemical solution should be used at a time to avoid
possible bodily injury and/or property damage.
DO NOT turn on both chemical shut-off valves at the
same time.
