5. Make sure garden hose is connected to water inlet.
Check that high pressure hose is connected to spray
gun and pump; 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. DO NOT allow
detergent to dry on (prevents streaking).

before washing and rinsing. Reapply as needed to
prevent surface from drying.

2. Remove black chemical spray tip from nozzle
extension.
3. Select and install desired high pressure spray tip
following the instructions in "How to Use Spray Tips".
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 if gun kicks back.
5. Increase or decrease spray pressure by turning
pressure control knob counterclockwise or clockwise

6. Apply high pressure spray to small area and then check
surface for damage. If no damage is found, you can
assume it is okay to continue cleaning.
7. Start at top of area to be rinsed, working down with
same overlapping strokes as 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 low pressure spray tip.
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.
