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).
7. Allow detergent to soak in between 3–5 minutes
before washing and rinsing. Reapply as needed to
prevent surface from drying.

Pressure Washer Rinsing

After you have applied detergent, scour the surface
and rinse it clean as follows:
1. Apply safety latch to spray gun.
2. Remove black chemical spray tip from nozzle
extension.
3. Select and install desired high pressure spray tip
following instructions in "How to Use Spray Tips".
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.
Operation
4. Increase (decrease) spray pressure by turning pressure
control knob clockwise (counterclockwise) (Figure 8).
Use lower pressure to wash items such as a car or
boat. Use higher pressure to strip paint and degrease
driveways.
Figure 8 — Pressure Control Knob.
5. Apply high pressure spray to small area and check
surface for damage. If no damage is found, you can
assume it is okay to continue cleaning.
6. Start at top of area to be rinsed, working down with
same overlapping strokes as you 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.
