Pressure Washer Rinsing
Wash and Rinse Surface
This pressure washer permits regulation of output water
pressure by varying the engine speed.The throttle control
lever found on the front of the engine may be set, as shown
in Figure 17:
After you have applied detergent, scour the surface
and rinse it clean as follows:
1. Engage safety latch on spray gun.
2. Remove black chemical nozzle from nozzle extension.
3. Select and install desired high pressure nozzle following
instructions “How to Use Spray Tips” on page 12.
4. Keep spray gun a safe distance from the area you plan
to spray.
5. Adjust spray pressure by sliding throttle control lever left
or right, as shown in Figure 13 on page 11.
6. 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.
7. 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 detergent siphoning tube/filter in a bucket full of
clean water.
2. Engage safety latch 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.
• 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.

while system is pressurized.
• ALWAYS point gun in safe direction and squeeze spray gun
trigger, to release high pressure, every time you stop engine.
Engage trigger lock when not in use.
The high pressure stream of water that this
equipment produces can pierce skin and its
underlying tissues, leading to serious injury and
possible amputation.
Spray gun traps high water pressure, even when
engine is stopped and water is disconnected,
which can cause injury.
