OPERATING
5. Make sure garden hose is connected to water inlet. Check
that high pressure hose is connected to spray gun and
pump. Turn on water.
6. Start engine following instructions How to Start Your
Pressure Washer.
7. Apply detergent to a dry surface, starting at lower portion of
area to be washed and work upward, using long, even,
overlapping strokes.
8. Allow detergent to "soak in" for 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 detergent siphoning 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.
How to Rinse After Use
Pressure Washer Rinsing
1. Remove black spray tip from nozzle extension.
2. Select and install desired high pressure spray tip following
instructions How to Use Spray Tips.
3. Keep spray gun a safe distance from area you plan to spray.
4. Increase (decrease) spray pressure by turning pressure
control knob (A) clockwise (counterclockwise). Use lower
pressure to wash items such as a car or boat. Use higher
pressure to strip paint and degrease driveways.
5. Apply a high pressure spray to a small area and then check
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 detergent siphoning tube/filter in a bucket full of clean
water.
2. Remove high pressure spray tip from nozzle extension.
3. Select and install black detergent spray tip following

Washer and turn off water supply.
6. ALWAYS point spray gun in a safe direction, press red
button 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.
NOTICE
You must attach all hoses before you start the engine.
• 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.
WARNING
Kickback from spray gun can cause you to fall.
• Operate pressure washer from a stable surface.
• Be extremely careful if you must use the pressure washer from a
ladder, scaffolding, or any other similar location.
• Firmly grasp spray gun with both hands when using high pressure
spray to avoid injury when spray gun kicks back.
WARNING
The high pressure stream of water that this
equipment produces can cut through 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.
• Keep high pressure hose connected to pump and spray gun while
system is pressurized.
• ALWAYS point spray gun in safe direction, press red button and
squeeze spray gun trigger, to release high pressure, every time you
stop engine.
