Applying Detergent

CAUTION: Chemicals can cause bodily injury, and/or
property damage.
• NEVER use caustic liquid with pressure washer.
• Use ONLY pressure washer safe detergents/soaps. Follow all
manufacturers instructions.
To apply detergent, follow these steps:
1. Review use of spray tips.
2. Prepare detergent solution as required by job.
3. Place small filter end of detergent siphoning tube into
detergent container.
NOTE: Make sure the filter is fully submerged in detergent
while applying detergent.
NOTICE: Contact with the hot muffler can damage detergent
siphoning tube.
• When inserting the siphon into a detergent solution bottle, route
the tube so as to keep it from inadvertently contacting the hot
muffler.
4. Make sure black spray tip is installed.
NOTE: Detergent cannot be applied with the high pressure
spray tips (Green or Red).
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.
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.
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.

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.
4. 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.
5. 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
instructions How to Use Spray Tips.
4. Flush for 1-2 minutes.
5. Shut off engine following instructions How to Stop
Pressure Washer and turn off water supply.
6. ALWAYS point spray 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.
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.

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.
