1800 PSI Pressure Washer

WARNING!

The turbo nozzle produces an

extremely high pressure spray which is capable of
removing paint and cutting holes through surfaces if
held too close. Always make sure the surface you
will clean will not be damaged by the high pressure
spray by testing in a hidden area.

NOTE: You cannot apply detergent with the turbo nozzle.

Applying Detergent with the

Adjustable Nozzle

CAUTION!

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.

IMPORTANT: Use soaps designed specifically for
pressure washers. 
Household detergents could damage
the pump.

To apply detergent, follow these steps:

• Review the use of adjustable nozzles.

• Prepare detergent solution as required by the

manufacturer.

• Place the small filter end of the detergent siphoning tube

into the detergent container.

CAUTION!

Keep the detergent siphoning tube from

coming in contact with the hot muffler.

• Slide the adjustable nozzle forward to low pressure

mode. Detergent cannot be applied with the nozzle in
high pressure position.

• Make sure the garden hose is connected to the water

inlet. Check that the high pressure hose is connected to
the spray gun and the pump. Start the engine.

• Apply the detergent to a dry surface, starting at lower

portion of area to be washed and work upward, using
long, even, overlapping strokes.

• Allow the detergent to “soak in” for 3-5 minutes before

washing and rinsing. Reapply as needed to prevent
surface from drying. Do Not allow the detergent to dry
on (prevents streaking).

IMPORTANT: You must flush the chemical injection
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.

Pressure Washer  Rinsing

WARNING!

Be extremely careful if you must use

the pressure washer from a ladder, scaffolding or any
other relatively unstable location. Pressure builds as
you climb in a running washer.When you press the
trigger, the recoil from the initial spray could cause
you to fall.The high pressure spray could also cause
you to fall if you are too close to the cleaning surface.

For Rinsing:

• Slide the nozzle backward to high pressure and press the

trigger. It will take a few seconds for the detergent to
clear.

NOTE: You can also stop detergent from flowing by simply
removing detergent siphon tube from bottle.

• Keep the spray gun a safe distance from the area you

plan to spray.

• Apply a high pressure spray to a small area, then check

the surface for damage. If no damage is found, it is okay
to continue rinsing.

• Start at the top of the 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 a temperature between 125°–155°F.
When the water reaches this temperature, the automatic cool
down system engages and cools the pump by discharging
the warm water onto the ground. 
This system prevents
internal damage to the pump.
