• Makesure the garden hose is connected to the water
inlet.Check that the high pressure hose is connected to

the spraygun 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. Reapplyasneeded 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 I-2 minutes.

Pressure Washer Rinsing

,_ WARNING! Be extremely careful ifyou must

use the pressure washer from a ladder,scaffolding
or anyother relatively unstable location. Pressure in
a running washer builds as you climb. When you
press the trigger, the recoil from the initialspray
could causeyou to fall. The high pressure spray
could alsocauseyou to fall ifyou are too close to
the cleaningsurface.

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.

• Keepthe spray gun a safedistance from the area you
plan to spray.

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

the surface for damage. If no damageis found, it isokay

to continue rinsing.

• Start at the top of the area to be rinsed, working down

with same overlapping strokes asyou usedfor cleaning.

Automatic Cool Down System

(Thermal Relief)

If you run the engine on your pressure washer for
3-5 minutes without pressingthe trigger on the spray gun,

circulating water in the pump can reach a temperature

between 140-145°E When the water reachesthis

temperature, the automatic cool down system engagesand
cools the pump by discharging the warm water onto
the ground. This system prevents internal damageto the

pump.
