Pressure Washer Rinsing

_ ARNING! Beextremely 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 inltiat spray
could causeyou to fall. The high pressure spray
could alsocauseyou to falt if you are too close to
the cleaningsurface.

For Rinsing:

• Slidethe nozzle backward to high pressure, press the

trigger and wait 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 sprayto a small area, then check

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

• Start at the top of the areato 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.
