Pressure Washer Operating Features - PowerWasher PW2623C Instruction Manual

Thermal Relief Valve
(p):
When
temperature inside the
pump rises too high, this
valve will open and
release a gush of water in an effort to
lower the temperature inside the pump.
The valve will then close.
Detergent Injection System: Mixes
cleaners or cleaning solvents with the
water to improve cleaning effectiveness.
Water Supply: All pressure washers
must have a source of water. The
minimum requirements for a water
supply are 20 psi and 5 Gallons Per
Minute. If your water source is a well,
the garden hose length can only be
30 ft. (9 m) max.
WARNING:
possibility of contamination always
protect against
connected to a potable water system.

pRESSURE ADJUSTMENTS
The pressure setting is preset at the
factory to achieve op ti mum pres sure
and cleaning. If you need to lower the
pres sure, it can be accomplished by
these meth ods.
1. back away from the sur face to
be cleaned. The further away you
are, the less the pressure will be on
the surface to be cleaned.
2. Rotate the nozzle at the end of
the variable fan spray wand to
widen the fan spray. The wider
fan spray will minimize the pressure
on the surface to be cleaned.
NOTICE: DO NOT attempt to increase
pump pressure. A higher pressure
setting than the factory set pressure
may damage pump.

hOW TO USE SpRAY WAND
(fIG. 6–8)
Your pressure washer is equipped with
a variable fan spray wand with both
high and low pressure settings. The
high pressure setting is for cleaning
and rinsing, the low pressure setting
is for applying chemicals or cleaning
solutions to surfaces.
DANGER: Risk of fluid injection.
Do not direct discharge stream
toward persons, unprotected skin,
eyes or any pets or animals. Serious
injury will occur.
For high pressure operation, pull back
the nozzle of the variable fan spray
wand as shown.

The nozzle at the end of the variable fan
spray wand can be rotated to change
the high pressure spray pattern from a
jet stream to a wide angle fan spray, as
shown. Markings have been placed on
the nozzle to help you select the spray
pattern.
