Following is information concerning the four nozzles pro-
vided with your pressure washer.
NOTE: The force of the spray on the surface you are
cleaning increases as you move closer to the surface.
0° High Pressure (Red): The water stream discharged is
very aggressive. Use with extreme caution to prevent damage
to the surface being cleaned or injury to persons or animals.
15° High Pressure (Yellow): This is the nozzle used for
most cleaning applications. It provides wide coverage and a
powerful water stream.
40° High Pressure (White): This nozzle is used for
cleaning with a wider coverage over a larger area with a
powerful water stream.
65° Low Pressure (Black): Provides low pressure spray
and a wide coverage. Used primarily when operating the
chemical injector to apply chemicals.
Replacing the Nozzles
To replace a nozzle with a different nozzle, an easy quick
connect has been added to the end of the wand. With the
handle in the locked close position and the wand pointing
away from the user. Pull back on the quick connect fitting and
pull out the nozzle and replace with desired nozzle.
The pump is shipped with a shipping plug, this will need
to be replaced with the vent plug that is supplied.
PRESSURE ADJUSTMENT
The pressure is adjustable by turning the pressure adjust-
ment knob located on the pump of the pressure washer. The
knob must be set at the extreme clockwise position for maxi-
mum pressure and turned several turns counter clockwise for
maximum pressure.
NOTE: With the pressure adjustment knob turned to
the maximum pressure position (clockwise), the pump
pressure may exceed the rated pressure of the machine
which could over load the engine. Adjust the knob counter
clockwise to reduce the pressure and lower the power
requirements of your pressure washer pump.
The pressure may also be regulated by the use of the
engine speed.
