High Pressure Washer
How to Use the Dual Lance and
Adjust Pressure
You now should know how to START your pressure
washer and how to STOP it. The information in this
section will tell you how to adjust the pressure and
apply detergent or any other cleaning chemicals.
IMPORTANT: You must attach all hoses and turn
on the water source fully before you start the engine.
Starting the engine without all the hoses connected
and without the water turned on will damage the
pump.
DANGER! Never put hands in front of
nozzle.
Located on the side of the pump is a pressure con-
trol knob. You can increase and decrease the
pressure of the spray by turning the knob clockwise
or counterclockwise respectively (Figure 10). The
unit has been set to maximum at the factory.
Point the nozzle in a safe direction and squeeze the
trigger to test the pressure. Be careful not to spray
your feet.
For most effective cleaning, keep the spray nozzle
between 8 to 24 inches away from cleaning sur-
face.
If you get spray nozzle too close, especially using
high pressure, you may damage the cleaning sur-
face.
Do not get closer than 8 inches when cleaning tires.
Applying Detergent
IMPORTANT: Use soaps designed specifically for
pressure washers. Household detergents could
damage the pump.
To apply detergent follow these steps:
Turn the valve on the dual lance to low pressure.
Prepare the detergent solution as required by the
job.
Hang the detergent solution on the J hook on the
handle.
Place the small filter end of the chemical injecting
tube into the detergent container .
IMPORTANT: Detergent cannot be applied without
the water source turned on.
Make sure garden hose is connected to water inlet.
Check that high pressure hose is connected to
spray gun and pump (see the ASSEMBLY section),
and start engine.
Apply the detergent to a dry surface, starting from
the bottom and working up to avoid streaking.
Allow the detergent to soak in for 3-5 minutes
before washing and rinsing. Reapply detergent to
prevent surface from drying.
For washing, start at lower portion of area to be
washed and work upward, using long, even, over-
lapping strokes.
CAUTION: Keep the plastic chemical
injecting tube from coming in contact with
the hot muffler. This will damage the plas-
tic tube. When inserting the filter into a
cleaning agent bottle, route the tube so as
to keep it from inadvertently contacting the
hot muffler.
