High Pressure Washer
Applying Detergent with the
Adjustable Nozzle
IMPORTANT: Use soaps designed specifically for
pressure washers. Household detergents could
damage the pump.
IMPORTANT: You must attach all hoses before you
start the engine. Starting the engine without all the
hoses connected and without the water turned ON
will damage the pump.
To apply detergent follow these steps:
Review the use of adjustable nozzles on Page 10.
Prepare the detergent solution as required by the
job.
Hang the detergent solution on hook of the wire-
form on the handle as shown (Figure 13).
Place small filter end of the chemical injection tube
into the detergent container.
Slide the adjustable nozzle forward to low pressure
mode. Detergent cannot be applied with nozzle in
high pressure position.
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 ASSEMBLY), and start
engine.
Apply 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.
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
injection 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.
Pressure Washer Rinsing
WARNING: Be extremely careful if you
must use the pressure washer from a
ladder, scaffolding or any other relatively
unstable location. Pressure in a running
washer builds as you climb. When you
press the trigger, the recoil from the initial
spray could force you to fall. The high
pressure spray could also force you to fall
if you are too close to the cleaning surface.
For Rinsing:
Slide nozzle backward to high pressure and wait for
detergent to clear.
Keep the spray gun a safe distance from the area
you plan to spray.
Apply a high pressure spray to a small area and
then check the surface for damage. If no damage
is found, you can assume it is okay to continue
cleaning.
Start at top of area to be rinsed, working down with
same overlapping strokes as you used for cleaning.
Note: You can also stop detergent from flowing by
simply removing the chemical injection tube from the
bottle.
Automatic Cool Down System
(Thermal Relief)
If you run the engine on your pressure washer for 3-5
minutes without pressing the trigger on the spray gun,
circulating water in the pump can reach a tempera-
ture between 140145°F. When the water reaches
this temperature, the automatic cool down system
engages and cools the pump by discharging the
warm water onto the base of the unit. This system
prevents internal damage to the pump.

of cleaning solution.
