Applying Detergent with the
Adjustable Nozzle
IMPORTANT: Use soaps designed specifically for
pressure washers.
Household detergents could
damage the pump.
To apply detergent follow these steps:
Review the use of adjustable nozzles on Page 11.
Prepare the detergent as required on the bottle.
Hang the detergent solution on hook of the
wireform on the handle as shown (Figure 13).
Place small filter end of the chemical injection tube
into the detergent container (Figure 13).
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,
overlapping strokes.
CAUTION: Keep the plastic chemical
injection tube from coming in contact with
the hot muffler. This will damage the
plastic 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.
Note
: You can also stop detergent from flowing by
simply removing the chemical injection tube from the
bottle.
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
the same overlapping strokes you used for
cleaning.
For most effective cleaning, keep spray nozzle
between 8 to 24 inches away from cleaning
surface.
If you get spray nozzle too close, especially using
high pressure mode, you may damage the cleaning
surface.
Do not get closer than 6 inches when cleaning
automobile tires.
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
temperature 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.
