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 11.
Prepare the detergent solution as required by the
job.
Hang the detergent solution on hook of the wireform
on the handle (Figure 15).
Place small filter of the clear, detergent siphoning
tube into the detergent container.
CAUTION!
Keep the plastic injector 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.
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. Start engine.
Apply detergent to a dry surface, starting from the
bottom and working up.
Allow the detergent to soak in between 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.
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 an 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 siphon from bottle.
Automatic Cool Down System
(also known as 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 ground.
This system prevents
internal damage to the pump.
