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.
• Prepare the detergent solution as required by the
job.
• Hang the detergent solution on the hook of the
wireform attached to the handle, as shown in
Figure 15.
• Remove the detergent siphoning tube from the clip
on the handle.
• Place the filter end of the detergent siphoning tube
into the detergent container.
CAUTION! Keep the detergent siphoning tube
from coming in contact with the hot muffler. This
will damage the plastic tube. When inserting the
filter into a cleaning solution 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 the nozzle
in high pressure position.
• Make sure the garden hose is connected to the
water inlet. Check that the high pressure hose is
connected to the spray gun and the pump (see
“Connect Hose and Water Supply to Pump”,
page 7). Start the engine.
• Apply detergent to a dry surface, starting from the
bottom and working up.
• Allow the detergent to “soak in” for 3-5 minutes
before washing and rinsing. Reapply as needed to
prevent surface from drying.
• 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 cause you to fall. The
high pressure spray could also cause you to fall
if you are too close to the cleaning surface.
For Rinsing:
• Slide the nozzle backward to high pressure, press
the trigger and wait for the detergent to clear.
NOTE: You can also stop detergent from flowing by
simply removing detergent siphoning tube from bottle.
• Keep the spray gun a safe distance from the area
you plan to spray.
• Apply a high pressure spray to a small area, then
check the surface for damage. If no damage is
found, it is okay to continue cleaning.
• Start at the top of the area to be rinsed, working
down with same overlapping strokes as you used for
washing and applying detergent.
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 140–145°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.
