• If you get the 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.
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 container on the hook
provided on the handle (Figure 15).
• Place small filter of the detergent siphoning tube into the
detergent container.
CAUTION! Keep the plastic siphon tube from
coming in contact with the hot muffler as this will
damage the tube. When inserting the filter into a
cleaning agent container, 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.

• Make sure garden hose is connected to water inlet.
Check that high pressure hose is connected to spray gun
and pump.
• Start engine and attach nozzle extension.
• 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. 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 nozzle backward to high pressure and wait for
detergent to clear.
NOTE: You can also stop detergent from flowing by
simply removing siphon tube from bottle.
• Keep the spray gun a safe distance from the area you
plan to spray.
• Apply the high pressure spray to a small area and 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 downward
with the same overlapping strokes as you used for
applying chemical.
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.

clogged or replace if screen is damaged.
Check High Pressure Hose
A high pressure hose can develop leaks from wear, kinking,
or abuse. Inspect the hose each time before using it. Check
for cuts, leaks, abrasions or bulging of cover, damage or
movement of couplings. If any of these conditions exist,
replace hose immediately.
DANGER! Water spraying from a leak is capable
of injecting material into skin. Inspect hose each
time before using it. Never repair a high pressure
hose. Replace it with another hose that meets the
maximum pressure rating of your pressure washer.
Check Detergent Siphon Tube
Examine the filter on the detergent siphon tube and clean if
clogged. Tube should fit tightly on barbed fitting. Examine
tube for leaks or tears. Replace the filter or tube if either is
damaged.
Check Gun and Nozzle Extension
Examine hose connection to spray gun and make sure it is
secure. Test trigger by pressing it and making sure it springs
back into place when you release it. Put safety latch in ON
position and test trigger. You should not be able to press
