Generac Portable Products 2,400 PSI 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.
• 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.
