Automatic Cool Down System; Pressure Washer Rinsing - Generac Portable Products 2700PSI Owner's Manual

• Place the small filter end of the detergent siphoning tube
into the detergent container.
CAUTION!
Keep the chemical injection tube from
coming in contact with the hot muffler.
• Make sure the black nozzle is installed.
NOTE: Detergent cannot be applied with the high
pressure nozzles (White, Green, Yellow, or Red).
• 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 and start the engine.
• Apply the detergent to a dry surface, starting at lower
portion of area to be washed and work upward, using
long, even, overlapping strokes.
• Allow the detergent to soak in between 3–5 minutes
before washing and rinsing. Reapply as needed to prevent
surface from drying. Do Not allow the detergent to dry
on (prevents streaking).
IMPORTANT: You must flush the chemical injection
system after each use by placing the filter into a bucket of
clean water, then run the pressure washer in low pressure
for 1-2 minutes.

Pressure Washer Rinsing

WARNING!
Be extremely careful if you must
use the pressure washer from a ladder, scaffolding
or any other relatively unstable location. Hose
water pressure builds as you climb. When you press
the trigger, the recoil from the initial spray can be
very strong. The high pressure spray could cause
you to fall if you are too close to the cleaning
surface.
Generac 2,700 PSI Pressure Washer
After you have applied detergent, scour the surface
and rinse it clean as follows:
• Apply safety latch to spray gun.
• Remove the black chemical nozzle from the nozzle
extension.
• Select and install the desired high pressure nozzle
following the instructions "How to Use the Nozzles" on
page 10.
• 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 rinsing.
• Start at the top of the area to be rinsed, working down
with same overlapping strokes as you used for cleaning.

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. At this temperature, the system
engages and cools the pump by discharging the warm
water onto the ground. This system prevents internal
damage to the pump.
