install into pump, tighten securely.
note: The shipping plug must be removed and
replaced with the dipstick/oil plug before operat-
ing pressure washer.
WARNING: Risk of bursting. Use a tire pressure
gauge to check the tires pressure before each use and while inflating
tires; see the tire sidewall for the correct tire pressure.
note: Air tanks, compressors and similar equipment used to
inflate tires can fill small tires similar to these very rapidly. Adjust
pressure regulator on air supply to no more than the rating of the
tire pressure. Add air in small increments and frequently use the
tire gauge to prevent over inflation.

Pressure Adjustments
The pressure setting is preset at the factory to achieve optimum pres-
sure and cleaning. To lower the pressure, follow these instructions.
1. Back away from the surface to be cleaned. The further away you
are, the less the pressure will be on the surface to be cleaned.
. Change to the 40˚ nozzle (white). This nozzle delivers a less
powerful stream of water and a wider spray pattern. Refer to
spray Wand nozzles.
3. Adjust the pressure regulator on the
R pump. Turn the pressure regulator knob (R)
counterclockwise to lower pressure. Once
you have finished using your pressure wash-
er, return the pressure regulator to its origi-
nal position by turning it clockwise.
cAutIoN: Do not try to turn pressure regula-
tor knob past the built-in stop or damage to the
pump will result.
Spray Wand nozzles (Fig. 1)
The nozzles for the spray wand are stored in the nozzle holder (G) on
the panel assembly (F). Colors on the panel identify nozzle location
and spray pattern. Refer to the following chart to choose the correct
nozzle for the job to be performed.
