7. Remove dipstick/oil plug (H) from plastic bag and

install into pump, tighten securely.	h
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.

OPERATION

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.

2.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.

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.

Nozzle Color	Spray Pattern	Uses	Surfaces*
	0˚	powerful	metal or

3.Adjust the pressure reg­lator on the pump. Turn the pressure reg­lator knob (R) counterclockwise to lower pressure. Once you have finished using your pressure wash­ er, return the pressure reg­lator 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.
