Turn Water Supply on city water tap only

Operating Instructions

V.) Turn Water Supply ON (city water tap only)

Make sure the hose is not “kinked”. A kinked hose will provide insufficient water supply to the pump and will reduce its life. Make sure the hose remains unkinked after moving the pressure washer.

VI.) Attach Nozzle

Color of Nozzle:	Spray Angle	Used For:
Red	0	Highest Impact
Yellow	15	Tough Stains/
		Stripping
Green	25	General
White	40	Light Cleaning
Black	65	Chemicals

Your pressure washer is equipped with four high pressure nozzles. To install a nozzle pull the collar back and push the nozzle into the coupler. Once the connection is made, pull on the nozzle to assure a tight connection.

WARNING: Make sure the nozzle is correctly inserted. The nozzle may become a projectile if not inserted correctly. Do not attempt to use different types of nozzles that may not fit the coupler.

VIII.) Applying Chemicals

WARNING: Only use NorthStar pressure washer chemicals or chemicals specifically formulated for pressure washers. Follow the chemical manufacturer’s recommendations. Understand all safety precautions and first aid for all chemicals.

NOTE: Your pressure washer is equipped with a low pressure chemical injector. The proper chemical used for the proper application can speed up cleaning jobs tremendously.

A.) Snap the quick couple chemical injector onto the high pressure outlet and high pressure hose and submerge the suction strainer into the chemical solution.

B.) You need to use the low pressure black nozzle to spray chemicals onto the cleaning surface.

C.) The amount of chemical applied can be changed by turning the chemical adjustment knob located on the chemical injector.

D.) Squeeze the spray gun trigger. The chemical injector will draw the chemical into the water stream

E.) Apply chemicals evenly to the cleaning surface. Allow the chemicals to react with the dirt, then clean at high pressure with green nozzle.

F.) Never use more chemical than is necessary to clean the surface.

G.) If you do not intend on using chemicals, we suggest removing the chemical injector to obtain maximum cleaning pressure.

IX.) Start Engine

See the engine manual to start your engine. IMPORTANT: The water must be turned on (or water feed tank filled) before starting. Running the pump dry will cause damage and void the warranty.

Make sure only one ball valve is open. The ball valve that you are not using needs to be closed before starting the engine. Pump cavitation can occur.

WARNING: Do not inhale the exhaust from the engine. Do not point the lance at anyone even if the engine has stopped because there could be a release of water under retained pressure if the spray gun trigger is actuated.
