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.
