IV.) Attach High Pressure Hose
Your pressure washer hose is equipped with quick
couplers. Simply pull the collar back and push the
coupler onto the nipple. Make sure the collar slides over
the ball bearings. Once the connection is made, pull on
the hose to assure a positive connection.
V.) Turn Water Supply ON
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.) Squeeze Trigger
Squeeze the trigger until a steady flow of water sprays
out the nozzle. Make sure all the air is out of the hoses
before running the pressure washer. This step is very
important, it will prolong the pump’s life. NEVER run the
pump dry.
VII.) 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 Applying
Chemicals
Your pressure washer is equipped with five nozzles. To
install a nozzle simply pull back the collar 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.) Place the chemical injection hose onto the chemical
injector hose barb and submerge the suction strainer
into the chemical solution.
B.) You need to use the 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, and then clean
at high pressure with green nozzle.
F.) Never use more chemical than is necessary to clean
the surface.
IX.) Start Engine
*Refer to the engine manual to start your
engine.
IMPORTANT: The water must be turned on before
starting. Running the pump dry will cause damage
and void the warranty.
IMPORTANT: Make sure the fuel shutoff valve
located under the fuel tank is in the ON position.
WARNING: Check that there are no leaks in the
vicinity of the pump before starting engine.
Once the engine is started, begin cleaning. If the engine
doesn’t start on the first pull, pressure may build up in the
pump. Relieve the pump pressure by squeezing the
spray gun trigger. This will make starting easier.
