Nozzle
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 all 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 Chemicals
Yellow #4.5 Steam
Your pressure washer is equipped with four high
pressure nozzles. To install a nozzle 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.) 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 nozzle to spray
chemicals onto the cleaning surface.
C.) Squeeze the spray gun trigger. The chemical
injector will draw the chemical into the water stream
D.)
Apply chemicals evenly to the cleaning surface.
Allow the chemicals to react with the dirt, then clean at
high pressure with green nozzle.
E.) Never use more chemical than is necessary to clean
the surface.
F.) If you do not intend on using chemicals, we suggest
removing the chemical injector to obtain maximum
cleaning pressure.
Max chemical ratio is 13:1
