Application
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.
VI.) Turn the pump switch ON.
1. Make sure the hose is not kinked. A kinked hose
will provide insufficient water supply to the pump and
will reduce its life.
To Clean
WARNING: Wear eye, ear, hand, foot and skin protection at
all times while operating this pressure washer.
DANGER: Do not point the spray wand at yourself or
at any person. Bodily injury may result from water
under high pressure.
IMPORTANT: Your spray gun is equipped with a built-in
trigger safety latch to guard against accidental trigger
actuation and potentially dangerous high pressure spray.
Rotate the safety latch to the locked position when not
spraying.
NOTE: Your pressure washer is equipped with a low
pressure chemical injector. You do not need to use
chemicals for every job, however, the proper chemical used
for the proper application can speed up cleaning jobs
tremendously.
WARNING: Only use North Star 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.
1. Insert chemical suction line and strainer into a
container of detergent.
2. Completely open the chemical control knob located
on the chemical injector.
3. Insert the chemical application nozzle (Black).
4. Turn the chemical control knob to adjust the
chemical concentration. Spray detergent onto the
surface and allow it to soak. Chemicals need time
(dwell time) to work properly. Follow the chemical
manufacturer’s recommendations for dwell time.
5. Change back to high pressure by inserting the
nozzle with the desired spray angle.
6. Hold the lance with two hands, have a sturdy stance.
7. Point lance at dirty surface and squeeze trigger.
8. Wash from the bottom to the top, using side to side
motions. This washes away heavy dirt and allows
the detergent to soak as you work toward the top.
9. Use the width of the spray pattern to wash in a wide
path. Overlap spray paths for complete coverage.
10. The nozzle should be 12” to 24” from the work,
closer for tough areas.
Max Chemical Ratio is 13:1
Caution: Be careful on painted or delicate surfaces,
the pressure may damage the surface if the nozzle is
too close.
11. Small parts should be washed in a basket so the
pressure does not push them away. Larger, light
weight parts should be clamped down.
12. The pressure washer is set to the maximum rated
pressure when it leaves the factory. To change your
pressure, turn the unloader knob found inside the
machine counter clockwise.
