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.
