Operation Instructions

I.) Pre-Operation
  • A.) Position the machine for easy access to all controls.
  • B.) Position the machine on a solid surface, with less than a three degree slope, and so it is protected from external damage.
  • C.) Make sure ambient lighting is sufficient for the surface you are cleaning to be seen with ease. Use artificial light if needed.
  • D.) Check hoses, fittings, wand, trigger gun and electrical cords for signs of wear, cracks and looseness, and replace as required.
  • E.) Check and clean the nozzle orifice.
  • F.) Check and clean the water inlet screen and filter.
  • G.) Read entire manual, especially the important safety instructions listed on page 2.
  • H.) Check and maintain proper oil levels in the pump.
II.) Check Your Water Supply
  • A.) Make sure the water supply is clean. Debris can cause excess pump wear and reduce performance. The maximum inlet water temperature is 140F (60C).
  • B.) An insufficient water supply will damage your pump. Make sure the water supply is steady and is 20% over the rated flow of your pump. Use a stopwatch to time how long it takes to fill a 5 gallon bucket with your garden hose.
    Example:
    If the rated flow is = 3gpm
    Then required flow = 3 x 1.20 = 3.6gpm
    5gallons / 3.6gpm = 1.39 minutes
    1.39min x 60sec/min = 83 seconds
    Therefore, you must be able to fill a
    5 gallon bucket in 83 seconds or faster.
  • C.) The water supply garden hose must have an inside diameter of at least 5/8″. If the hose is more than 100 ft. long, the diameter must be at least 3/4″.
  • D.) Never use a reservoir tank as a water source. This pressure washer is designed for a pressurized water source such as a city water faucet. Sucking water out of a tank may cause pump cavitation and damage to your pump. However, the inlet pressure of the pump must not exceed 115 psi (8 bar)
  • E.) Always use a flexible rubber hose for your water supply. Do not use rigid piping.
  • F.) Do not pump flammable liquids or liquids containing incompatible chemicals or solvents.
III.) Before Starting

WARNING: Check hoses, fittings, wand, gun and cords daily for signs of wear, cracks and looseness, and replace as required.

  1. Connect water supply hose to the garden hose connector located on the side of the unit.
  2. Connect high-pressure hose to quick connect outlet on front of the machine.
  3. Connect spray gun to high-pressure hose.
  4. If detergents will be used, only use detergents intended for pressure washers. Follow instructions on the detergent container.
IV.) To Start

DANGER: Do not point the spray wand at yourself or at any person. Bodily injury may result from water under high pressure.
Warning: Wear eye, ear, hand, foot and skin protection at all times while operating this pressure washer.
IMPORTANT: The water must be turned on before starting. Running the pump dry will cause damage and void warranty.

  1. Turn water supply ON.
  2. Squeeze the trigger to allow air to purge from the system. (this step goes faster with the pressure nozzle removed)
V.) Attach Nozzle

NORTHSTAR M157304S Cold Water Pressure Washer Owner’s Manual - Attach Nozzle

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.

NORTHSTAR M157304S Cold Water Pressure Washer Owner’s Manual - Attach NozzleWARNING: 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.

WARNING: Do not alter the unloader valve’s maximum pressure. Excess pressures could cause serious injury and/or pump damage. Any alteration other than turning the adjustment knob will void your warranty.

To Stop

  1. If detergents were used, draw clean water through the detergent inlet line to purge detergent. Failure to do so may clog the chemical injector.
  2. Turn the pump switch OFF.
  3. Turn OFF the water supply.
  4. Squeeze the trigger to relieve the system pressure.
