Personal Protective Gear
WARNING: High pressure spray hazard
High-pressure spray can injure eyes/skin. Hot water can
burn. Flying objects and debris can cause injury.
Serious injection injury can result if high-pressure spray
penetrates the skin.
When operating the machine, wear:
• Waterproof, thermally insulated gloves
• Safety glasses with side and top protection
• Protective clothing
• Non-slip, protective footwear
• Respirator or mask to avoid inhalation of vapors if
directed on the chemical label (if spraying
chemicals).
Purging
Note: Pressure washer will first be purged using
water supply pressure only, not pressure washer
pump. Do not plug electric pump in yet.
• Turn on water supply.
• Disengage safety latch and squeeze trigger to attain
a steady stream of water. This purges the pump of air
and impurities.
• To prevent accidental spraying, engage the safety
latch on spray gun trigger by rotating it to the locked
position.
Figure 11
Step 3. Spraying
• Make sure you have attached the appropriate spray
nozzle.
• Clear the cleaning area of all persons. Keep children
and pets away.
Starting
• Plug unit into a grounded outlet. Press RESET on the
GFCI (if applicable).
• Start motor to power the pump by turning Power
Switch ON.
Spraying Procedure
• Never run the machine without sufficient pump oil or
sufficient water to cool the pump.
• Hold the spray gun firmly with two hands and a sturdy
stance (gun kicks back when triggered).
• Nozzle should be 12” to 24” from the work, closer for
tough areas.
• Disengage safety latch and start spraying at the top
using long, even, side-to-side, overlapping passes.
• The pressure washer is set and locked to the
maximum rated pressure when it leaves the factory.
To reduce the pressure, turn the Unloader knob
counterclockwise (Figure 12).
Figure 12
• If temporarily stopping, interrupting spray, rotate
trigger safety latch downward to the locked position to
guard against accidental trigger release.
Note: Do not attempt to secure the spray gun open by
blocking or tying the spray gun in the on position.
Uncontrollable hose whipping can occur if grip is lost.
• Always turn off the motor by turning Power switch off
and then activate spray gun trigger to relieve system
pressure when:
• The sprayer is unattended, or when
• Disconnecting hoses, installing/cleaning nozzles,
or servicing the pump.
Using Chemicals for Cleaning (if desired)
Use only NorthStar pressure washer chemicals or
chemicals specifically formulated for use with pressure
washers. Don’t use acids, corrosives, or abrasive or
flammable liquids. Breathing hazards, surface
burns/corrosion, or fire/explosion could result.
Follow the Chemical Manufacturer’s Label Instructions
When Handling or Spraying Chemicals:
• Understand all safety hazards and first aid for all
chemicals being used.
• Wear protective gear as directed. Always wear
protective gloves when handling and cleaning
with chemicals.
• When cleaning filters, check whether dangerous
chemicals have been used with the filter and take
any precautions that may have been
recommended by the supplier of these chemicals.
• Always dispose of hazardous fluids per local,
state, and national guidelines.
