Prepare to wash small parts in a basket so the pressure

lightweight parts.
Personal Protective Gear
WARNING: High pressure spray hazard
•
High pressure spray can cause injection injury, eye injury, and
loss of balance. Serious injury could result from unintentional
release of high-pressure spray from the gun upon engaging the
trigger.
•
ALWAYS turn power switch to OFF position and relieve system
pressure when leaving pressure washer unattended.
•
Total Start/Stop feature allows temporary motor shut-off (STOP)
when the trigger is disengaged and allows motor turn-on
(START) when the trigger is reengaged. This feature should
NEVER be used to shut-off pressure washer when not in use.
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.

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 (Fig.1574210_9J).
•
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.
