Shutdown - North Star 990990 Owner's Manual

Procedure:
1. Install the high-pressure spray nozzle (always relieve
system pressure first and follow instructions for
attaching a nozzle).
This pressure washer is equipped with an On-Demand
feature. This feature will shut-off the motor when the
operator is not spraying and may appear as if the pressure
washer is off if left unattended. Always turn off the motor
and relieve system pressure when finished spraying or
when leaving sprayer unattended. Serious injury could
result from unintentional release of high-pressure spray.
2. Clear the cleaning area of all persons. Keep children
and pets away.
3. Hold the spray gun firmly with two hands and a sturdy
stance -- Gun kicks back when triggered.
4. 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.
5. Use the width of the spray pattern to wash a wide
path. Overlap spray paths for complete coverage.
6. The nozzle should be 12" to 24" from the work, closer
for tough areas.
7. Small parts should be washed in a basket, so the
pressure does not push them away. Larger,
lightweight parts should be clamped down.
8. 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. To return to maximum pressure turn
knob clockwise.
Unloader
9. If temporarily interrupting spraying, rotate trigger
safety latch downward to the locked position to guard
against accidental trigger release
WARNING

Operation
Do not attempt to alter the unloader valve's maximum
pressure. Excess pressure could cause serious injury

Any alteration other than turning the adjustment knob will
void your warranty.
When not spraying, use the spray gun safety lock
to prevent accidental high-pressure discharge.
