ADJUSTING THE SPRAY
The nozzle is adjustable to allow you to adjust the spray from a narrow jet of
water to a wide spray.
To adjust the nozzle, proceed as follows.
1. Hold the shaft of the lance in one hand.
2. Twist the nozzle with the other hand.
3. To vary the spray between narrow and wide, turn the nozzle counter-
clockwise through a half-of-a-turn. The narrow jet should be used to clean
small areas where a small spray is required. The wide beam should be used
for cleaning large areas.
ADJUSTING THE PRESSURE
The pressure setting is preset at the factory. To lower the pressure:
1. Adjust the pressure regulator on
the pump. Turn the pressure
regulator knob counter clockwise
to lower pressure. Once you have
finished using your power washer,
return the pressure regulator to its
original position.
2. Back away from the surface to be
cleaned. The further away you
are the less the pressure will be on
the surface being cleaned.
3. Reduce the speed of the engine (RPM). Slow the engine down and the
water pressure will also go down.
4. Adjust the spray to a wider angle.
5. Slide the nozzle forward for low pressure and backwards for high pressure.
