SPRAY NOZZLE SELECTION
Following is information concerning the four nozzles pro- vided with your pressure washer.
NOTE: The force of the spray on the surface you are cleaning increases as you move closer to the surface.
0° High Pressure (Red): The water stream discharged is very aggressive. Use with extreme caution to prevent damage to the surface being cleaned or injury to persons or animals.
15° High Pressure (Yellow): This is the nozzle used for most cleaning applications. It provides wide coverage and a powerful water stream.
40° High Pressure (White): This nozzle is used for cleaning with a wider coverage over a larger area with a powerful water stream.
65° Low Pressure (Black): Provides low pressure spray and a wide coverage. Used primarily when operating the chemical injector to apply chemicals.
Replacing the Nozzles
To replace a nozzle with a different nozzle, an easy quick connect has been added to the end of the wand. With the handle in the locked close position and the wand pointing away from the user. Pull back on the quick connect fitting and pull out the nozzle and replace with desired nozzle.
PUMP PREPARATION
The pump is shipped with a shipping plug, this will need to be replaced with the vent plug that is supplied.
PRESSURE ADJUSTMENT
PRESSURE ADJUSTMENT
The pressure is adjustable by turning the pressure adjust- ment knob located on the pump of the pressure washer. The knob must be set at the extreme clockwise position for maxi- mum pressure and turned several turns counter clockwise for maximum pressure.
NOTE: With the pressure adjustment knob turned to the maximum pressure position (clockwise), the pump pressure may exceed the rated pressure of the machine which could over load the engine. Adjust the knob counter clockwise to reduce the pressure and lower the power requirements of your pressure washer pump.
The pressure may also be regulated by the use of the engine speed.
