ADJUSTABLE SPRAY NOZZLE
Water may be sprayed out from the spray nozzle either linearly or in fan shapes. Turn on the pressure
washer first and then adjust the nozzle by turning the end of the nozzle in a clockwise or anti clockwise
direction.
MAINTENANCE
The Osaki Pressure Washer is maintenance-free however regular inspection of the water inlet filter on the
side will prevent any blockage restricting the water supply to the pump.
LONG TERM STORAGE
Frost can destroy an incompletely emptied unit. The pressure washer must be stored in a frost-free
environment.
After long term storage without operation, it is possible that scales have formed inside the machine, making it
difficult to start. In such conditions it is recommended to turn off and disconnect the power supply and rotate
the motor by hand. This is achieved by putting a screwdriver through the ventilation grill and turning the motor
several times. This will help to avoid excessive current draw on the motor and the power supply.
