4. Drain the water from the washer (Fig. 23)
(1) Tilt the washer to drain out the residual water.
(2) Wipe away all moisture with a dry cloth.
CAUTION
Water left in the washer may freeze in the winter, which
could result in damage to the pump.

SAFETY MECHANISMS

The washer is equipped with the following safety mechanisms
to ensure safe usage.
Power switch
This prevents the washer from being unintentionally
operated.
Trigger gun equipped with a lock
This prevents the trigger from being pulled, unintentionally
operating the washer.
Pressure switch
This prevents the pressure inside the washer from
exceeding permissible levels. Releasing the lever on the
trigger gun causes the valve operated by water pressure
to halt pump operations, which allows the pressure to be
released through the water feed. The pump is started
again when the lever is pulled.
Thermal protector
This protects the motor by halting operations when
abnormal heat is detected in the motor. It will start
operating again when the motor cools down.
