ON COMPLETION OF USE

Once the targeted item has been washed, drain the residual water from the washer and store it in a well-ventilated location to dry.

There are cases in which water left in the hose may freeze during the winter, so drain as much water as possible and store it indoors.

WARNING

Make sure all residual water is drained from the washer, the trigger gun and the hose, etc., after use.

Failure to observe this may result in freezing, leading to malfunctions.

1. Draining water from the washer (1) Stop the water supply.

(2) Set the switch to “ON” and pull the trigger on the trigger gun to drain the water from the inside of the washer. Continue this until water is no longer discharged (approximately 30 to 60 seconds.)

(3) Press the trigger stopper on the trigger gun to lock it in place.

2. Set the switch to “OFF”. (1) Switch o the washer.

(2) Unplug the power cord from the mains socket.

NOTE

Leaving the washer switched on may result in dry operations, leading to malfunctions.

3. Detach the trigger gun.

Follow the reverse procedure explained in “Attach the high-pressure hose to the trigger gun” to detach the trigger gun.

4. Rewind the high-pressure hose (Fig. 24)

Place the end of the high-pressure hose at a position lower than the reel and then rewind it while draining out all residual water.

5. Drain the water from the washer (Fig. 25) (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.

MAINTENANCE AND INSPECTION

WARNING

Switch o the washer and disconnect the plug from the power socket without fail when inspecting and cleaning it.

1. Inspecting the washer and hoses (Fig. 26)

Check to make sure that there is no damage, cracks or malformations.

Make sure you clean the hole on the nozzle with the nozzle cleaner pin supplied on a regular basis.

NOTE

Detach the trigger gun and clean the nozzle hole.

2. Inspecting the strainer (Fig. 27)

Wash all blockages out of the grid with water on a regular basis.

NOTE

Withdraw the strainer from the water feed inlet with the use of ﬂat radio pliers.

3. Clean the washer

Squeeze the excess moisture from a cloth soaked in soap and water and wipe the washer.

Do not use gasoline, thinner, benzene, kerosene, etc. Failure to observer this may result in malformations.

4. Check for loose screws.

Check for loose screws on a regular basis and tighten any screws that are loose. Failure to observe this could be dangerous.

5. Tidying up and storing the washer after use (Fig. 28)

The accessories can be stored inside the washer as shown in Fig. 28 when not in use and when being carried around.

Avoid the following environments and store the washer and accessories in a safe, dry location when not in use.

Do not store within the reach of children, or in locations where children can use it.

Do not store in location where rain can reach it, such as in front of the house, or in locations with high humidity.

Do not store in locations that are subject to drastic changes in temperature or direct sunlight.

Do not store in locations containing volatile substances that may ignite or explode.

6. Replacing supply cord

If the replacement of the supply cord is necessary, it has to be done by a Hitachi Authorized Service Center to avoid a safety hazard.
