PRIOR TO OPERATION

1.Installation of an earth leakage circuit breaker

It is recommended that an earth leakage circuit breaker is connected to the washer to shut o the power if leaking current exceeds 30 mA for 30 milliseconds in order to prevent electric shocks.

2.Keep the work area neat and tidy

Dirty water will be sprayed about when using the washer. It is therefore necessary to check the area to make sure there are no hindrances, and keep the work area neat and tidy.

3.Situating the washer

Select flat locations where the washer will not be splashed with water when cleaning.

4.Using extension cords

Make sure the cord is thick enough to provide a constant supply of electricity, and use cords that are as short as possible.

Acceptable cord thicknesses (Nominal cross sectional area cable) and cord length are indicated in the table below.

INSPECTIONS PRIOR TO USE

WARNING

Check the following before using the washer. Check the items listed in 1 and 2 before plugging into the power socket.

1. Check to make sure the switch is at the “OFF” position (Fig. 4)

Plugging the washer into the power socket with the switch set at “ON” will cause the washer to immediately begin operating, which may result in unexpected injuries.

2. Check the power supply Only use a rated voltage.

Do not use motor engines are direct current. Failure to observe this will not only result in damage to the washer, it is also very dangerous.

3. Check the power socket

If the power socket is loose or the plug is easily dislodged, it needs to be repaired.

It is dangerous to use it in this condition. Consult with your local electrical engineering outlet.

ATTACHING PARTS

Make sure all parts are correctly attached in the following sequence in order to guarantee safe usage.

WARNING

Switch o the washer and disconnect it from the power socket without fail to prevent unexpected accidents.

1. Attach the water feed connector to the water feed inlet on the washer (Fig. 5)

Remove the cap on the washer’s water feed inlet and firmly attach the water feed connector.

Loose connections may result in water leaks.

2. Attaching the high-pressure hose to the washer’s water outlet (Fig. 6)

Both ends of the high-pressure hose have the same configuration, so either end may be connected. Remove the water outlet cap from the washer, insert the high-pressure hose into the water outlet and then rotate the high-pressure hose ring to fix it in place.

NOTE

Moisten the O-ring with water if it is dicult to insert the hose.

If it is not possible to tighten the ring, it means that the high-pressure hose has not been inserted far enough.

3. Attach the high-pressure hose to the trigger gun. (Fig. 7)

Grip the thick end of the high-pressure hose, insert it into the connector on the trigger gun, and then rotate the ring on the hose to fix it in place.

NOTE

Moisten the O-ring with water to facilitate the connection if it is dicult to insert the hose.

If the ring cannot be tightened, it means that the end of the high-pressure hose has not been sucient inserted.

4. Attach the nozzle to the trigger gun. <Attachment (Fig. 8)>

(1) Align the protrusion on the nozzle with the entry hole on the trigger gun and press it into place.

NOTE

Remove all dirt, mud and other matter from the trigger gun’s entry hole and the protrusion on the nozzle. Moisten the O-ring with water to facilitate the connection if it is dicult to insert the nozzle.

(2) Press down firmly on the nozzle and then rotate it in the direction of the arrow until it stops (half rotation.)

(3) Check to make sure that the nozzle cannot be pulled out once it has been attached.

<Detachment (Fig. 9)>

Press down firmly on the nozzle and then rotate it counter- clockwise until it stops. The nozzle can be withdrawn at that position.

USING DIFFERENT NOZZLES

Variable nozzle (Fig. 10)

The variable nozzle can be used to alternation between “Jet” and “Spray”.

Rotate the end on the nozzle clockwise for “Jet”, and counter-clockwise for “Spray”.

• Jet washer

A water jet is discharged in a direct line to remove stubborn mud and other dirt from agricultural machinery, etc.
