Hitachi AW100 [15/124] English

English

• Jet washer

A water jet is discharged in a direct line to remove

stubborn mud and other dirt from agricultural machinery,

etc.

• Spray washer

The water is discharged in a wide fan for cleaning walls,

motorbikes and automobiles, etc.

The entire nozzle can be rotated by approximately 90

degrees to change the shape of the spray between

horizontal and vertical.

NOTE

○ Set the spray adjustment to “Jet” ﬁ rst of all, and then

gradually move it to the “Spray” position while pulling the

trigger.

Note that there is a chance of the water being sprayed

horizontally over a wide area if this is rotated fully to the

“Spray” position.

○ Note that the nozzle may be damaged if it is forced to

move past the stop position when alternating between

“Jet” and “Spray”.

Detergent bottle nozzle (Fig. 11 and 12)

Sprays water mixed with detergent.

Uses neutral detergents available on the open market.

(1) Insert the water feed pipe into the detergent nozzle.

(2) Pour an undiluted neutral detergent into the bottle and

then screw the bottle onto the detergent nozzle.

(3) Attaching and removing the detergent bottle nozzle is the

same as explained for other nozzles.

When inserting the detergent bottle, make sure that

the trigger gun is pointing in the direction shown in the

illustration on the right.

(4) Aim the detergent nozzle at the article to be washed and

pull the trigger on the trigger gun to spray a mixture of

water and detergent at low pressure.

WARNING

Do not use acidic or alkali detergents. Use only neutral

detergents available on the open market.

Using detergents other than neutral detergents or

chemical agents may result in accidents or malfunctions.

NOTE

Moisten the O-ring with water if it is diﬃ cult to insert the

nozzle.

WASHING

WARNING

○ Do not switch the washer on while the trigger is being

pulled.

Failure to observe this may result in high-pressure water

being sprayed immediately, leading to unexpected

accidents.

○ Do not point the nozzle at people or animals.

Failure to observe this may result in injury.

CAUTION

○ Set the switch to “OFF” immediately if the hose becomes

detached from the faucet or washer, and if water is no

longer being fed to the washer.

Failure to observe this may result in immediate

malfunctions (dry operations.)

○ Set the switch to “OFF” without fail when temporarily

suspending operations.

Failure to observe this may result in the motor

automatically starting up.

○ Place your ﬁ nger in the center of the trigger during

operations (Fig. 13)

Failure to observe this may result in injury from pinched

ﬁ ngers.

Grip the gun and nozzle ﬁ rmly with both hands.

○ The trigger gun may kick back when water is discharged.

NOTE

○ Do not use the water hose when it is wound onto the reel.

Failure to observe this may result in insuﬃ cient water

feed.

○ Commence initial washing approximately 2 to 3 meters

away from the targeted item, and then move gradually

closer while checking the level of cleaning until you reach

a distance in which soiling is eﬀ ectively washed away.

The pressure of the spray from the washer is

approximately 20-times greater than tap water. High-

pressure water jets may therefore damage or peel the

coating from the items being washed.

○ There are cases when the water spray will appear

unstable owing to the fact that air that has built up in

the pump and hose is purged together with the water

immediately after use. In this event, allow the water to

ﬂ ow out until it stabilizes.

○ Leave two or more seconds gap between pulling and

releasing the trigger.

Failure to observe this may result in the pressure switch

malfunctions.

○ Do not use the washer for more than thirty consecutive

minutes without giving it a break.

1. Open the faucet to its fullest.

Point the nozzle in a safe direction and then fully open the

faucet. Check to make sure no water is leaking from the

joints.

Release the trigger stopper with the washer switched oﬀ ,

pull the trigger on the trigger gun to discharge a small

amount of water from the nozzle with just the pressure

from the tap water. Check to make sure that no water is

leaking.

NOTE

Do not switch the washer on with the faucet turned oﬀ .

Failure to observe this may result in malfunctions.

2. Set the switch to the “ON” position (Fig. 14)

The motor will start operating when the washer is

switched on. The motor will automatically switch oﬀ once

suﬃ cient water pressure has built up inside the washer.

3. Pull the trigger (Fig. 15)

Hold the trigger gun ﬁ rmly in both hands, point the nozzle

at the item to be washed, and then pull the trigger.

The high-pressure water jet will spray out.

Adjust the nozzle between “Jet” and “Spray” in

accordance with need.

Trigger stopper (Fig.

16)

The trigger gun is ﬁ tted with a trigger stopper to prevent

the trigger from being pulled.

The trigger is locked and released by pressing the

stopper in the direction shown by the arrows.

NOTE

Lock the trigger with the trigger stopper during pauses

and after washing has been completed.

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.
