Hitachi AW 100 Mode D'emploi page 15

• 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.
