Hitachi AW130 Handling Instructions Manual page 35

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. 18)
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. 19)
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.
