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 finger in the center of the trigger during operations (Fig. 20)

Failure to observe this may result in injury from pinched fingers.

Grip the gun and nozzle firmly 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 insucient 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 eectively 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 flow 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 o, 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 o. Failure to observe this may result in malfunctions.

2. Set the switch to the “ON” position (Fig. 21)

The motor will start operating when the washer is switched on. The motor will automatically switch o once sucient water pressure has built up inside the washer.

3. Pull the trigger (Fig. 22)

Hold the trigger gun firmly 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. 23)

The trigger gun is fitted 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.
