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.
Situating the washer
Select flat locations where the washer will not be splashed with water when cleaning.
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.
Failure to observe this may result in injury from pinched fingers.
Grip the gun and nozzle fi rmly with both hands.
This product contains a strong permanent magnet in the motor.
Observe the following precautions regarding adhering of chips to the tool and the eff ect of the permanent magnet on electronic devices.

NOTE

Loose connections may result in water leaks.
Moisten the O-ring with water to facilitate the connection if it is diffi cult to insert the hose and nozzle.
Remove all dirt, mud and other matter from the trigger gun’s entry hole and the protrusion on the nozzle.
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”.
Commence initial washing approximately 1 meter 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 7-times greater than tap water. Highpressure 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 turn the switch ON when the tank is empty or the faucet is shut off .

Hold the charger fi rmly and pull out the battery

NOTE
Be sure to pull out the battery from the charger after use, and then keep it.

Regarding electric discharge in case of new batteries, etc.
As the internal chemical substance of new batteries and batteries that have not been used for an extended period is not activated, the electric discharge might be low when using them the fi rst and second time. This is a temporary phenomenon, and normal time required for recharging will be restored by recharging the batteries 2 – 3 times.

How to make the batteries perform longer.

Recharge the batteries before they become completely exhausted.
When you feel that the power of the tool becomes weaker, stop using the tool and recharge its battery. If you continue to use the tool and exhaust the electric current, the battery may be damaged and its life will become shorter.
Avoid recharging at high temperatures.
A rechargeable battery will be hot immediately after use. If such a battery is recharged immediately after use, its internal chemical substance will deteriorate, and the battery life will be shortened. Leave the battery and recharge it after it has cooled for a while.

CAUTION

If the battery is charged while it is heated because it has been left for a long time in a location subject to direct sunlight or because the battery has just been used, the charge indicator lamp of the charger lights for 0.3 seconds, does not light for 0.3 seconds (off for 0.3 seconds). In such a case, fi rst let the battery cool, then start charging.
When the charge indicator lamp fl ickers (at 0.2-second intervals), check for and take out any foreign objects in the charger’s battery connector. If there are no foreign objects, it is probable that the battery or charger is malfunctioning. Take it to your authorized Service Center.
Since the built-in micro computer takes about 3 seconds to confi rm that the battery being charged with UC18YSL3 is taken out, wait for a minimum of 3 seconds before reinserting it to continue charging. If the battery is reinserted within 3 seconds, the battery may not be properly charged.
