Prior To Operation; How To Use - Hitachi WH 18DDL Bedienungsanleitung

CAUTION
When the battery charger has been continuosly used, the battery charger
will be heated, thus constituting the cause of the failures. Once the charging
has been completed, give 15 minutes rest until the next charging.
If the battery is recharged when it is warm due to battery use or exposure to
sunlight, the pilot lamp map light in green.
The battery will not be recharged. In such a case, let the battery cool before
charging.
When the pilot lamp flickers in red (at 0.2-second intervals), check for and
take out any foreign objects in the charger's battery installation hole. If there
are no foreign objects, it is probable that the battery or charger is
malfunctioning. Take it to your authorized Service Center.

PRIOR TO OPERATION

1. Preparing and checking the work environment
Make sure that the work site meets all the conditions laid forth in the
precautions.
2. Checking the battery
Make sure that the battery is installed firmly. If it is at all loose it could come
off and cause an accident.
3. Installing the bit
Always follow the following procedure to install driver bit. (Fig. 5)
(1) Pull the guide sleeve away from front of the tool.
(2) Insert the bit into the hexagonal hole in the anvil.
(3) Release the guide sleeve and it returns to its original position.
(4) If you want to remove the bit, pull the guide sleeve away from front of the
tool.
CAUTION
If the guide sleeve does not return to its original position, then the bit is not
installed properly.

HOW TO USE

1. Check the rotational direction
The bit rotates clockwise (viewed from the rear side) by pushing the R-side
of the push button.
The L-side of the push button is pushed to turn the bit counterclockwise.
(See Fig. 6) (The L and R
2. Switch operation
When the trigger switch is depressed, the tool rotates. When the trigger is
released, the tool stops.
The rotational speed of the drill can be controlled by varying the amount
that the trigger switch is pulled. Speed is low when the trigger switch is
pulled slightly and increases as the trigger switch is pulled more.
NOTE
A buzzing noise is produced when the motor is about to rotate. This is only
a noise, not a machine failure.
3. Using the hook
The hook is used to hang up the power tool to your waist belt while working.
CAUTION
When using the hook, hang up the power tool firmly not to drop accidentally.
If the power tool is dropped, it may lead to an accident.
When carrying the power tool with hooked to your waist belt, do not fit any
bit to the tip of power tool. If the sharp bit such as drill is fitted to the power
tool when carrying it with hooked to your waist belt, you will be injured.
Install securely the hook. Unless the hook is securely installed, it may cause
an injury while using.
(1) Removing the hook.
Remove the screws fixing the hook with Philips screw driver. (Fig. 7)
(2) Replacing the hook and tightening the screws.
Install securely the hook in the groove of power tool and tighten the
screws to fix the hook firmly. (Fig. 8)

The battery remaining power is enough.
The battery remaining power is a half.
The battery remaining power is nearly
empty. Re-charge the battery soonest possible.
As the remaining battery indicator shows somewhat differently depending
on ambient temperature and battery characteristics, read it as a reference.
NOTE
Do not give a strong shock to the switch panel or break it. It may lead to a
trouble.
