Before Use; Operation - Hitachi DV 18DBFL Safety Instructions And Instruction Manual

CAUTION:
● When the battery charger has been continuously
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 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 pilot lamp of the charger lights for
1 second, does not light for 0.5 seconds (off for
0.5 seconds). In such a case, first let the battery
cool, then start charging.
● When the pilot lamp flickers rapidly 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.

BEFORE USE

Check the work area to make sure that it is clear of debris
and clutter.
Clear the area of unnecessary personnel. Ensure that
lighting and ventilation is adequate.

OPERATION

1. Mounting and dismounting of the bit.
(1) Mounting the bit.
Loosen the sleeve by turning it toward the left (in
the counterclockwise direction as viewed from the
front) to open the clip on the keyless chuck. After
inserting a driver bit, etc., into the keyless drill
chuck, and tighten the sleeve by turning it toward
the right (in the clockwise direction as viewed from
the front). (See Fig. 5).
Loosen
Tighten
NOTE:
If the sleeve becomes loose during operation,
tighten it further.
The tightening force becomes stronger when the
sleeve is tightened.

(2) Dismounting the bit
Loosen the sleeve by turning it toward the left (in
the counterclockwise direction as viewed from the
front), and then take out the bit etc. (See Fig. 5)
NOTE:
If the sleeve is tightened in a state where the clip
of the keyless chuck is opened to a maximum limit,
a click noise may occur. This is the noise that occurs
when the loosening of the keyless chuck is
prevented and is not a malfunction.
When it is no longer possible to loosen the sleeve,
use a vise or similar instrument to secure the bit.
Set the clutch mode between 1 and 11 and then
turn the sleeve to the loose side (left side) while
operating the clutch. It should be easy now to
loosen the sleeve.
2. Confirm that the battery is mounted correctly.
3. Check the rotational direction.
The bit rotates clockwise (viewed from the rear
side) by pushing the R-side of the selector button.
The L-side of the selector button is pushed to turn
the bit counterclockwise (See Fig. 6).
(The and marks are provided on the body.)

Trigger switch
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.
When releasing the trigger of the switch, the brake
will be applied for immediate stopping.
