3. Extension cord
When the work area is removed from the power
source. Use an extension cord of sufficient thickness
and rated capacity. The extension cord should be
kept as short as practicable.
4. Selecting the appropriate drill bit:
When boring metal or plastic
Use ordinary metalworking drill bits.
When boring wood
Use ordinary woodworking drill bits.
However, when drilling 6.5 mm or smaller holes,
use a metalworking drill bit.
5. Mounting and dismounting of the bit
For keyed chuck (Fig. 1)
(1) Open the chuck jaws, and insert the bit into the
chuck.
(2) Place the chuck wrench in each of the three holes
in the chuck, and turn it in the clockwise direction
(viewed from the front side). Tighten securely.
(3) To remove the bit, place the chuck wrench into one
of the holes in the chuck and turn it in the
counterclockwise direction.
For keyless chuck
(1) Open the chuck jaws, and insert the bit into the
chuck.
To open the chuck jaws, hold the ring while turning
the sleeve in the counterclockwise direction (viewed
from the front side).
(2) Firmly grasp the ring and turn the sleeve in the
clockwise direction. Tighten securely.
(3) To remove the bit, firmly grasp the ring and turn
the sleeve in the counterclockwise direction.
(4) If it is hard to loosen the sleeve, fix the spindle
using the open-end wrench, hold the sleeve firmly,
and turn it in
(counterclockwise when viewed from the front). (Fig.
3)
6. Installing the side handle
For D10VG and D13VF
A Side handle is supplied with drill.
It can be installed on either side of the tool for right
or left handed use.
To install the side handle, thread it into the socket
on the desired side of the tool and tighten it securely.
(Fig. 4)
For D13VG
The large torque of the motor for this drill can result
in considerable reaction to your arms during drilling
work. Accordingly, make absolutely sure before use
that the side handle and the handle joint are
completely installed. (Fig. 5)
7. Check the rotational direction (Fig. 6)
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.
L
(The and R marks are provided on the body.)
8. Attaching the angle unit. (Optional accessory for
D13VF and D13VG)
(1) Removing chuck from drill (Fig. 7)
To remove the chuck from the drill, open the chuck
jaws as far as possible and turn out the locking
screw (left hand thread). This screw locks the chuck
7
(Fig. 2)
the loosening direction
to the spindle. And hold the drill so that only the
chuck rests firmly and squarely on the edge of a
solid bench. Install the hex. bar wrench into the
chuck. Turn the chuck until the wrench is at about
a 30° angle to the bench top and strike the wrench
sharply with a hammer so the chuck turns in the
counterclockwise direction (viewed from the front
side). This should loosen the chuck from the spindle
which has a right hand thread and you will be able
to remove the chuck by hand.
CAUTION:
If the chuck cannot be removed by striking the
wrench, don't strike the wrench forcibly and send
the drill to a HITACHI AUTHORIZED SERVICE
CENTER.
(2) Attaching the angle unit.
After removing the chuck, engage the coupling to
the drill spindle. Fit the joint sleeve to the gear
cover, attach the angle unit to the other end of the
joint sleeve, and turn the angle unit slightly in either
direction so the hex. hole in the coupling engages
the hex. portion of the angle unit spindle. Adjust
the direction of the angle unit and tighten the joint
sleeve by clamping bolts.
Tighten two clamping bolts equally and gradually
in turn with a torque of 70–80kg-cm. (extent of force
which can be subjected by only a wrist with the
open end wrench provided to tight clamping bolts.).
(Fig. 8)
To operate the angle unit at low speed, attach the
chuck to the angle unit spindle at the side marked
"LOW" and secure the locking screw. At this setting,
the drilling speed is decreased to about 70% and
the drilling torque increased to about 150%. (Fig.
9)
To operate the angle unit at high speed, attach the
chuck to the angle unit spindle at the side marked
"HIGH" and secure the locking screw. At this setting,
the drilling speed is increased to about 150% and
the drilling torque decreased to about 70%. (Fig. 10)
(3) Installing the side handle (Fig. 11)
The side handle can be installed on either side of
the angle unit for right or left handed use. To install
the side handle, thread it into the socket on the
desired side of the angle unit and tighten it securely.
(4) Removing chuck from angle unit (Fig. 12)
The chuck can be removed from angle unit in the
same manner it was removed from the drill;
however, ALWAYS REMOVE ANGLE UNIT FROM
THE DRILL BEFORE ATTEMPTING TO LOOSEN
CHUCK. This will prevent damage of drills gear. Use
open end wrench provided to hold angle unit spindle
before attempting to loosen chuck.
CAUTION:
If the chuck cannot be removed by striking the
wrench, don't strike the wrench forcibly and send
the drill to a HITACHI AUTHORIZED SERVICE
CENTER.
9. Attaching the hook. (Optional accessory) (Fig. 13)
To attach the hook, it is necessary to disassemble
the handle portion which covered the tool's electrical
system. For your continued safety and electrical
shock protection, installing the hook on this drill
should ONLY be performed by a HITACHI
AUTHORIZED SERVICE CENTER.
