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.
(The
L
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)
䡬 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
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.
Fig. 7
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.
䡬 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 61-70 In-lbs. (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)

䡬 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)
Fig. 9
䡬 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)
