7-5. Attaching Angle Attachment Ass’y
(1) Removing the drill chuck from drill (Refer to section 8-1-2.)
(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 6.86--- 7.84 N
•
m (extent of force which
can be subjected by only a wrist with the open end
wrench provided to tighten 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.
Refer to section 8-1-4 for removal of the drill chuck from
the angle unit.
