To rem ove the chuck from the drill, open the
chuck jaw s 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 firm ly and
squarely on the edge of a solid bench. Install
the hex. bar w rench into the chuck. Turn the
chuck until the w rench is at about a 30° angle
to the bench top and strike the w rench sharply
w ith a ham m er so the chuck turns in the
counterclockw ise direction (view ed from the
front side). This should loosen the chuck
from the spindle w hich has a right hand
thread and you w ill be able to rem ove the
chuck by hand.
CAUTION:
If the chuck cannot be removed by striking
the w rench, don't strike the w rench forcibly
and send the drill to a HITACHI AUTHORIZED
SERVICE CENTER.
(2) Attaching the angle unit.
After rem oving 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 clam ping bolts.
Tighten tw o clam ping bolts equally and
gradually in turn w ith a torque of 61-70 In-
lbs. (70-80kg-cm ) (extent of force w hich can
be subjected by only a w rist w ith the open
end wrench provided to tight clamping bolts.).
