4. ASSEMBLY
４-１７. Work clamp arm mechanism (KE-433B)
Install parts 1 to 6, clamp them using
parts 7 and 8 so there is no play in them,
and tighten the set screw 9.
Note:
Install so that the two ball bearings of
the feed bracket guide shaft assembly
do not fit into the holes in the feed
bracket guide plate.
Be careful not to drop these three
ball bearings when installing the
work clamp arm assembly.
Secure the work clamp
arm support shaft with the
set screw so that the
bottom of the work clamp
arm support plate and the
ball bearings touch when
the work clamp is raised.

assembly and feed plate.
