Attach the head assembly of the drill to the top of the column and secure
using both the M10 x 12 mm blind set screws which are pre-installed to the
collar of the head assembly
(Fig. 7.5)
. Before placing the head assembly
onto the column, ensure that the blind set screws do not protrude into the
inside of the head assembly. Before fully tightening the screws check that
the head is correctly aligned with the base so that the spindle is above the
centre line of the base casting.
To attach the feed handle to the head assembly, align the roll pin on the
inside of the handle collar
(Fig. 7.6)
with the slot in the rise and fall pinion
shaft
(Fig. 7.7)
and secure in place using the M8 x 25 mm socket head cap
screw
(Fig. 7.8)
