HOLDDOWN
The purpose of the holddown is to prevent the work-
piece from lifting as the chisel is raised up.
To adjust: Loosen set screw (A), position holddown (B)
until it just touches the top of the workpiece (C) and
allows the workpiece to slide left or right. Once hold-
down is in position, retighten set screw. SEE FIG. 26.
NOTE: The holddown can also be turned upside down
to accommodate thicker workpieces. When doing this,
tighten the set screw on the back side of the holddown.
SEE FIG. 26.

SLIDING FIT BETWEEN
HEAD AND COLUMN
A dovetail gib is provided on the rear of the head to
insure a good sliding fit between the head and the
column when the head is raised and lowered. This
should be set at the factory and should not need
adjustment. If adjustment is necessary, perform the
following steps.
A
1. Loosen two socket head cap screws (A) in the
dovetail gib (B) only slightly (less than 1/8 turn)
using provided hex wrench. SEE FIG. 28.

Fig. 28
2. Turn adjusting screws (C) clockwise to make a
tighter fit, turn counterclockwise for a looser fit.
NOTE: Correct adjustment is when a good snug sliding
fit is obtained without any side movement between the
gib and the column. This adjustment should not be too
tight that it restricts the sliding movement or too loose
that it affects accuracy.
3. Once proper fit is achieved, retighten the two
socket head cap screws.
