ADJUSTING OVERARM COLUMN
If side motion develops in the overarm, after extended
use, it can be corrected as follows:
1. DISCONNECT MACHINE FROM
POWER SOURCE.
2. Loosen hex nuts (A) Fig. 36, and gib adjusting
screws (B) and (C).
3. Adjustment to the column base is made by loosening
hex nuts (D) Fig. 36, tightening or loosening bolts (E),
until column base wraps around column securely and
that the column can be raised or lowered without
binding. Tighten locknuts (D).
4. After column base is adjusted, tighten screws (C)
Fig. 36, against column gib until all side motion
disappears in overarm.

yoke (B) to desired position; to lock the yoke in position,
pull yoke clamp handle toward you.

yoke completely, or does not lock in a convenient
position, the handle can be adjusted as follows:
1. DISCONNECT MACHINE FROM

blade.
3. Remove rear end plate from track arm and remove
cuttinghead assembly (D) Fig. 37, from track arm.
