For the Model G1066R/G1066Z/G1079R Drum
Sander to function properly, the sanding drums
must be aligned in two directions: (1) perpendicu-
lar to feed direction (see
Figure 81) and (2) paral-
lel to the conveyor belt (see
Figure 82).

1. DISCONNECT MACHINE FROM POWER!
2. Measure distances between outside of infeed
(front) sanding drum and inside of front brace
on both ends of the drum.
— If distances are within
1
⁄
8
" of one another,
no adjustment is necessary.
— If distances are not within
1
⁄
8
" of one
another, infeed sanding drum needs to be
aligned. Proceed to
Step 3.
3. Repeat Step 2 on outfeed (rear) sanding
drum.
— If distances are within
1
⁄
8
" of one another,
no adjustment is necessary.
— If distances are not within
1
⁄
8
" of one
another, outfeed sanding drum needs to
be aligned. Proceed to
Step 4.
Note: If sanding drums are not perpendicular
to feed direction, sandpaper will creep toward
one end of drum during operation.
4. Loosen lock nuts on bearing blocks (see
Figure 83) and adjust sanding drum forward
or backward as necessary until distances
between outside of drum and inside of front
brace on both ends of drum are within
1
⁄
8
" of
one another.
Improper drum alignment could cause
an uncontrolled exit of material from the
machine—which could result in damage
to property, premature wear and failure of
sandpaper, or personal injury.
