5. Tighten lock nuts and recheck alignment.
Note: DO NOT over tighten lock nuts. Bearing
blocks will break if over tightened.
1. DISCONNECT MACHINE FROM POWER!
2. Starting with infeed (front) sanding drum,
lower table so gauge block slides easily
under pressure bars. Slide block over to right
side of table, with front edge lined up to front
of table.
Note: Make note of gauge block position to
make sure same part of the gauge block is
used to set drum heights.
3. Raise table up so gauge block just touches
infeed pressure roller, and then raise table
one full turn of crank handle.
4. Adjust height of right side of front sanding
drum so it just touches gauge block and is
able to rotate back and forth with moderate
resistance.
5. Mark location of crank handle with a felt
pen or piece of tape. In same manner, mark
height of table in relation to the body of sand-
er. Both these marks indicate exact table
position (referred to as Reference Height #1).
Note: Having Reference Height #1 marked is
crucial to all subsequent steps.
6. Lower table two full turns. Remove gauge
block and re-insert it on left side of table.
Take care to line it up with front of table just
as it was done on previous side.
7. Raise table two full turns to bring it back up to
Reference Height #1.
8. Set height of front sanding drum to gauge
block (refer to
Adjusting Drum Height on
This Page for instructions).
1. Loosen lock nuts (see Figure 84) on bearing
block on side of drum requiring adjustment.

9. Rotate front sanding drum back and forth.
It should feel and sound as it did in Step 4.
If not, adjust drum height again. Continue
this process, going back and forth, until both
sides of drum feel and sound the same.
10. Lower table (
1
⁄
8
) turn from Reference Height #1
and mark location of crank handle and table
in relation to the body of sander. Both these
marks indicate exact table position (referred
to as Reference Height #2).
Note: Model G1066Z has micro-adjustment
controls on sides of machine for rear sanding
drum adjustments. Other than this difference,
the procedure for setting rear drum height is
the same.
11. Lower table two full turns.
12. Using Reference Height #2, repeat Steps 7–9
on rear sanding drum until both sides of drum
feel and sound the same.
Note: Outfeed drum should always be slightly
lower than infeed drum, the actual difference
will vary depending on wood type, feed rate,
sandpaper grits, etc. Once familiar with the
adjustment process, experiment to determine
the best settings for your specific application.
