Chain Adjustment
SECTION 5: ADJUSTMENTS
The chain drive in the Model G1033 transfers
movement from the hand wheel driven column to
the three other support columns. The chain drive
may require adjustment to remove slack as the
chain stretches over time, or as part of table lev-
eling procedures. To adjust the chain:
1. Remove the two access panels on the
stand.
2. Loosen the two locking bolts and move the
idler sprocket until chain play has been
eliminated. See Figure 7.
3. Re-tighten the two locking bolts.
4. Check chain lubrication. Refer to the
Maintenance Section for further details.

Table Adjustment
The Model G1033’s table movement is critical to
the operation of the machine. As such, it is
essential that the table is aligned correctly with
the cutterhead and the head casting. For the
power feed to work correctly, it is important that
the table be the same distance from the head
casting in front and back. To make table adjust-
ments, it will be necessary to construct the mea-
surement block ''A''. See page 36 for a full size
print of block ''A''. To adjust the front-to-back dis-
tances:
1. Place Block ''A'' on the front right corner of
the table and raise the table until the top of
the block comes in contact with the bottom
of the head casting.
2. Without moving the table position, move
the block to the rear right corner under the
head casting. If the block will not fit under
the head casting, or if the gap between the
head casting and the table exceeds .016''
(use a feeler gauge to determine gap) you
will need to adjust the chain drive. See
Figure 8.
