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.

4.Check chain lubrication. Refer to the Maintenance Section for further details.

The Model G1033Õs 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.
