G1066/G1066Z/G1079 Drum Sander

5.Stop and mark the location of the table ele- vation handle with a felt pen or piece of tape. In the same manner, mark the height of the table in relation to the body of the sander. Both of these marks will indicate this exact table position (we will refer to it as reference height #1). Having reference height #1 marked is crucial to all subsequent steps.

6.Lower the table exactly 2 turns. Remove the block and re-insert it on the other side, taking care to line it up with the front of the table just as it was on the previous side. Raise the table exactly 2 turns to bring it back up to ref- erence height #1.

7.Set the height of that end of the drum to the board. Rock the drum back and forth again. It should feel and sound the same as it did on the other end. If the sound and rolling action are not identical, adjust the bearing block height. Continue this procedure, going back and forth, until both sides of the drum sound and feel the same.

8.To adjust the rear drum, lower the table by turning the handwheel counter-clockwise 1/8th of a turn from reference #1. Make a sec- ond mark. This will be reference #2 and will be used for setting up the rear drums.

9.Repeat steps 5-6until both sides of the rear drum are the same. (Note: the G1066Z has external height adjustment knobs for the rear drum. These are located on each side of the machine. Other than this difference, the pro- cedure for setting the drum height is the same.)

10.While the rear drum should always be slight- ly lower than the front drum, the actual differ- ence will vary depending on wood type, feed rate, sandpaper grits, etc. Once you are familiar and comfortable with the adjustment procedures, you should experiment to arrive at the best settings for your specific applica- tion.

In addition to premature wear and failure of sandpaper, improper drum alignment could cause the possibility of an uncontrolled exit of material from the machine—which could result in damage to property or potential operator injury.
