GUIDE ARM POSITIONING

The adjustable guide arm should always be adjusted with respect to the material width. It will optimize

cutting conditions and increase blade life with the guide arm adjusted as close to the material as permitted.

In order to adjust the guide arm, the remote guide arm adjustment switch, located on the control console is

used to hydraulically position the guide arm. Turn the switch clockwise to move the guide arm toward the stock.
Turn the switch counterclockwise to move the guide arm away from the stock.
