UPPER BLADE GUIDES AND BLADE SUPPORT BEARING (Fig. K, L)

WARNING

The blade guard has been removed for clarity of illustration. To avoid injury never operate the band saw without all guards in place and in working order.

To avoid injury, turn the switch OFF and disconnect the saw from the power source before making any

adjustments. NEVER make adjustments with the machine running.

NOTE: Make sure the blade is tensioned and tracking properly. Adjust the blade guides and support bearing after each blade tension and tracking adjustment. When the upper blade guides and support bearings are adjusted, the lower guides and bearings should also be adjusted.
