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.
Blade guides (Fig. K)
1. Make sure the blade is tensioned and tracking properly.
2. Loosen the front hex socket screws (1) with a hex
wrench.
3. Move the guides (2) as close to the blade (3) as possible
without pinching it.
4. Using a feeler gauge, make sure the space between
each guide and blade measures 0.02" (the thickness of
a dollar bill).
5. Tighten the hex socket screws.
