recommendations:
• Reduce the recommended band tension when using
saw bands with a coarser pitch or lighter gage.
• Increase the recommended band tension when
using heavier gage saw bands.
Saw Band Tracking
1. The upper and idler bandwheels can be tilted a
maximum of three (3) inches (76.2 mm) forward and
backward to help obtain correct saw band tracking.
A saw band is tracking properly when the saw band's
back edge is against the bandwheel ange and just
touching the saw guide back-up bearings.
It is recommended that proper band tracking
over the upper and lower bandwheels be
attainedrstBEFOREtrackingthesawband
over three (3) bandwheels.
2. The following tracking procedures are to be
performed with the band drive motor off and the
transmission in "neutral": (a) Open all bandwheel
doors; (b) Manually turn the bandwheels to observe
how the saw band is tracking.
Tilt Adjustment Handles.
3. To adjust bandwheel tilt if tracking is not correct:
(a) Loosen the tilt lock handle; (b) Turn the tilt
adjustment handle until the saw band tracks
