Bearings
The blade guides provide side-to-side support to keep
the blade straight while cutting. The blade guides are
designed to be adjusted in two ways—forward/backward
and side-to-side.
To adjust the upper blade guides, do these steps:
1. Make sure the blade is tracking properly and that it
is correctly tensioned.
2. DISCONNECT BANDSAW FROM POWER!
3. Familiarize yourself with the upper blade guide con-
trols shown in Figure 27 & 28.
4. Loosen the lateral adjustment rod bolt, loosen the
support bearing adjustment shaft bolt, and adjust
the blade guides until the edges of the bearings are
1 /
16
" behind the blade gullets, as illustrated in Figure
29.
Note:.The 1 ⁄
16
" spacing is ideal, although with larger
blades it may not be possible. In such cases, adjust
the guide bearings as far forward to the blade gul-
lets as possible, and still maintain the proper sup-
port bearing spacing adjustment.
