NOTICE
Whenever changing a blade or adjusting tension
and tracking, the upper and lower support bearings
and guide blocks must be properly adjusted before
operation.
The support bearings are positioned behind the blade for
support during cutting operations. Proper adjustment of
the support bearings is an important part of making accu-
rate cuts and also keeps the blade teeth from coming in
contact with the guide blocks while cutting.
To adjust the upper support bearing, do these steps:
1.
DISCONNECT BANDSAW FROM POWER!
2.
Make sure the blade is tracking properly and that it
is correctly tensioned.
3.
Familiarize yourself with the upper support bearing
controls shown in
Figur
e 32
.
4.
Loosen the set screw on the support bearing shaft
(
Figur
e 32
)
.
5.
Place a 0.016" feeler gauge between the support
bearing and the blade, and position the bearing
0.016" away from the back of the blade as illustrated
in
Figure
33
.
Note:
For a quick gauge, fold a dollar bill in half
twice (four thicknesses of a dollar bill is approxi-
mately 0.016") and place it between the support
bearing and the blade.
6.
Tighten the set screw to keep the support bearing
locked in place.
To adjust the lower support bearing, do these steps:
1.
Repeat
Steps 1-3
.
2.
Loosen the lower support bearing shaft set screw
(
Figure 34
).
3.
Place a 0.016" feeler gauge between the support
bearing and the blade, position the bearing 0.016"
away from the back of the blade (
Figure 33
), and
tighten the set screw.
