G0555X 14" Extreme Series Bandsaw
-19-
A properly tensioned blade is essential for mak-
ing accurate cuts and is a prerequisite for making
many bandsaw adjustments.
To tension the bandsaw blade:
1. Make sure that you have performed the Test
Run instructions on the previous page and
that the blade is tracking properly.
2. With the blade tension lever in the down
(engaged) position, adjust the blade ten
-
sion so the mark on the blade tension scale
matches the size of blade that is installed on
the bandsaw.
Note: Because each blade is different and all
blades stretch, this scale can only be consid
-
ered as a general guide.
3. Turn the bandsaw ON.
4. Release the tension one quarter of a turn at a
time. Do this very slowly. When you see the
bandsaw blade start to flutter, stop decreas
-
ing the tension.
5. Now, slowly increase the tension until the
blade stops fluttering, then tighten the tension
one more quarter of a turn.
6. Look at what the tension gauge reads and
use that as a guide for tensioning that blade
in the future.
Note: However, do not rely on this measure-
ment for long periods of time because the
blade will stretch with use.
NOTICE
To reduce blade stretching, remove the ten-
sion from the blade when not in use.
NOTICE
After blade tension and tracking are set cor-
rectly, properly adjust the upper/lower sup
-
port bearings and guide-block assemblies
into position before cutting operations.
The support bearings are positioned behind the
blade and support the back of the blade dur
-
ing cutting operations. Proper adjustment of the
support bearings is an important part of making
accurate cuts and also keeps the blade teeth from
coming in contact with the guide bearings while
cutting.
To adjust the support bearings:
1. Make sure that the blade is tracking properly
and that it is correctly tensioned.
2. DISCONNECT BANDSAW FROM POWER!
3. Familiarize yourself with the support bearing
controls shown in
Figure 18.
4. Loosen the lock bolt shown in Figure 18.
