Tensioning Blade

A properly tensioned blade is essential for making
accurate cuts and is a prerequisite before making
many bandsaw adjustments.
To tension the bandsaw blade:
1. Make sure you have performed the Test Run
instructions on Page 24 and that the blade is
tracking properly.
2. Raise the upper blade guide assembly as
high as it will go, and adjust the upper and
lower guide blocks as far away from the blade
as possible.
Note: This procedure will not work if the guide
blocks have any contact with the blade.
3. Adjust the blade tension knob until it matches
the blade size on the bandsaw.
Note: This scale can only be considered as
a general guide, follow these steps to accu-
rately set the blade tension.
4. Turn the bandsaw ON.
5.
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.
6.
Now, slowly increase the tension until the
blade stops fluttering, then tighten the tension
another quarter turn.
7.
Look at what the tension gauge reads and
use that as a guide for tensioning that blade
in the future.
Note: Detension blade after use to increase
blade life and reduce strain on machine.
After blade tension and tracking are set cor-
rectly, properly adjust the upper and lower
support bearings and guide-block assem-
blies into position before cutting opera-
tions.
