ADJUSTING BLADE
TENSION
The band saw is equipped with a quick tensioning blade
mechanism. To apply tension, move the tension handle
(A) to the left as shown. To release tension, move the
tension lever lock (B) Fig. 49 up, and move the tension
handle (A) to the right as shown in Fig. 50.
To adjust the blade tension proceed as follows:

6. The band saw blade tension can be fine tuned by
turning adjustment nut (N) Fig. 51, while the blade is
tensioned.
7. A series of graduations is located on the back of the
upper wheel slide bracket (T) Fig. 51. These graduations
indicate the proper tension for various widths of blades.
NOTE: THESE GRADUATIONS ARE CORRECT FOR
AVERAGE WORK, AND WILL NOT BE AFFECTED BY
REBRAZING OF THE SAW BLADE.
WHEN CUTTING THIN PIECES, 3/4" OR
LESS, SET THE BLADE TENSION BELOW THE
MAXIMUM SETTING FOR BLADE WIDTH, TO
EXTEND BLADE LIFE.
OVER-STRAINING IS A COMMON CAUSE
OF BLADE BREAKAGE AND OTHER UNSATISFACTORY
BLADE PERFORMANCE. RELEASE THE TENSION
WHEN THE TOOL IS NOT IN USE.
