8. When the blade is around both wheels,
adjust the position so the back of the blade is
against the shoulder of the wheels.

Blade Tension
NOTICE
Loosen blade tension at the end of each day
to prolong blade life.
Proper blade tension is essential to long blade
life, straight cuts, and efficient cutting. The Model
G0613/14 features a blade tension indicator to
assist you with blade tensioning.
Two major signs that you do not have proper blade
tension are: 1) The blade stalls in the cut and slips
on the wheels, and 2) the blade frequently breaks
from being too tight.
To tension the blade on the bandsaw:
1. Locate the blade tension handle (Figure
36) and add a few drops of oil on the lead
screw.

2. Using the graduated scale on the blade ten-
sion indicator
(Figure 37) turn the blade
tension handwheel so the tension is in the
orange range when using the saw. When the
saw is not being used, adjust the tension to
the yellow range.

3. When the correct tension is reached, adjust
the tension stop bolt so when you need to
de-tension and re-tension the blade, the
handwheel will stop at your predetermined
tension setting.

Note: For carbon blades, the blade tension
should be 20,000 PSI. For bi-metal blades,
like the one supplied with your machine, the
blade should
be tensioned from 30,000 to
35,000 PSI.
If you are using a blade tensioning gauge, like
the one found in SECTION 5:

on Page 27, you will find the specifications
below useful. Follow the manual instruc

tions included with your gauge and the blade
manufacturer's recommendations on blade
tension.
