" x 10" Metal-Cutting Bandsaw
-31-
It is always a good idea during the life of your saw
to check and adjust this setting. This adjustment
will improve your cutting results and extend the
life of your blade.
To square the blade to the bed of the table:
1.
UNPLUG THE BANDSAW!
2.
Lower the head of the bandsaw all the way
until it contacts the horizontal stop.
3.
Place a square on the table bed and against
the edge of the blade (
Figure 43
), and check
different points along the length of the table
between the blade guides.
4.
Loosen the cap screws shown in
Figure 43
,
and rotate the blade guide until the blade
is vertical to the bed, then tighten the cap
screws.

Blade Tension
Proper blade tension is essential to long blade life,
straight cuts, and efficient cutting times.
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.
Make sure the blade is tracking properly.
2.
UNPLUG THE BANDSAW!
3.
Loosen and slide the blade guides as far
apart as they will go, then tighten them down
again.
4.
Turn the tension knob in
Figure 42
clockwise
to tighten the blade.

5.
Using moderate finger pressure, push against
the side of the blade. The blade should
not move more than 0.040"–0.050" (1.0mm-
1.2mm). This is an adjustment done by feel
and experience more than anything. You
want to find that fine line between the blade
slipping off the wheel and breaking blades
from too much tension.
6.
Another option is to use a blade tensioning
gauge, like the one found in
