Blade Tension; Squaring The Blade - Grizzly G9743 Owner's Manual

Blade Tension

Proper blade tension is essential to long blade
life, straight cuts, and efficient cutting. The Model
G9743 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:
Make sure the blade is tracking properly.
1.
UNPLUG THE BANDSAW!
2.
Slide the blade guides as far apart as they
3.
will go, then tighten them down again.
Turn the tension handle clockwise to tighten
4.
the blade.
Tighten the blade until the tension indicator
5.
moves into the green or center section of the
indicator.
To fine tune blade tension, use a blade
6.
tensioning gauge, like the one found in
SECTION 5: ACCESSORIES on Page 26.
Please follow the instructions included with
your gauge and the blade manufacturer's
recommendations on blade tension.

Squaring the Blade

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:
UNPLUG THE BANDSAW!
1.
Lower the head of the bandsaw all the way
2.
until it contacts the horizontal stop.
Place a square on the table bed and against
3.
the edge of the blade (Figure 38), and check
different points along the length of the table
between the blade guides.
Loosen the cap screw shown in Figure 38,
4.
and rotate the blade guide until the blade
is vertical to the bed, then tighten the cap
screws.
Note: Both blade guides can be adjusted to
achieve the results you want.
