G0592 Metal Cutting Bandsaw
-35-
Note: It is sometimes possible to flip the
blade inside out, in which case the blade will
be installed in the wrong direction. Check to
make sure the blade teeth are facing toward
the workpiece, as shown in
Figure 44, after
mounting on the bandsaw. Some blades will
have a directional arrow as a guide.
8. When the blade is around both wheels,
adjust the position so the back of the blade is
against the shoulder of the wheels.
9. Complete the blade change by following the
steps in the next section, Blade Tension &
Tracking.
Figure 44. Blade cutting direction.
Blade Tension &
Tracking
The blade tracking has been properly set at
the factory. The tracking will rarely need to be
adjusted if the bandsaw is used properly. The
blade is tracking properly when the back of
the blade is lightly touching the flange of both
wheels.
To adjust the blade tracking on the bandsaw:
1. Turn the tracking set screw (hidden from
view) in
Figure 45 until the blade is tracking
properly.

Blade Tension Guide
NOTICE
Loosen blade tension at the end of each day
to prolong blade life.
To tension the blade on the bandsaw:
1. Turn the blade tension handle clockwise to
tension the blade.
2.
Use the graduated scale on the blade tension
indicator (Figure 45) to determine blade ten-
sion in PSI.
—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.
3. To fine tune blade tension, use a blade
tensioning gauge, like the one found in
SECTION 5:
ACCESSORIES on Page 28.
Please follow the instructions included with
your gauge and the blade
manufacturer's
recommendations on blade tension
.
Proper blade te
nsion is essential to long blade
life, straight cuts, and efficient cutting. The Model
G0592 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.
