Clean the
bandsaw.
High Examine the bandsaw for chip build-up between the
blade and it's wheels. If necessary, clean it of chips.
For information, see "Machine
Maintenance" (page45).
Adjust the feed
rate.
High Verify that the feed rate isn't too high: lower the feed
rate, and then do a test cut. Examine the behavior of
the machine as it cuts.
For information, see "Change the
Feed Rate" (page34).
Raise the
vertical quick-
adjustment nut.
High During automatic operation, verify that the blade can't
collide with the material while it initially lowers: raise
the vertical quick-adjustment nut. The blade can break
or stall when it drops from the raised position and then
collides with the part before the feed rate is controlled.
For information, see "Use
Automatic Mode" (page38).
Examine the
blade, material,
and size of cut.
High Verify that the blade's TPI isn't too fine or too course
for the size and type of material being cut. If not, you
may need to choose a new blade.
Verify that the blade isn't dulling too quickly.
For information, see "Choose a
Blade" (page30) and "Blades Dull
Too Quickly" (page53).
Adjust the
blade's tension.
Medium Verify that the blade isn't too tight or too loose
between the wheels. If necessary, use the tensioner on
the top of the saw head to adjust the blade's tension.
For information, see "Change a
Blade" (page30).
Move the blade
above the
workpiece.
Medium During manual operation, verify that the blade isn't on
the workpiece when the operation begins: you must
move the blade above the workpiece before you begin
cutting.
For information, see "Use Manual
Mode" (page42).
Examine the
workpiece setup.
Low
l
Manual Operation Verify that the workpiece
isn't too loose: use the handwheel to tighten the
clamp on the front vise. If necessary, use a jig to
hold the workpiece.
l
Automatic Operation Examine the vise clamps:
verify that there is 1/8 in. or less of a gap
between the clamps and the material. Then,
verify that the vise jaw clamping pressure isn’t
set too low for the material.
For information, see "Use
Automatic Mode" (page38) or "Use
Manual Mode" (page42).
Verify that the
blade doesn't
rub on the wheel
flange.
Low Verify that the blade isn't incorrectly tracking so that it
runs directly against the wheel flange during
operations. Follow the procedure to adjust the blade
tracking.

Adjustments.
