Blade 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.
to adjust the blade tracking on the bandsaw,
loosen or tighten the tracking adjustment bolt and
lock nut in
figure 30
until the blade is tracking
properly. the blade is tracking properly when the
back of the blade is approximately
1
⁄
16
" away from
the flange of both wheels.

Many conditions may cause a bandsaw blade to
break. some of these conditions are unavoidable
and are the natural result of the stresses placed
on the bandsaw; other causes of blade breakage
are avoidable.
the most common causes of avoidable blade
breakage are:
•
Faulty alignment or adjustment of the blade
guides.
•
Forcing or twisting a wide blade around a
tight radius.
•
Feeding the workpiece too fast.
•
dull or damaged teeth.
•
over-tensioned blade.
•
top blade guide assembly set too high above
the workpiece. adjust the top blade guide
assembly so that there is approximately
1
⁄
8
"–
1
⁄
4
" between the bottom of the assembly
and the workpiece. understand that with
smaller workpieces, this may not be possible.
in these cases, simply adjust the blade guide
as far down as possible.
•
using a blade with a lumpy or improperly fin-
ished braze or weld.
•
Continuously running the bandsaw when not
in use.
•
leaving the blade tensioned when not in
use.
•
using the wrong blade pitch (tpi) for the
workpiece thickness. the general rule of
thumb is to have no fewer than three teeth
in contact with the workpiece when starting a
cut and at all times during cutting.
