2.
Turn the upper wheel by hand a few times
and
notice
if
the blade remains
in
the
center
of
the tire
on the top
wheel.
If the blade moves away from the center of the
tire while you are turning it, the blade is
not
tracking properly.
The
top wheel shaft
is
hinged so the blade can
be
tracked. Tilt the wheel by turning the tracking
adjustment screw using a medium screw
driver.
(See
illustration.)
a.
If the
bladel. moves toward
the front of
the
band
saw:
Turn the tracking adjustment screw clockwise
about 1/4 of a turn, as though you
were
tightening
it.
b. If the blade moves toward the back of the band
saw:
Turn the tracking adjustment screw counter-
clockwise about 1/4 of a turn as though
you
were loosening it.
c. Check adjustment by turning wheel by hand.
3. The upper and lower blade guides support the
blade and keep it'f rom twisting during operation.
Adjust blade guide support whenever blades are
changed or replaced with a different width.
4. Push the blade guide support toward the
blade
and adjust the blade guides so they
are about
1/32-inch from the deepest part of th9
blade
teeth. This deep part
is
called a gullet. Tighten
the set screw locking the blade guide support.
Turn the upper wheel, by hand, checking the
position of the blade guide support.
NOTE: Letting the blade teeth hit the
blade
guides while using the band saw will ruin
the
blade. The
set of the teeth and the
sharpened
edge of the teeth would be damaged.
Proper
adjustment of the upper and lower blade guide
assemblies will prevent this from happening.
Repeat
procedure for lower blade guide support.
5. Slide the two blade guides evenly against the
sides of the blade. Do not push the blade guides
or pinch the blade guides against the blade.
Rotate the upper wheel by hand so the blade
travels downward. This leaves proper space for
blade. Make sure one guide
is
not further
from
the blade than the other. Tighten both setscrews
with a 1/8-inch hex "L" wrench_ Repeat proce-
(lure for lower blade guides.
NOTE: The backup bearings support the blade
from the rear and will spin
when
the
blade
is
pushed against them while you are cutting.
As
soon
as
you stop cutting, the
bearings should
stop spinning.
