ADJUSTING
BLADE TENSION
Blades of 1/8", 1/4", and 3/8" wide by 59-1/2" in length
are available for use with your band saw. NOTE: The
blade tension must be adjusted to accommodate
differ-
ent blade widths in order to provide proper blade track-
ing, cutting performance
and blade life.
1.
DISCONNECT THE MACHINE FROM THE POWER
SOURCE.
2.
After the desired blade is assembled to the two band
saw wheels, turn tension knob (A) Fig. 24, clockwise until
spring (B) begins to compress.
3.
Turn tension knob (A)Fig. 24, an additional
2-1/2
complete turns for 1/8" wide blades; 3 complete turns for
1/4" wide blades; and 4 complete turns for 3/8" wide
blades.
4.
There is a convenient chart (C) Fig. 24, at the rear of
the band saw displaying blade choice and the minimum
radius which can be cut with each blade.

TRACKING THE BLADE
1.
DISCONNECT THE MACHINE FROM THE POWER
SOURCE.
2.
Before tracking
the blade, make sure the blade
guides and blade support bearings are clear of the blade
so as not to interfere with the tracking adjustment.
Also
make sure that the blade is tensioned properly. (Refer to
section "ADJUSTING
BLADE TENSION").
3.
Rotate upper wheel (A) Fig. 25, clockwise
by hand
and check to see if the blade (B) rides true on the
approximate
center of the two wheels.
4.
If an adjustment is necessary, SLIGHTLY turn blade
tracking
knob (D) Fig. 24, clockwise
to move the blade
to the rear, and counterclockwise
to move the blade to
the front. NOTE: Very little movement of the blade track-
ing adjusting knob (D) is necessary to permit the blade
to move.

UPPER
BLADE GUIDE ASSEMBLY
The upper blade guide assembly
(A)Fig. 26, should
always be no more than 1/4" above or as close as pos-
sible to the top surface of the workpiece
being cut.
Loosen knob (B) Fig. 26, rotate knob (C) and position the
guide assembly (A)to the desired position. Then tighten
knob (B).
