ADJUSTING BLADE TENSION
Blades of 1/8", 1/4", and 3/8" in width by 59-1/2" in
length are available for use with your band saw. NOTE:
The blade tension must be adjusted to accommodate
different blade widths in order to provide proper blade
tracking, cutting performance, and blade life.

1. To install the desired blade, loosen screw (E) Fig. 25
with 5mm hex wrench provided and turn the tension knob
(A) Fig. 24, clockwise until the spring (B) begins to
compress.
2. Turn the tension knob (A) Fig. 24 an additional 2-1/2
turns for 1/8" wide blades; 3 turns for 1/4" wide blades;
and 4 turns for 3/8" wide blades. Tighten the screw (E)

TRACKING THE BLADE
DISCONNECT MACHINE FROM POWER
SOURCE.
1. Before tracking the blade, make sure that 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”).
2. Open the hinged door (C) Fig. 25.
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, turn the blade
tracking knob (D) Fig. 24 and/or Fig. 26, clockwise to
move the blade to the rear, and counterclockwise to
move the blade to the front. NOTE: Turn the blade
tracking knob (D) in small intervals to adjust the blade
tracking.
