ADJUSTING BLADE TENSION
Blades of 1/8", 1/4", and 3/8" in width by 72-1/2" 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.
Disconnect machine from power source.
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) Fig. 25.
3. A chart (C) Fig. 24 is located at the rear of the band
saw. This chart shows blade size, and the minimum
radius that can be cut with each size blade.

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.

ADJUSTING UPPER BLADE GUIDE
ASSEMBLY
The upper blade guide assembly (A) Fig. 26 should al-
ways be no more than 1/8" above or as close as possible
to the top surface of the workpiece being cut. Loosen
knob (B), rotate knob (C) and position the guide assembly
(A) to the desired position. Then tighten the knob (B).
