ADJUSTING
BLADE TENSION
Blades of 1/8 in., 1/4 in., and 3/8 in. in width by
59-1/2 in. 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.
WARNING: DISCONNECT MACHINE FROM
POWER SOURCE.
1. After the desired blade is assembled to the two
wheels, turn tension knob (A) Fig. 19, clockwise until
spring (B) begins to compress.
2. Turn tension knob (A) Fig. 19, an additional 2-1/2
turns for 1/8 in. wide blades; 3 turns for 1/4 in. wide
blades; and 4 turns for 3/8 in. wide blades.
3. A chart (C) Fig. 19, 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
WARNING: DISCONNECT MACHINE FROM
POWER SOURCE.
1. 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”
).
2. Open the hinged door (C) Fig. 20.
3. Rotate upper wheel (A) Fig. 20, 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. 19, 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. 21, should
always be no more than 1/8 in. above or as close as
possible to the top surface of the workpiece being cut.
Loosen knob (B) Fig. 21, rotate knob (C) and position the
guide assembly (A) to the desired position. Then tighten
knob (B).
