To Adjust The Blade Tracking
1. Raise the Bandsaw to its full vertical position,
making sure it locks in position by turning the
Cylinder's Feed Lock off. (See Figure I.)
2. Turn on the Bandsaw. The Saw Blade (251) is
tracking properly when the back of the Blade is
just touching the edge of the Idler Wheel (250S)
flange. The back of the Blade should not be
rubbing against the flange. (See Figure D.)
3. If adjustment is necessary, the Blade
Guide Bearings (266-10) should be clear
of the Saw Blade. (See Figure E.)
To Adjust The Blade Speed
Before use, change the Saw Blade (251) speed to suit the material being cut.
The chart below shows settings for several materials.
Stainless Alloy Steel
Bearing Bronze
Medium to High Carbon Steel
Hard Brass or Bronze
Low to Medium Carbon Steel
Soft Brass
Aluminum
Plastic
1. To adjust the Saw Blade speed, loosen the
two Nuts (304) and Screws (307-2). Slide the
Motor (300) forward to release tension
on the V-Belt (208). (See Figure G.)

4. Loosen the upper Hex Head Screw (243) to a point
where it is just barely snug. (See Figure D.)
5. With the Bandsaw running, turn the Adjusting Hex
Head Screw (240) until the Saw Blade is tracking
properly, making sure Blade tension is maintained
by turning the Blade Tension Knob (245) clockwise.
6. Retighten the upper Hex Head Screw
when adjustment is complete.

2. Remove the V-Belt from its two Pulleys (206, 296).
Place the V-Belt onto the two Pulleys according to
the Saw Blade speed desired. (See Figure F.)
3. Then move the Motor back to its original position
and secure in place by tightening the previously
loosened two Nuts and Screws. (See Figure G.)
4. Verify V-Belt tension by pressing the V-Belt
between the pulleys. Deflection should be
about 3/8". In time, the V-Belt will stretch
and loosen. Loosen the Nut (302) and back
off the V-Belt Tension Limiter Bolt (301).
5. Turn the V-Belt Tension Limiter Bolt
against the Motor Mount Bracket (307)
and tighten the Nut (302).
