BLADE TENSiON (FIG.

M)

A WARNING

To avoid injury, turn the switch OFF and disconnect the saw
from the power source before making any adjustments,
NEVER make tension adjustments with the machine running.

The gauge (1) on the bracket (2) at the rear of the upper
wheel housing indicates the proper tension for the various
blade widths,

1. Set the blade tension gauge to correspond with the width

of the blade in use,

2. Turn the blade tension knob (3) clockwise, raising the

upper wheel to tighten the blade. Turn the knob
counterclockwise to lower the upper wheel, loosening

the blade.

3. As you become familiar with the saw, you may want to

change the tension settings.

NOTE: Changes in blade width and type of material
being cut will have an effect on the blade tension. Too
much or too little tension could break the blade. When
the band saw is not in use, relax the blade tension.

BLADE TRACKING (FIG. N)

To avoid injury, turn the switch OFF and disconnect the saw
from the power source before making any adjustments.

NEVER make tension adjustments with the machine running.

1. The blade (1) must be tensioned properly before

adjusting the tracking.

2. Open the upper cover.
3. Move the blade guides (2) and support bearings (3)

away from the blade, if necessary. See page 15 for
bearing and guide adjustment.

4. Rotate the wheel (4) slowly forward by hand, and check

the position of the blade on the wheel. The blade should
remain centered on the wheel as it turns.

If the blade moves toward the front of the wheel, turn the

tracking knob (5) on the rear of the band saw clockwise.
This tilts the top of the wheel and moves the blade
toward the center.

If the blade moves toward the back edge, turn the

tracking knob counterclockwise, moving the blade toward
the center.

NOTE: Turn the tracking knob SLIGHTLY to make blade
tracking adjustments.

To avoid injury, turn the switch OFF and disconnect the saw
from the power source before making any adjustments.
NEVER make adjustments with the machine running.

1. Loosen the lock knob (1} and move the blade guide

assembly (2) up or down to 1/8" above the workpiece.

2, Tighten the lock knob.
