BLADE TENSION(FIG. L)
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.
