Adjusting the saw blade tension
DANGER!
The saw blade tension must be checked before each
use!
WARNING!
Excessive saw blade tension can cause saw blade
breakage and serious injury.
Too low a saw blade tension can lead to slippage of
the tape guide rollers and thus to the standstill of the
saw blade.
Therefore always pay attention to a correct setting of
the saw blade tension!
Step 1: Turn the handwheel to increase or decrease the
saw blade tension via a spring. Turn the adjust-
ment knob clockwise to increase the blade ten-
sion. Turning the knob counterclockwise decrea-
ses the blade tension. Check the setting on the
blade voltage gauge. The scale indicates the
correct setting depending on the band saw blade
width.

NOTE!
After completion of the working shift, the saw band is
to be released again with the rotary knob.
NOTE!
Check the tension by pressing your finger halfway
between the table and the top guide against the side
blade.
The ideal tension is about 2mm.

Adjusting the saw band tension indicator
The blade tension indicator can be adjusted for blades
that are known to be cut over / under length by different
manufacturers. If the blade is moderately tensioned, loo-
sen the locking screw and raise or lower the blade indi-
cator as needed. Tighten the set screw again.

dial to adjust the height. Then retighten the loc-
king wheel (Fig.51).
