Blade Tensioner
The blade tensioner may need to be reset for one
of the following reasons:
•
The blade tension quick release lever will not
move to the right position when the tension
scale is correctly adjusted for the installed
blade.
•
You have installed a blade of a different
length and the tensioner needs tightened.
The procedure below describes how to decompress
the spring in the blade tensioner to allow the quick
release lever to perform its intended purpose. If
the tensioner needs tightened, reverse the proce-
dure to get the desired results.
Tools Needed
Wrenches 14mm ................................................ 2
To reset the blade tensioner:
1.

As the bandsaw ages, the rubber tires on the
wheels may need to be redressed if they harden or
glaze over. Redressing the rubber tires improves
blade tracking and reduces vibration/blade lead.
If the rubber tires become too worn, then blade
tracking will become extremely difficult because
wheel crown will lose their proper shape. At that
point, redressing will no longer be effective and
the rubber tires must be replaced.

Test the blade tensioner setting by moving
the quick release lever to the right.
Use the blade tensioner knob to final tension
the blade.
Repeat the procedure until the proper ten-
sion and release are achieve with the quick
release lever.
Note: Over compressing the spring will wear
it out prematurely, making the blade ten-
sioner sloppy and inaccurate. Only compress
the spring as needed to remove play in the
system.
Redressing
Rubber Tires
DISCONNECT MACHINE FROM POWER!
Put on heavy leather gloves.
Remove the blade.
Clean any built-up sawdust from the rubber
tires.
Hold 100-grit sandpaper against the rub-
ber tire and rotate the wheel by hand. Only
redress the rubber enough to expose a fresh
rubber surface.
