A properly tensioned blade is essential for making accu-
rate cuts and is a prerequisite for making many bandsaw
adjustments. The blade tension is adjusted by rotating
the blade tension lever.
To tension the bandsaw blade:
1. Make sure you have performed the Test Run instruc-
tions on the previous page and you are certain that
the blade is tracking properly.
2. With the blade tension lever in the down (engaged)
position, adjust the blade tension until the indicator
on the blade tension scale ( Figure 23) matches the
size of blade installed on the bandsaw.
Note: Because each blade is different and all blades
stretch, this scale is only an approximation. Always
measure blades from the tip of the tooth to the
back of the blade.
3. Turn the bandsaw ON.
4. Release the tension one quarter of a turn at a time.
When the bandsaw blade starts to flutter, stop
decreasing the tension.
5. Now, slowly increase the tension until the blade
stops fluttering, then tighten the tension one more
quarter of a turn.
6. Turn the bandsaw OFF and read the tension gauge.
Use the reading as a guide when tensioning that
blade in the future.
Note: Do not rely on this measurement for long
periods of time because the blade will stretch with
use, making the tension gauge slightly inaccurate.
Blade Tensioning
NOTICE
To reduce blade stretching, remove
the tension from the blade when not
in use.
NOTICE
After blade tension and tracking are set
correctly, properly adjust the upper/
lower support bearings and guide-block
assemblies into position before operat-
ing machine.
