G0457 14" Industrial Bandsaw (Mfg. Since 5/11)
Blade Tensioning
A properly tensioned blade is essential for mak-
ing accurate cuts and is a prerequisite for making
many bandsaw adjustments. The blade tension
scale shows the approximate tension, but the
steps below will allow you to get the optimum ten-
sion for the installed blade.
To tension the bandsaw blade:
1. Make sure you have completed the Test Run
procedure on Page 21 and that the blade is
tracking properly.
2. Raise the upper blade guide assembly as
high as it will go, and adjust the upper and
lower guide blocks as far away from the blade
as possible.
Note: This procedure will NOT work if the
guide blocks have any contact with the
blade.
3. Adjust blade tension until the mark on the
blade tension scale matches the size of the
installed blade.
Note: This scale can only be considered a
general guide. Complete the following steps
to accurately set blade tension.
4. Turn the bandsaw ON.
5. Slowly release the tension one quarter of a
turn at a time. When you see the bandsaw
blade start to flutter, stop decreasing the ten-
sion.
6. Now, slowly increase the tension until the
blade stops fluttering, then tighten the tension
another quarter turn.
7. Look at what the tension gauge reads and
use that as a guide for tensioning that blade
in the future.
Note: Always de-tension the blade after use
to increase blade life and reduce strain on the
bandsaw components.
NOTICE
After blade tension and tracking are set cor-
rectly, you MUST properly adjust the upper
and lower support bearings and guide-block
assemblies into position before cutting.
Adjusting Support
Bearings
The support bearings are positioned behind
the blade for support during cutting operations.
Proper adjustment of the support bearings is an
important part of making accurate cuts and also
keeps the blade teeth from coming in contact with
the guide bearings while cutting.
To adjust the support bearings:
1. Make sure that the blade is tracking properly
and that it is correctly tensioned.
2. DISCONNECT BANDSAW FROM POWER!
3. Familiarize yourself with the support bearing
controls shown in Figure 30.
