Tensioning Blade
A properly tensioned blade is essential for mak- ing accurate cuts and is a prerequisite for making many bandsaw adjustments.
To tension the bandsaw blade:
1.Make sure that you have performed the Test Run instructions on the previous page and that the blade is tracking properly.
2.With the blade tension lever in the down (engaged) position, adjust the blade ten- sion so the mark on the blade tension scale matches the size of blade that is installed on the bandsaw.
Note: Because each blade is different and all blades stretch, this scale can only be consid- ered as a general guide.
3.Turn the bandsaw ON.
4.Release the tension one quarter of a turn at a time. Do this very slowly. When you see the bandsaw blade start to flutter, stop decreas- ing the tension.
5.Now, slowly increase the tension until the blade stops fluttering, then tighten the tension one more quarter of a turn.
6.Look at what the tension gauge reads and use that as a guide for tensioning that blade in the future.
Note: However, do not rely on this measure- ment for long periods of time because the blade will stretch with use.
NOTICE
To reduce blade stretching, remove the ten- sion from the blade when not in use.
NOTICE
After blade tension and tracking are set cor- rectly, properly adjust the upper/lower sup- port bearings and

Bearings
The support bearings are positioned behind the blade and support the back of the blade dur- ing 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 18.
