Proper blade tension is essential to long blade life, straight cuts, and efficient cutting. The Model G9743 features a blade tension indicator to assist you with blade tensioning.
Two major signs that you do not have proper blade tension are: 1) the blade stalls in the cut and slips on the wheels, and 2) the blade frequently breaks from being too tight.
To tension the blade on the bandsaw:
1.Make sure the blade is tracking properly.
2.UNPLUG THE BANDSAW!
3.Slide the blade guides as far apart as they will go, then tighten them down again.
4.Turn the tension handle clockwise to tighten the blade.
5.Tighten the blade until the tension indicator moves into the green or center section of the indicator.
6.To fine tune blade tension, use a blade tensioning gauge, like the one found in SECTION 5: ACCESSORIES on Page 26. Please follow the instructions included with your gauge and the blade manufacturer's recommendations on blade tension.
It is always a good idea during the life of your saw to check and adjust this setting. This adjustment will improve your cutting results and extend the life of your blade.
To square the blade to the bed of the table:
1.UNPLUG THE BANDSAW!
2.Lower the head of the bandsaw all the way until it contacts the horizontal stop.
3.Place a square on the table bed and against the edge of the blade (Figure 38), and check different points along the length of the table between the blade guides.
4.Loosen the cap screw shown in Figure 38, and rotate the blade guide until the blade is vertical to the bed, then tighten the cap screws.
Note: Both blade guides can be adjusted to achieve the results you want.
