8.When the blade is around both wheels, adjust the position so the back of the blade is against the shoulder of the wheels.

9.Reinstall the blade cover and the blade guide guards.

10.Now go to the Blade Tension procedure and set the blade tension.

Blade Tension

Proper blade tension is essential to long blade life, straight cuts, and efficient cutting. The Model G0613/14 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.

NOTICE

Loosen blade tension at the end of each day to prolong blade life.

To tension the blade on the bandsaw:

1.Locate the blade tension handle (Figure 36) and add a few drops of oil on the lead screw.

2.Using the graduated scale on the blade ten- sion indicator (Figure 37) turn the blade tension handwheel so the tension is in the orange range when using the saw. When the saw is not being used, adjust the tension to the yellow range.

Note: For carbon blades, the blade tension should be 20,000 PSI. For bi-metal blades, like the one supplied with your machine, the blade should be tensioned from 30,000 to 35,000 PSI.

If you are using a blade tensioning gauge, like the one found in SECTION 5: ACCESSORIES on Page 27, you will find the specifications below useful. Follow the manual instruc- tions included with your gauge and the blade manufacturer's recommendations on blade tension.

3.When the correct tension is reached, adjust the tension stop bolt so when you need to de-tension and re-tension the blade, the handwheel will stop at your predetermined tension setting. (Figure 38).
