Blade Tracking

The blade tracking has been properly set at the factory. The tracking will rarely need to be adjusted if the bandsaw is used properly.

To adjust the blade tracking on the bandsaw, loosen or tighten the tracking adjustment bolt and lock nut in Figure 30 until the blade is tracking properly. The blade is tracking properly when the back of the blade is approximately 1⁄16" away from the flange of both wheels.

Blade Breakage

Many conditions may cause a bandsaw blade to break. Some of these conditions are unavoidable and are the natural result of the stresses placed on the bandsaw; other causes of blade breakage are avoidable.

The most common causes of avoidable blade breakage are:

•Faulty alignment or adjustment of the blade guides.

•Forcing or twisting a wide blade around a tight radius.

•Feeding the workpiece too fast.

•Dull or damaged teeth.

•Over-tensioned blade.

•Top blade guide assembly set too high above the workpiece. Adjust the top blade guide assembly so that there is approximately 1⁄8"–⁜1⁄4" between the bottom of the assembly and the workpiece. Understand that with smaller workpieces, this may not be possible. In these cases, simply adjust the blade guide as far down as possible.

•Using a blade with a lumpy or improperly fin- ished braze or weld.

•Continuously running the bandsaw when not in use.

•Leaving the blade tensioned when not in use.

•Using the wrong blade pitch (TPI) for the workpiece thickness. The general rule of thumb is to have no fewer than three teeth in contact with the workpiece when starting a cut and at all times during cutting.
