GENERAL

Problem

Blade does not run in the center of the

upper wheel.

Band saw slows down when cutting.

Probable Cause

1.Not tracking properly.

2.Defective blade.

1.Belt too loose•

2.	Cutting too small a radius.
3.	Dull blade.
4.	Overloading motor.

Remedy

1.Adjust tracking. See ASSEMBLY AND ADJUSTMENTS section "BLADE TRACKING".

2.Replace blade.

1.Adjust belt tension. See ASSEMBLY AND ADJUSTMENTS section "BLADE TENSION".

2.	Stop feeding, back up the material	slightly, until the
	band saw speeds up.
3.	Replace blade.
4.	Slow down, you are trying to cut too fast. See
	"MOTOR TROUBLESHOOTING	GUIDE".

Blades braking.

1. Too much tension on

the blade•

2.Kink in the blade caused by cutting too small a radius or turning the material too fast when cutting.

1. Adjust tension. See ASSEMBLY AND

ADJUSTMENTS section "BLADE TENSION"

2.Use correct cutting technique.

See OPERATION section "GENERAL CUTTING".

Motor fails to develop full power.

Motor overheats•

1, Low line voltage.

2. Faulty motor or capacitor.

. Overload on motor.

2.Poor ventilation of motor. Provide better air circulation.

3.Capacitor failure.

1.Check power line for proper voltage.

2.Take to Sears Service Center for evaluation.

1.	Reduce load		to motor, feed work slower into blade•
2.	Unplug	and	clean out around motor; provide
	better	air circulation.
3.	Take to Sears Service Center for repair•

Blade dulls too quickly.

Band saw vibrates.

Motor stalls or slows•

1• Motor overload.

2.Low line voltage.

3.Loose wire connections•
