CORRECTIVE ACTION
1. Adjust vise to be square with blade
2. Reduce pressure by increasing spring tension
3. Adjust guide bearings
4. Increase blade tension a little at a time
5. Move guides as close to work as possible
6. Replace blade
7. Check pages 9 and 10 for recommended
speeds
8. Tighten
9. Tighten
10. Track blade properly according to
instructions under Operation, page 9
11. Replace
1. Reduce speed or feed
2. Replace with finer tooth blade
1. Decrease feed pressure
2. Replace
3. Adjust guide bearings (see page 8)
4. Tighten bearings
5. Reduce feed pressure
1. Check electrical wiring to motor for
continuity
2. Check power line for proper voltage
3. Replace defective parts before using band
saw again
4. Inspect lead terminals on motor for loose or
open connections
5. Reset protector after motor has cooled
6. Any attempt to repair this motor may create a
hazard unless repair is done by an authorized
qualified technician. Replacement motors are
available
1. Inspect line cord or plug for damaged
insulation and shorted wires
2. Inspect all lead terminals on motor for loose
or worn insulation on wires
3. Install correct fuses or circuit breakers
4. Reduce load on motor
1. Reduce the load on the power line
2. Increase wire sizes or reduce length of cords
3. Request a voltage check from the power
company
1. Reduce load on motor
2. Clean motor to provide normal air circulation
around motor
