STOP
REMEDY
1. Use band with finer teeth
2. Reduce feed pressure, increase speed
3. Fix workpiece firmly in place
4. Use band with coarser teeth
1. Reduce tension on band
2. Use fine band
3. Use coarse band
4. .Adjust gearbox such that the worm is in
the middle of the gearbox
5. Check oil level
6. Reduce speed
1. Reduce pressure by increasing spring
tension on the side of the saw
2. Adjust guide bearings, the spacing should
be no more than 0.1 mm
3. Increase band tension
4. Replace saw band
5. Adjust speed
6. Adjust spacing of band guides
7. Tighten
8. Adjust as per operating instructions
1. Reduce speed or feed
2. Replace with finer band
3. Adjust band tension
1. Reduce feed
2. Reduce band tension
1. Press and reset emergency/off button
2. Check upper limit switch and position
Ensure that the limit switch is located
below the rail at all times
3. Check hydraulic oil level; ensure that the
oil level is as it should be
4. Check motor revolutions; ensure that
