TROUBLESHOOTING
GUIDE
POSSIBLE CAUSE
CORRECTIVE ACTION
1. Clamp work securely.
2. Adjust speed or feed.
3. Replace with a small teeth spacing blade.
4. Use a blade of slow speed and small teeth spacing.
5. Adjust to where blade just does not slip on wheel.
6. Place blade in contact with work after motor is
started.
7. Adjust wheel alignment.
8. Adjust guide bearings.
9. Use thinner blade.
10. Weld, note the welding skill.
1. Use finer teeth.
2. Decrease speed.
3. Decrease feed rate.
4. Reduce speed, increase feed rate.
5. Increase feed rate by tightening spring handle.
6. Replace with a new blade, and adjust blade tension.
7. Replace.
8. Tighten blade tension.
1. Replace.
2. Adjust as per instruction manual.
3. Tighten.
1. Use finer tooth blade.
2. Decrease fee rate, increase speed.
3. Clamp workpiece securely.
4. Use coarser tooth blade or brush to remove chips.
1. Reduce tension on blade.
2. Reduce tension on drive belt.
3. Use finer blade.
4. Use coarse blade.
5. Adjust gears so that worm is in center of gear.
6. Check oil level, refill using SAE 80W90 differential oil.
7. Decrease feed rate.
1. Increase feed rate by loosening spring handle.
2. Adjust blade guides; the clearance cannot be greater
than 0.001".
3. Increase blade tension by adjusting blade tension.
4. Replace blade.
5. Adjust speed.
6. Adjust guide space.
7. Tighten.
8. Readjust blade tracking.
1. Reduce blade speed or the feed rate.
2. Replace with finer blade.
