21TroubleshootingFaultExcessive bladebreakagePremature bladedullingBad cuts(out-of-square)Bad cuts (rough)Probable cause1. Material loose in vise.2. Incorrect speed or feed.3. Teeth too coarse for material.4. Incorrect blade tension.5. Saw blade contacts workpiecebefore the saw is started.6. Blade rubs on the wheel flange.7. Misaligned guides.8. Cracking at weld.1. Blade teeth too coarse.2. Blade speed too high.3. Hard spots in workpiece or scaleon/in workpiece.4. Work hardening of material(especially stainless steel).5. Insufficient blade tension.6. Operating saw without pressureon workpiece.1. Feed pressure too fast.2. Guide bearings not adjustedproperly.3. Inadequate blade tension.4. Dull blade.5. Incorrect blade speed.6. Blade guide assembly is loose.7. Blade guide bearing assemblyloose.8. Blade track too far away fromwheel flanges.9. Guide bearing worn.1. Blade speed too high for feedpressure.2. Blade is too coarse.Suggested remedy1. Clamp work securely.2. Refer to Figure 6 or checkMachinist’s Handbook for speed/feed appropriate for the materialbeing cut.3. Check Machinist’s Handbook forrecommended blade type.4. Adjust blade tension to the pointwhere the blade just does not slipon the wheel.5. Start the motor before placing thesaw on the workpiece.6. Adjust blade tracking.7. Adjust guides.8. Longer annealing cycle.1. Use a finer tooth blade.2. Try a lower blade speed.3. Increase feed pressure (hardspots). Reduce speed, increasefeed pressure (scale).4. Increase feed pressure by reduc-ing spring tension.5. Increase tension to proper level.6. Do not run blade at idle in/onmaterial.1. Decrease pressure.2. Adjust guide bearing clearance to0.001 inch (0.002 inch maximum).3. Gradually increase blade tension.4. Replace blade.5. Check blade speed(see Figure 6).6. Tighten blade guide assembly.7. Tighten blade guide bearingassembly.8. Adjust blade tracking.9. Replace worn bearing.1. Reduce blade speed and feedpressure.2. Replace with finer blade.
