Causes:

• Dull blade
• Rocks, dirt, or debris embedded in bark
• Pushing the saw too fast
• Nails or hardware inside the log (hidden under bark)

Solutions:
✓ Debark your logs if they are dirty or muddy — even clean-looking logs contain dirt
✓ Use a debarking tool or clean the log manually
✓ Inspect for nails, staples, fencing, insulators, etc. and remove them
✓ Slow down your feed rate
✓ Watch for dirt/rocks in bark and remove them
✓ Clean/replace the air filter
✓ Sharpen/replace the blade
