The chain is the heart of any chainsaw, and choosing the right one for the MS 260 Pro can significantly impact performance. I cannot emphasize enough how critical chain selection and maintenance are.

• Chain Types:
  • Full Chisel: Offers the fastest cutting speed but requires more frequent sharpening and is less forgiving in dirty wood.
  • Semi-Chisel: A good compromise between speed and durability, suitable for general use.
  • Micro-Chisel: Best for dirty or frozen wood, as it holds an edge longer but cuts slower.
• Chain Pitch and Gauge: Ensure you use a chain with the correct pitch (.325″) and gauge (.063″) for your MS 260 Pro.
• Sharpening:
  • File Size: Use a 5/32″ (4.0 mm) round file for sharpening .325″ pitch chains.
  • Angle: Maintain a consistent 30-degree angle for the top plate and a 10-degree down angle.
  • Depth Gauges: Check and adjust the depth gauges (rakers) to .025″ every few sharpenings.
• Maintenance:
  • Clean the chain regularly with a brush and solvent to remove pitch and debris.
  • Inspect for damage, such as cracks or broken teeth, and replace as needed.
  • Store chains in oil to prevent rust and corrosion.

Personal Story: I once spent an entire day struggling to cut through a seasoned oak log, only to realize my chain was not only dull but also had incorrectly filed depth gauges. After a proper sharpening and adjustment, the MS 260 Pro sliced through the oak like butter. This taught me a valuable lesson about the importance of chain maintenance.
