Chain Maintenance

Regular chain care ensures optimal performance and safety.

Chain Tension: Check before each use. Adjust via side tension screw until chain snaps back when pulled from bar.
Sharpening: Use round file matching chain pitch (usually 4.0mm). File at 30° angle. File all cutters evenly.
Lubrication: Ensure oil tank filled. Check oil flow by running saw near light surface; oil line should appear.
Bar Maintenance: Clean bar groove regularly. Flip bar monthly for even wear.
