Cutting Techniques

Proper cutting methods for different applications.

1. Felling trees: Plan escape path, make notch cut 1/3 of tree diameter, make felling cut leaving hinge.
2. Limbing: Work from trunk to top, stand on opposite side of tree, cut downward branches first.
3. Bucking: Support log properly, cut from top, avoid cutting into ground.
4. Pruning: Use pulling chain (bottom of bar) for better control, make relief cuts for heavy branches.

WARNING! Beware of kickback zone (upper quadrant of bar tip). Never cut with tip. Maintain firm grip with thumbs wrapped around handles.

Maintenance Schedule

Daily, weekly, and monthly maintenance tasks.

Chain Sharpening

Proper chain sharpening procedure.

1. Secure bar in vise or clamp.
2. File each cutter with round file matching chain pitch (typically 5/32" or 4.0mm).
3. Maintain 30° filing angle, file from inside to outside.
4. File all cutters to same length for balanced cutting.
5. Check depth gauges with depth gauge tool, file down if too high.
6. Lubricate chain after sharpening.

CAUTION! Always wear gloves when handling chain. Ensure file is proper size for chain.

Storage Guidelines

Proper storage procedures for extended periods.

1. Drain fuel tank completely or add fuel stabilizer.
2. Run engine until carburetor is empty.
3. Remove chain, clean and soak in oil, store separately.
4. Clean entire saw, especially air intake and cooling fins.
5. Store in dry place, cover to prevent dust accumulation.

Tip: Store bar horizontally to prevent warping. Lubricate all moving parts before storage.
