Dispose of fuel: Do not store fuel mix more than 30 days.

Tip: Never use straight gasoline or motor oil. Never mix fuel near open flame.

Cutting Techniques

Basic cutting methods for safe operation.

Felling trees: Plan escape path, make notch cut, then felling cut. Use wedges if needed.
Limbing: Cut branches from bottom to top, use saw as support.
Bucking: Support log, cut from top, avoid cutting into ground.
Pruning: Cut small branches with one hand, larger with two.
Kickback prevention: Keep saw at full throttle, avoid tip contact.

WARNING! Always cut at waist level or below. Never cut with the upper tip of the bar.

Safety Features

Chain Brake: Inertia-activated; stops chain within milliseconds if kickback occurs. Anti-Vibration: Rubber mounts reduce vibration. Throttle Lockout: Must be pressed to engage throttle. Right Hand Guard: Protects from rear kickback. Chain Catcher: Prevents broken chain from striking operator.

Maintenance & Storage
