4. Limbing: Cut from trunk outward, support limb if possible.
5. Bucking: Support log off ground; cut from top down.
6. Kickback Prevention: Avoid upper quadrant of bar tip; maintain secure grip.
7. After Cut: Allow chain to stop before moving saw.

WARNING! Always cut at waist level or below. Never operate above shoulder height.

Safety Features

Chain Brake: Inertia-activated; stops chain if kickback occurs. Throttle Lockout: Must be depressed before throttle engages. Right-Hand Guard: Protects from debris. Anti-Vibration: Reduces fatigue. Stop Switch: Immediate engine shut-off.

Care & Maintenance

Clean after each use. Check chain tension frequently. Sharpen chain when dull.

1. Air Filter: Clean every 5 hours; replace if damaged.
2. Spark Plug: Check gap (0.025"); replace every 100 hours.
3. Chain Sharpening: Use round file matching chain pitch; maintain 30° angle.
4. Bar Maintenance: Clean bar groove; flip bar weekly for even wear.
5. Storage: Drain fuel or add stabilizer; store in dry place.

CAUTION! Disconnect spark plug before performing maintenance. Use only genuine parts.
