  3. Kickback Prevention: Never cut with upper tip of bar; be aware of wood tension.
  4. Shutting Down: Release throttle, press stop switch.

WARNING! Always operate with both hands. Never cut above shoulder height. Watch for falling branches.

Chain Maintenance

Regular maintenance ensures optimal performance and safety.

  1. Chain Sharpening: Use round file matching chain pitch; maintain 30° cutting angle.
