Product Description

Features + Benefits

  • Large 20in. bar powered by a 4.4 HP, 64.1cc gas engine
  • IntelliCarb™ compensating carburetor automatically adjusts the air/fuel ratio to maintain proper engine RPMs even when the air filter becomes restricted or partially clogged
  • Side-access chain tensioner provides easy access allowing for easier chain adjustments with a bar wrench
  • Anti-vibration system minimizes vibration levels to increase comfort and help reduce user fatigue
  • Reduced emission engine technology produces zero or low exhaust emissions that are cleaner than EPA and/or CARB exhaust emission standards
  • Pre-separation air filtration system drastically reduces dirt particles that reach the engine air filter, resulting in less frequent air filter cleaning and maintenance
  • Toolless fuel and oil caps with retainers allow you to simply lift the lever ad twist the caps to remove or tighten, no tools necessary
