Description:

The STIHL® FS 311 trimmer combines the best of all worlds—so you can better trim yours. Featuring a powerful, fuel-efficient engine, this trimmer works longer with fewer refuels compared to previous models. It includes a vertical pleated air filter for excellent air filtration and long service intervals. A simplified starting procedure helps you jump into your job faster, while its newly designed bike handles provide a comfortable grip of product while you work. The FS 311 also features the IntelliCarb™ compensating carburetor for optimal engine performance, as well as a four-point anti-vibration system for enhanced comfort. This trimmer accepts a range of metal cutting attachments and circular saw blades that can be used with the appropriate accessory kit (sold separately). This is one well-rounded performer.

Features:

• IntelliCarb™ Compensating Carburetor
• The IntelliCarb™ system measures air pressure on the clean side of the air filter and adjusts the metering diaphragm in the carburetor. This helps maintain consistent engine RPM, even as the air filter becomes clogged.
• Bike Handle
• Used with a harness, the bike handle allows for smooth, horizontal mowing to cover large areas efficiently. Soft grips enhance comfort and control while reducing operator fatigue.
• Anti-Vibration System
• The STIHL® anti-vibration system minimizes vibration in handheld equipment to help reduce operator fatigue and provide a more comfortable working experience.
• Shoulder Strap / Carrying System
• Distributes the equipment's weight for increased comfort and maneuverability, allowing for extended operation with less strain.
• Tool-Free Handle Adjustment
• A central wing nut enables quick handle adjustments without tools. For transport and compact storage, the handle can be rotated 90°.
• Multi-Function Control Handle
• All essential controls are conveniently located on one comfortable handle, so the operator’s hand never has to leave the handle during operation.
• Semi-Automatic Choke Lever
• Enables a simplified, three-step start procedure—saving time and getting the operator to work faster.
