• IntelliCarb™ Compensating Carburetor - The IntelliCarb™ Compensating Carburetor measures the air pressure on the clean side of the air filter and adjusts the metering diaphragm in the carburetor. This keeps the RPM at a consistent level, even when the air filter begins to clog.
• Bike Handle - When used in conjunction with a harness, the bike handle allows the machine to be easily guided, enabling a smooth horizontal mowing action to cover large areas quickly and efficiently. With soft grips for increased comfort, the bike handle provides greater control and helps reduce operator fatigue.
• Anti-Vibration System - STIHL has a system for minimizing the vibration levels of handheld outdoor power equipment. The STIHL anti-vibration system helps reduce operator fatigue and provides a more comfortable working experience.
• Shoulder Strap / Carrying System - Using a shoulder strap or carrying system helps distribute the weight of the equipment for increased operator comfort and improved maneuverability.
• Tool-Free Handle Adjustment - The central wing nut enables easy adjustment without the use of tools. For transportation and space-saving storage, the handle can be rotated 90°.
• Multi-Function Control Handle - Having easy access to all of the controls on one comfortable handle makes it easy to complete tasks so the operator’s hand never has to leave the handle.
• Semi-Automatic Choke Lever - The semi-automatic choke lever enables the simplified three-step start procedure, saving users time and allowing them to start jobs faster.
• Simplified Starting Procedure - To get started, users simply pump the fuel primer, set the choke, and pull the starter cord.

The tool will be ready to start again when the user is ready to get back to work.

• Purge Pump Primer - By pressing the bulb, this small fuel pump delivers fuel to the carburetor, reducing the number of starting pulls needed after an extended break between uses.
• Upright Translucent Fuel Tank - Easily check the fuel level before starting work. If fuel is needed, the upright position makes the tank easier to fill.
• Fully-Lined Drive Shaft - A lined shaft provides smooth operation and less vibration.
• Throttle Trigger Interlock - This safety feature must be depressed before the trigger can be activated.
• Reduced-Emission Engine Technology—Caring for Nature - The STIHL Inc. “Caring for Nature” seal identifies its powered products that are more environmentally conscious, producing zero or low exhaust emissions.
