This powerful gas trimmer is designed with an easy-to-adjust bike handle and a semi-automatic choke lever.
Equipped with a simplified starting procedure, the FS 251 is a heavy-duty trimmer built for pros with no time to waste. Designed with a powerful low exhaust emission engine, the FS 251 saves on fuel and operating costs without losing any of the power. The FS 251’s easy-to-adjust bike handles provide comfort and ease while tackling widespread, overgrown areas. With a rugged design that offers optimal maneuverability and a vertically-pleated paper air filter that provides an extended service life, you can get to work quicker and count on the gas trimmer to last longer.
Features may include:
- Powerful Low Exhaust Emission Engine - A powerful low exhaust emission engine saves users fuel and operating costs without losing the power they count on to get the job done.
 
- STIHL ElastoStart™ - The ElastoStart™ starter handle is a feature of STIHL. It is a starting grip with a built-in shock absorber that helps reduce the effort when pulling on the starter cord. The ElastoStart™ starter grip noticeably reduces the sudden peak forces (compression) normally felt during cranking. The forces which occur at the grip after the first compression stroke are smoothed out.
 
- TapAction™ AUTOCUT® Cutting Head - TapAction™ allows users to adjust the line length simply by tapping the cutting head against the ground.
 
- 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°.
