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.
Anti-Vibration System
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.
Bike Handle
The electronic ignition provides reliable starting and because it is fully enclosed, it is protected from moisture and debris for longer service life.
Electronic Ignition Module
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.
IntelliCarb™ Compensating Carburetor
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.
Multi-Function Control Handle
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.
Purge Pump Primer
The STIHL Inc. “Caring for Nature” seal identifies its powered products that are more environmentally conscious, producing zero or low exhaust emissions. STIHL Inc. defines “low exhaust emissions” as being cleaner than EPA and/or CARB exhaust emission standards.
Reduced-Emission Engine Technology—Caring for Nature
Built to make tough work more comfortable, the FS 561 C-EM features a rugged professional design with a four-point anti-vibration system that allows for optimal control and reduced fatigue.
Rugged Professional Design
The STIHL Easy2Start™ system makes starting STIHL outdoor power tools almost effortless, eliminating the need for a strong pull of the starting cord. This advanced starting system is designed to make starting STIHL products easier. The specific system may vary by model, but in each case, a quick pull overcomes the engine’s compression to minimize the strength and effort required to start. Available on selected products.
STIHL Easy2Start™
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.
STIHL ElastoStart™
The STIHL M-Tronic™ system intelligently manages the operating performance of the engine. Equipment performance can be affected by a dirty air filter, changes in elevation or poor fuel quality. The STIHL M-Tronic™ system compensates for these factors by eliminating the low and high-speed carburetor adjustment screws and electronically monitoring the engine and digitally controlling the fuel/air mixture. This new technology also provides a simplified warm start procedure.
STIHL M-Tronic™ System
To get started, users simply pump the fuel primer, set the choke, and pull the starter cord. The built-in stop switch allows the user to turn off the engine with a simple press of the button. When the engine is off, the throttle lock automatically returns to the "start" setting. The tool will be ready to start again when the user is ready to get back to work.
Simplified Starting Procedure
This safety feature must be depressed before the trigger can be activated.
Throttle Trigger Interlock
The central wing nut enables easy adjustment without the use of tools. For transportation and space-saving storage, the handle can be rotated 90°.
Tool-Free Handle Adjustment
This product is built with the innovative STIHL FS Advanced Handle Grip for ergonomic operation with multiple grip options for reduced operator fatigue and improved comfort.
