Features
Anti-Vibration System
STIHL has developed 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.
Bumper Spikes
These spikes prevent pull-in and provide better control, making cutting easier.
High-Tech Polymer Housings
Housings are lightweight, withstand greater impact, and are corrosion-resistant.
IntelliCarb™ Compensating Carburetor
The IntelliCarb™ Compensating Carburetor is designed to automatically adjust the air/fuel ratio when the air filter becomes restricted or partially clogged and maintains the engine’s correct RPM. IntelliCarb™ uses air from the clean side of the air filter to control the diaphragm and flow of fuel. As the air filter becomes dirty and less air is available for the carburetor, the IntelliCarb™ system adjusts the fuel flow to compensate for the decrease in air flow. This is in contrast to typical carburetors that utilize this air from the “dirty” side of the air box.
Made in America
A majority of STIHL products sold in America are made in America of U.S. and global materials.
Master Control Lever™
The Master Control Lever™ is an easy to use single lever, operating the choke, starting throttle lock, and on-off switch. The operator must pull the throttle trigger before moving the Master Control Lever™ to the choke position.
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. STIHL Inc. defines “low exhaust emissions” as being cleaner than EPA and/or CARB exhaust emission standards.
Throttle Trigger Lockout
This safety feature must be depressed before the trigger can be activated.
Toolless Fuel and Oil Caps with Retainers
Simply lift the lever and twist the caps to remove or tighten. There’s no need to use a tool to tighten or loosen.
