Features:

• MS-Wrap Handle (R)
• Enables the saw to be used in multiple positions for felling or limbing while keeping your hands in the proper positions for control and safety.
• Ematic™ Lubrication System
• When used with STIHL OILOMATIC® saw chain, this system provides optimal lubrication and can reduce bar oil consumption by up to 50%. Ramps in the guide bar help direct oil to where it’s needed most—bar rails, chain links, rivets, and driver holes.
• STIHL ElastoStart™
• This starter handle includes a built-in shock absorber to reduce effort and smooth out peak forces during starting, making cold starts easier and more comfortable.
• HD2 Air Filter
• Washable and long-lasting, the HD2 air filter provides superior filtration, extending run times between cleanings and ensuring high performance even in dusty conditions.
• IntelliCarb™ Compensating Carburetor
• Automatically adjusts the air/fuel mix to maintain optimal RPM as the air filter becomes dirty—ensuring reliable power even in harsh conditions.
• STIHL Quickstop® and Second Chain Braking System (Q)
• The STIHL Quickstop® chain brake helps reduce injury risk during kickback. The second manually activated brake stops the chain within one second when the operator fully releases the rear handle—a safety feature exclusive to STIHL.
• Bumper Spikes
• Provide a firm grip in wood to prevent pull-in and give better control for easier, more efficient cutting.
• Lightweight Sprocket Cover with Captive Bar Nuts
• Securely attached bar nuts make chain maintenance faster and easier, while reducing the risk of losing hardware.
• Adjustable Automatic Oiler
• Customize lubrication for different bar lengths and cutting conditions, optimizing oil use and performance.
• Decompression Valve
• Manually activated to reduce cylinder compression during cranking, making the saw significantly easier to start.
• Side-Access Chain Tensioner
• Allows for quick and convenient chain adjustments with a bar wrench, eliminating the need for front-mounted tensioners.
• Master Control Lever™
• A single lever conveniently operates the choke, starting throttle lock, and on/off switch for intuitive, efficient operation.
• STIHL Anti-Vibration System
• Reduces operator fatigue and improves comfort, especially during prolonged use or when running long guide bars.
• Toolless Fuel and Oil Caps with Retainers
• Easy-open caps eliminate the need for tools—simply lift, twist, and go.
• Throttle Trigger Lockout
• A safety feature that must be depressed before the trigger can be engaged—see it in action!
