Features

• WINTER / SUMMER SHUTTER: The Winter/Summer Shutter allows the carburetor to operate at optimum temperature year-round and helps to prevent carburetor icing when working below 50°F (10°C).
• DECOMPRESSION VALVE: The decompression valve, also referred to as 'deco' or 'deco valve', vents compression in the cylinder for easier starting. The decompression valve temporarily reduces the compression in the combustion chamber during cranking and helps reduce the effort needed to pull the starter rope. It is opened manually and closes automatically as soon as the engine fires.
• STIHL ELASTOSTART™: The ElastoStart™ starter handle is an exclusive 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.
• PRE-SEPARATION AIR FILTRATION SYSTEM: This time-saving technology boosts the efficiency of the engine’s filter system, doubling the time between air filter cleanings. Air drawn into the engine is first separated via centrifugal force, ejecting the heavier dirt particles before being routed to the air filter. This pre-separation means less dirt to be captured by the air filter, resulting in less frequent cleaning and maintenance.
• SIDE-ACCESS CHAIN TENSIONER: The side-access chain tensioner makes it much more convenient for the user to adjust the saw chain with a bar wrench as opposed to the typical location of the guide bar adjustment screw.
• 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.
• 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.
• 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.
• STIHL QUICKSTOP®: STIHL chainsaws are equipped with a chain stopping system designed to reduce the risk of injury in certain kickback situations. It is called a STIHL Quickstop® chain brake. The STIHL Quickstop® chain brake is designed to stop the rotation of the chain if activated by the operator’s hand or by inertia if the saw kicks back with sufficient force. In some working positions, the STIHL Quickstop® chain brake can be activated by inertia, stopping the chain within fractions of a second.
• EMATIC™ LUBRICATION SYSTEM: The Ematic™ guide bar, when used with STIHL OILOMATIC® saw chain, will provide proper lubrication and less oil consumption than conventional methods. The system works because two ramps, strategically placed in the guide bar rail, help contain the flow of oil and direct all lubrication to the sliding faces of the bar and chain links as well as the rivets and driver holes, which in turn can reduce bar oil consumption up to 50%.
• PROFESSIONAL POWER, RUGGED DEPENDABILITY, AND A STANDARD ADJUSTABLE CARBURETOR: The simple, non-electronic design of its proven carburetor delivers professional power and rugged dependability while allowing for limited adjustments to be made in the field.
• HD2 AIR FILTER: The HD2 air filter on this unit is washable, providing extremely long filter life and lowering maintenance costs. The large surface area allows for longer run times between cleanings and high performance even while operating in dusty and dry conditions. Overall, the HD2 air filter provides better protection of the engine compared to standard air filters.
• HIGH OUTPUT ADJUSTABLE OILER: When used with STIHL OILOMATIC ® saw chain and STIHL Ematic ™ guide bars, the high output oiler can supply additional lubrication if needed for longer guide bars and/or dry/dusty cutting conditions.
• POWER-TO-WEIGHT RATIO: Allows users to get more done by minimizing fatigue.
• LIGHTWEIGHT SPROCKET COVER WITH CAPTIVE BAR NUTS: Lightweight sprocket cover with captive bar nuts.
• UNIQUE BUMPER SPIKE DESIGN: Unique bumper spike design ensures pros can expect optimal performance regardless of what species of tree they're cutting.
• 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.
