Features

Common Features

  • STIHL OILOMATIC® SAW CHAIN: STIHL makes its own saw chain.
  • EMATIC™ BAR: Includes a polymer ramp reservoir which holds bar oil until it can be picked up by passing chain. This can reduce oil usage by up to 50%.
  • BUMPER SPIKES: Help prevent pull-in and provide better control, making cutting easier.
  • SPARK ARRESTER MUFFLER: Large baffles which reduce noise level and contain a screen designed to reduce the emission of sparks.
  • STIHL QUICKSTOP® CHAIN BRAKE SYSTEM: Designed to stop the chain in fractions of a second. Can be manually activated or activated by inertia if the kickback force is sufficient.
  • FRONT HAND GUARD: Designed to reduce the risk of injury.
  • FRONT HANDLE: Designed for a secure grip and ergonomically angled for comfort.
  • PROTECTED SPARK PLUG: Protected, yet easy to change.
  • LARGE STARTING HANDLE: Easy to grip.
  • SMOOTH CLEAN DESIGN: No rough edges to snag on clothing or brush.
  • AIR FILTER COVER: Easy to remove for fast and easy filter cleaning or replacement.
  • MASTER CONTROL LEVER™: A single lever operating the choke, starting throttle lock and on-off switch.
  • REAR HAND GUARD: Reduces the risk of injury as well as provides a wide area for foot placement during starting.
  • HIGH-TECH POLYMER HOUSINGS: Lightweight, withstand greater impact and are corrosion-resistant.
  • TRANSLUCENT FUEL TANK: Allows operator to easily check fuel level before starting work.
  • ANTI-VIBRATION SYSTEM: Helps reduce operator fatigue.
  • ELECTRONIC IGNITION: Provides easier starting and smoother running.
  • REPLACEABLE "IN TANK" FUEL AND OIL FILTERS: Lower cost and are easy to maintain.
  • INBOARD CHAIN BRAKE: Requires less maintenance and makes saw chain sprocket easier to remove.
  • AUTOMATIC BAR AND CHAIN OILER: Lets operator concentrate on cutting, not on bar lubrication.
  • CHAIN CATCHER: Helps reduce the risk of operator contact by a chain if it should break or derail.
  • THROTTLE TRIGGER LOCKOUT: Must be depressed before the trigger can be activated.
  • *NOTE: STIHL chainsaws have many common features. However, all models may not have all features shown here. Consult your Dealer for details.

Model Features

  • 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.
  • BUILT IN THE USA: A majority of STIHL gasoline-powered units sold in the United States are built in the United States from domestic and foreign parts and components.

Standard 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.
  • 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.
