Features
- 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%.
- STIHL Electric Motor -
  Lightweight and compact, STIHL electric motors require minimal maintenance and feature low noise levels and reduced vibration.
- Quick Chain Adjuster (QCA) (B) -
  The Quick Chain Adjuster (QCA) (B) allows the user to adjust the tension of the chain without the use of tools. This allows for easy chain adjustment.
- Translucent Bar and Chain Oil Tank -
  The translucent bar and chain oil tank makes it easy for users to check oil levels at a glance.
- Lightweight Portability -
  This product is lightweight for easy portability, great maneuverability, and extended use.
- Rubberized Soft-Touch Handle -
  Soft rubber texture is both easy to grip and makes the product comfortable to hold for extended periods.
- Variable-Speed Trigger -
  The variable-speed trigger allows precise control for each task.
- Throttle Trigger Interlock -
  This safety feature must be depressed before the trigger can be activated.
- 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.
- Made in America -
  A majority of STIHL products sold in America are made in America of U.S. and global materials.

IMPORTANT SAFETY INFORMATION The occurrence called “kickback” can cause serious or fatal injury. Always read the instruction manual carefully before using your saw. STIHL uses a green and yellow color-coding system to help you select a powerhead, bar and chain combination that complies with the kickback requirements of ANSI Standard B175.1 (gasoline-powered saws) and §30 of UL 1662/ ANSI Standard B175.1 (electric chainsaws). Ask your STIHL dealer about safe operating procedures and the advantages of the STIHL Quickstop® chain brake, STIHL Quickstop® Plus additional chain braking feature, STIHL reduced kickback bars and STIHL low-kickback saw chains.

STIHL recommends the use of green reduced kickback bars and green low kickback chains on all STIHL chainsaws.
* The actual listed guide bar length can vary from the effective cutting length based on which powerhead it is installed on.
WARNING FOR ELECTRIC CHAINSAW USERS!
The fibers will not stop the sprocket on most electric chainsaws because of their constant high torque.

WARNING FOR CORDED-ELECTRIC USERS! STIHL recommends that leg protection be worn when operating corded electric chainsaws. However, the fibers may not stop the sprocket on most corded electric chainsaws because of the constant high torque.
WARNING! Improper use of any power tool may cause serious or fatal injury. Read, understand, and follow carefully the operating and safety instructions in your instruction manual before using such products.

STIHL products sold through U.S. STIHL Dealers are for distribution in the United States only.
