  • STIHL Quickstop® Plus (Q) - an additional chain braking feature

  • STIHL Electric Brushless Motor
    Lightweight and compact, STIHL electric motors require minimal maintenance and feature low noise levels and reduced vibration.
  • Coast-down Brake
    A controlled braking device (Q) to stop the rotating chain when the trigger is released.
  • 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.

  • Rubberized Soft Touch Handle 
    Soft rubber texture is both easy to grip and makes the product comfortable to hold for extended periods.  
  • 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%.
  • 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.
  • Lightweight Portability
    Great for maneuverability and extended use.

Important Information

WARNING! 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 (Q) 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 CORDED ELECTRIC AND BATTERY CHAINSAW USERS! The fibers may not stop the sprocket on most corded electric chainsaws and some battery-powered chainsaws because of the constant high torque. However, to reduce the severity of injury from accidental contact with the chain, STIHL recommends that leg protection be worn when operating these types of chainsaws.

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.

Rated 4 out of 5 by from excellent alternative to pull-start gas power excellent alternative to pull-start gas power: Ease of maintenance and just as much cutting ability when up against any 12-14 in arm. And no worry about lugging a gas can and refueling.

Rated 5 out of 5 by from Exactly the saw that I needed for my situation. I recently had surgery. I had someone fell 3 trees for me and needed to purchase a saw to remove branches. I couldn't pull a conventional gas powered chainsaw fearing that I might pull stitches from the surgery. So I looked at the battery powered chainsaws and decided on this model. It only took about 1-1/2 hours to charge. I was impressed with the size of branches that I was able to cut. Also the run time for the battery was better than I expected. It was as simple as pulling the trigger and sawing. No yanking to start. I would recommend this saw to anyone interested in an easy to use saw for clean up applications. And a bonus of no gas or oil to purchase.

Rated 5 out of 5 by from Great for doing the cutting I need around the house Used this saw to take down my split rail fence and it was a piece of cake. Removes small bushes and trees with ease. Battery life is OK for what I am doing may be short if you are doing a big project.

Rated 5 out of 5 by from What an AWESOME Little Saw I love Stihl products but I wanted to try a battery operated saw to carry on my Zero Turn mower. I used to carry a battery operated reciprocating saw, but I figured a Stihl chainsaw would be better. I bought an extra battery, charged them both up and cut down a small ash tree about 6 inches in diameter. I cut it up with no problem. It was no MS 361, but it was a great little saw and it cut a bunch more before the battery finally wore down. I carry it with me a lot because it is so handy. It is not for cutting down big trees, but it sure is great for trimming and cutting up small brush.

Rated 4 out of 5 by from Great for light/medium duty work I had to sell my gas powered medium duty Stihl chainsaw because of a shoulder injury. While this one is less powerful, it still cuts what I need and it doesn't hurt my shoulder

Rated 5 out of 5 by from A wise choice! Couldn’t have done better! I needed a small saw for small jobs and for camping trips. I always hated carrying a gas saw in my Suburban as well as the fuel for it on camping trips. This saw is the perfect solution to my needs and has more power than I expected it to. Handles lots of small to medium jobs here and the battery lasts a long time and charges back up really quickly. I feel I made a wise purchase.
