Important Information
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.
Note: STIHL recommends use of fuel with no more than 10% Ethanol content. Using fuel with greater than 10% Ethanol content may cause damage to your equipment and may void your STIHL warranty.
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.

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%. -
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. -
Decompression Valve
The decompression valve reduces the compression in the combustion chamber during cranking and helps reduce the effort needed to pull the starter rope. -
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. -
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. -
Fuel and oil caps with retainers
The fuel and oil cap retainers keep the caps attached to the unit for added convenience.
