• IPX4 Rating - This tool is IPX4-rated for weather-resistant construction and has been designed and tested for splash-water protection.
• 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%.
• Brushless Motor - The advanced brushless motor virtually eliminates maintenance while supplying the power and performance you expect from STIHL.
• Magnesium Motor Housing - The magnesium motor housing provides added durability to this powerful chainsaw.
• Captive Bar Nut - The captive bar nut is held securely in place, which eliminates the risk of dropping or losing the bar nut during saw chain maintenance.
• Variable-Speed Trigger - The variable-speed trigger allows precise control for each task.
• Low Oil Sensor - The low oil sensor allows the operator to see when the oil is low so they can keep the bar and chain properly lubricated.
• Toolless and 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.
• 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.
• 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.
• 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.
• 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.
• 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.

STIHL recommends the #3670 (71 PM3 72) OILOMATIC® saw chain and 14" 3005 000 4809 STIHL ROLLOMATIC® E guide bar combination. The actual listed guide bar length can vary from the effective cutting length based on which powerhead it is installed on.
