Description:

The MSA 300 C-O sets the benchmark in performance as the most powerful battery chainsaw in the STIHL lineup. Certified by the American Green Zone Alliance (AGZA), this battery saw offers a host of features to maximize performance and deliver optimal user comfort. Its lightweight design rubberized soft-touch handle, and anti-vibration technology minimize fatigue. A truly professional-grade battery chainsaw, the MSA 300 C-O also features a lightweight magnesium motor housing that provides added durability to this powerful chainsaw. The electronic operating system, captive bar nut and side-access chain tensioner simplify maintenance. And the fleece air filter, mechanical and electronic chain brake, and oil sensor round out the features of this power-packed saw.

Features:

• Electronic Operating System – Located by the handle of the saw, the electronic operating system allows the operator to easily see how the saw is running
• 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.
• 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.
• IPX4 Rating – This tool has IPX4-rated weather-resistant construction and has been designed and tested for adverse weather conditions.
• 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.
• Magnesium Motor Housing – The magnesium motor housing provides added durability to this powerful chainsaw.
• AGZA Certified – Meets the low-emission standards established by the American Green Zone Alliance.
• 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.
• 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. 
• 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.
• Throttle Trigger Interlock – This safety feature must be depressed before the trigger can be activated.
• 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.
