With its excellent power-to-weight ratio, this saw is an impressive piece of equipment for pros looking to take on tree felling, bucking or delimbing operations. Thanks to its unique fuel injection system, the MS 500i delivers rapid acceleration. Combining innovative technology with world-class engineering and durable construction, the MS 500i is another great addition to the long line of legendary STIHL chainsaws. Features Simplified Starting Procedure Saves the user time and reduces the chance of flooding the engine when starting. Ease of use A user-friendly tool for a variety of tasks. Sensor-controlled fuel metering Sensor-controlled fuel metering delivers the right amount of fuel. Lightweight sprocket cover with captive bar nuts Lightweight sprocket cover with captive bar nuts 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. Unique bumper spike design Unique bumper spike design ensures pros can expect optimal performance regardless of what species of tree they're cutting. 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. 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%. HD2 Air Filter The HD2 air filter on this unit is washable, providing extremely long filter life and lowering maintenance costs. The large surface area allows for longer run times between cleanings and high performance even while operating in dusty and dry conditions. Overall, the HD2 air filter provides better protection of the engine compared to standard air filters. Fuel and oil caps with retainers The fuel and oil cap retainers keep the caps attached to the unit for added convenience. Quick acceleration Quick acceleration helps deliver excellent cutting performance. Quarter Turn Lock on the Air Filter Shroud The quarter-turn shroud lock provides quick access, so users can quickly and efficiently service the chain saw with minimal down time on the job. 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. 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. High Output Adjustable Oiler When used with STIHL OILOMATIC ® saw chain and STIHL Ematic ™ guide bars, the high output oiler can supply additional lubrication if needed for longer guide bars and/or dry/dusty cutting conditions. Power-to-weight ratio Allows users to get more done by minimizing fatigue. New generation MDG 1 Diagnostic Software Allows dealers to quickly identify where service might be needed.

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! 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.
