The wrap-handle design of the MS 500i R is intended to specifically meet the needs of forestry personnel and tree service professionals. The revolutionary MS 500i R was the first chainsaw on the worldwide market with a wrap-handle design and electronically controlled fuel injection. An excellent power-to-weight ratio and ergonomic design make this saw a versatile tool for felling, bucking, or delimbing operations in multiple positions. A combination of leading-edge innovation and world-class engineering, the MS 500i R is able to deliver uncompromising performance with rapid acceleration thanks to its unique fuel injection system, making it a nearly unparalleled addition to the growing catalog of legendary STIHL equipment.
MS-Wrap Handle (R) – Saw can be used in multiple positions for felling or limbing with hands in the proper positions.
Sensor-Controlled Fuel Metering – Sensor-controlled fuel metering delivers the right amount of fuel.
Extended Chip Deflector on Sprocket Cover – The deflector helps to route chips, dust, and debris downward and away from the operator.
Quick Acceleration – Quick acceleration helps deliver excellent cutting performance.
New Generation MDG 1 Diagnostic Software – This product’s diagnostic software allows dealers to quickly identify what service might be needed.
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.
Simplified Starting Procedure – Saves the user time and reduces the chance of flooding the engine when starting.
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.
High Power-to-Weight Ratio – This feature allows users to get more done by minimizing fatigue.
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%.
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.
Lightweight Sprocket Cover with Captive Bar Nuts – The sprocket cover is lightweight and the captive bar nuts are held securely in place for efficient saw chain maintenance.
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.
Purge Pump Primer – The purge pump primer feature enables the user to prime the carburetor with fuel, enabling easier starting. The purge pump primer is designed in a way that the operator cannot flood the machine by priming the carburetor too many times. Flooding the engine is still possible if the choke is not removed after the engine turns over.
Unique Bumper Spike Design – Unique bumper spike design ensures pros can expect optimal performance regardless of what species of tree they’re cutting.
Decompression Valve – The decompression valve, also referred to as ‘deco’ or ‘deco valve’, vents compression in the cylinder for easier starting. The decompression valve temporarily reduces the compression in the combustion chamber during cranking and helps reduce the effort needed to pull the starter rope. It is opened manually and closes automatically as soon as the engine fires.
Translucent Fuel Tank – The semi-transparency allows operators to easily check the fuel level before starting work.
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.
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.
Toolless Fuel and Oil Caps with Retainers – Simply lift the lever and twist the caps to remove or tighten. There’s no need to use a tool to tighten or loosen.

Warning & Safety Information:
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.
STIHL recommends the use of green reduced kickback bars and green low kickback chains on all STIHL chainsaws.
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.
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.
