MS 500i R

First STIHL chainsaw with electronically controlled fuel injection provides consistent power under changing conditions and a wrap handle.

The MS 500i R —the first chainsaw on the worldwide market with a wrap-handle design and electronically controlled fuel injection —is designed and built specifically to meet the needs of forestry personnel and tree service professionals. An excellent power-to-weight ratio and wrap-handle 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.

Model Features

  • Wrap Handle (R)
    Saw can be used in multiple positions for felling or limbing with hands in the proper positions.
  • 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.
  • 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.
  • 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.
  • 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%.
  • 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.
  • 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.
  • 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.
  • 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.
  • Power-to-weight ratio
    Allows users to get more done by minimizing fatigue.
  • 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
  • Unique bumper spike design
    Unique bumper spike design ensures pros can expect optimal performance regardless of what species of tree they're cutting.
  • Quick acceleration
    Quick acceleration helps deliver excellent cutting performance.
  • Ease of use
    A user-friendly tool for a variety of tasks.
  • New generation MDG 1 Diagnostic Software
    Allows dealers to quickly identify where service might be needed. Diagnostic software
  • Simplified Starting Procedure
    Saves the user time and reduces the chance of flooding the engine when starting.
  • Fuel and oil caps with retainers
    The fuel and oil cap retainers keep the caps attached to the unit for added convenience.
  • Wrap handle version (R) with extended chip deflector on sprocket cover
    Features a wrap handle with extended chip deflector on sprocket cover

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.
