STIHL MS 500i is the first chain saw on the worldwide market with electronically controlled fuel injection.
Designed and built exclusively for forestry personnel and tree service professionals, the MS 500i is the first ever chainsaw on the worldwide market with electronically controlled fuel injection. 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 chain saws.
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.
The decompression valve reduces the compression in the combustion chamber during cranking and helps reduce the effort needed to pull the starter rope.
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.
Fuel and oil caps with retainers
The fuel and oil cap retainers keep the caps attached to the unit for added convenience.
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.
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%.
Ease of use
A user friendly tool for a variety of tasks.
HD2 Air Filter
The new HD2 air filter on this unit is washable, providing an 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 downtime on the job.
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
