Stihl MS 500i Professional Chainsaw Features
-
Ease of use
A user-friendly tool for a variety of tasks.
-
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%.
-
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.
-
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.
-
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.
-
Lightweight sprocket cover with captive bar nuts.

-
Quick acceleration
Quick acceleration helps deliver excellent cutting performance.
-
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.
-
Power-to-weight ratio
Allows users to get more done by minimizing fatigue.
-
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.
