Product Description

The MS 500i is a powerful and innovative thermal chainsaw designed specifically for forestry professionals. Its light weight and high acceleration make it ideal for felling and cutting large timber. The felling claws are optimized for increased efficiency.

Thanks to STIHL injection technology, the MS 500i achieves high performance despite its reduced displacement and low weight. Featuring innovative technology, this chainsaw accelerates from 0 to 100 km/h in just 0.25 seconds, making it ready for use immediately. Sensors measure air pressure as well as internal and external temperatures and transmit this information to the control unit to optimize performance.

The stratified-scavenged engine reduces emissions harmful to humans and the environment, making it an ecological choice while also reducing fuel consumption by 20 percent. The HD2 filter provides superior filtration performance, while the fastening nut on the sprocket cover and tool-free filter cover simplify maintenance.

The chain saw is equipped with a high-performance oil pump with adjustable flow, which allows for high flow and ensures optimal chain lubrication. The fuel tank cap is designed to be opened and closed without tools for easy and safe refueling.

Equipment and features:

Steele Injection (i):

Stihl injection technology enables the MS 500i to achieve extremely high performance with extremely low displacement and extremely light weight. The chainsaw features innovative technology that enables rapid acceleration from 0 to 100 km/h in just 0.25 seconds. It can be used immediately. Sensors measure air pressure and internal and external temperatures and transmit the information to the control unit.

Layered scan engine:

At the air intake, a layer of pure air without fuel is inserted between the gases burned in the combustion chamber and the fresh mixture from the lower engine. The buffer reduces the loss of fuel mixture during cleaning, thereby reducing harmful effects on humans and the environment. The engine is environmentally friendly and reduces energy consumption by 20%.

Stihl ElastoStart System:

Elastostart consists of a shock absorber located between the rope and the starting handle. It absorbs the shock caused by compression at startup. Therefore, starting the engine is more flexible and requires less effort. The Stihl element provides comfort and safety.

Very easy to start, even cold:

The startup process is perfect, no need to start position, easy to enter the trap.

Sensor controlled fuel dosage:

In addition to external temperature sensors, the engine of the MS 500i also has internal pressure and temperature sensors. It measures ambient pressure at start-up and checks engine temperature and crankcase pressure during operation. The voltage generator provides the required speed information. The control unit processes these values, which means that the system adapts to the conditions of use. The fuel is then metered to optimal levels, resulting in perfect operating characteristics quickly.

Automatic return to pressure reducer:

The decompression reducer reduces engine compression at startup. So the launcher requires less work. Getting started will be easier and more comfortable. The pressure reducer is a valve located on top of the cylinder. When opened at startup, it relieves some of the pressure in the cylinder. From the first combustion, it automatically switches off, allowing the engine to develop its full power.

Best power/weight ratio:

Its revolutionary motor technology and lightweight construction provide the best power-to-weight ratio on the market. Optimized design - lightweight gear cover, more compact engine unit, low design height of the flywheel and a lightweight crankshaft matched to the lightweight flywheel - make working even more comfortable. The MS 500i is ideal for felling heavy timber, cutting to length and trimming.

HD2 filter with radial seal:

The new HD2 air filter is made of PET material and has a radial seal to prevent the entry of fine dust particles. Hermetic seal extends engine life and reduces wear.

Anti-vibration system:

To reduce vibration in the handle, STIHL has developed a very effective anti-vibration (AV) system. The motor and cutting device are completely suspended from the handle by means of springs or elastomer buffers or by a combination of these two components. The result is great working comfort and reduced risk of poor blood circulation in the hands and arms.

Side chain tensioner:

Side chain tensioners are located on the side of the engine to avoid any contact with the chain or claws when tensioning the chain. Therefore, the operation is very safe and very easy to perform.

The Ematic features a new oil pump system:

New oil pump system releases more oil. This is particularly useful in dusty conditions or when using large rails.

Crimp guide nut:

The guide nut is crimped into the chain case. Therefore, there is no longer a risk of losing the nut when changing the chain or maintaining the guide rail.

1/4 turn fuel tank cap:

To make filling the tank simple, Steele developed a unique tool-free opening and closing system. The filling action is completed quickly and safely, as this concept guarantees a perfect seal.

Diving Guide:

Markings were added to the fan housing to facilitate plunge cutting. This ensures better directional control and safe operation of the machine during plunge cuts.

Optimized sprocket cover:

The flatter, narrower sprocket cover with integrated slide reduces effort when cutting and ensures excellent chip evacuation.

Claw teeth optimization:

The new design of the claws has been adapted to take into account the radial contour of the shaft. It allows the chainsaw to bite into wood more efficiently during various cutting operations.
