The STIHL MS500i is the first professional petrol chainsaw with injection technology, great all forestry tasks and packed with additional features such as M-Tronic, HD2 filters, economical 2-mix engine. Everything about this chainsaw is designed to be ready when you are no matter the weather and for long cutting sessions.
- Available with a 20-inch or 25-inch bar
- Highly powerful engine performance,
- Under 8 kilos in weight fully fueled,
- Easy to clean.
- Electronically controlled ignition (M-Tronic),
- 2-year warranty (domestic only)
The first chainsaw with fuel injection, THE MS500i C-M HAS A GREATER POWER TO WEIGHT RATIO.
Firstly, the M-Tronic system manages ignition sequences and fuel metering in every single operating mode, so the user can start the machine without worry and it will keep constant power under load.
Secondly, sensors have a cold or warm start recognition, which will take into account the conditions of the environment such as outdoor temperature and air mass and adjust the fuel/air mixture accordingly. This means the user can start and operate the MS 500i in even the coldest environments, with maximum performance being delivered within a few seconds.
Lastly, M-Tronic ensures this Stihl chainsaw is easier to start than other models. Now there is just one start position on the combi-lever, just pull on the starting cord a few times and there is immediate acceleration to speed (in all weathers). With the help of ElastoStart compression shock is reduced, so the starting procedure is less demanding on the user’s arms and joints.
Additionally, when using the MS500i in similar conditions as before, the electronic system will keep the adjustments necessary to ensure optimal performance and the engine starts again.
Why injection engines are better?
Stihl injection technology enables the MS 500i to achieve extremely high performance with extraordinarily low displacement and low weight. The saw uses innovative technology to achieve rapid acceleration from 0 to 100 km/h in an unbelievable 0.25 seconds. The powerful saw is ready to use right away. Sensors measure air pressure and internal and external temperature and pass the information on to the control unit. This can use the identified values to determine the optimum fuel quantity and ignition timing.
Better power-to-weight ratio
Its revolutionary chainsaw engine technology and resulting intelligent lightweight construction result in the best power-to-weight ratio on the market. The optimised design – with lightweight sprocket cover, more compact engine unit, flywheel with a low design height, and a reduced-weight crankshaft adapted to the low weight of the flywheel – makes work significantly more comfortable. The MS 500i is ideal for heavy timber felling, cutting into lengths, and pruning.
Easy to maintain, so your chainsaw will last far longer.
Being a professional petrol-powered chainsaw, some would expect the MS500i to be harder to maintain – but this certainly is not the case.
For example, this professional chainsaw by Stihl has a long life filter that lasts five times longer than previous models. The air-filter system actually removes harsh dirt particles through a pre-separation system before the air flows through the improved HD2 filter, which filters out even the finest of dust particles.
Additionally, the inbuilt compensator controls the carburettor preventing the fuel-air mixture getting richer as the air filter becomes clogged. The correct quantity of fuel is delivered to the carburettor depending on the quantity of air passing through the air filter. This keeps the fuel/air ratio in the combustion mixture constant and hence also the engine power. The filter doesn’t need to be cleaned until an appreciable drop in power occurs
Consequently, this makes the engine last longer, perform for longer without the need to replace the filter as often. And when the time comes to replace the filter cartridge, it’s quick and easy and can be done without tools.
Furthermore, the MS500i has a petrol engine which is highly efficient and will reduce fuel consumption. This is achieved by the 2-mix engine and the advancements of the four overflow channels, which swirl the fuel-air mix before ignition, allowing for optimum combustion and highly efficient performance. The result is lower fuel consumption and high torque across a broad rpm range.
Increased cutting power with a comfortable grip.
Whether you are using the 20″ or 25″ bar and chain, the Stihl MS500i has a fantastic cutting performance. The .325″ pitch of the chain is designed to precise cut the timber at high speed without splinter the wood.
What’s more, when using the Ematic chain lubrication system, it ensures pinpoint lubrication of the saw chain links and guide bar rails. This will provide maximum lubrication, longer wear and less oil consumption than conventional methods of chain lubrication. The Ematic system can reduce bar oil consumption by up to 50%. The new oil pump system allows a higher volume of oil to be delivered. This is especially useful in dusty conditions or when using a long guide bar.
When changing the cutting attachment, you will not risk losing the nuts on the sprocket. The MS500i is one of the first Stihl chainsaws to be equipped with the captive nuts. A great advantage for all users. Additionally, the side tensioner removes the need to have contact with the sharp saws of the chain.
Finally, this pro chainsaw is equipped with an anti-vibration system, to reduce the vibration at the handles. Therefore, the user will benefit from less fatigue over prolonged use of the power tool.
Special components, such as the cylinder with its angled cooling ribs, the compact sprocket cover, the light crankcase, the weight-optimised flywheel and the Rollomatic ES Light rail ensure that the machine is noticeably lighter.
