The Stihl MS500i chainsaw is recommended by Masseys as a saw for the professional user. It is the first ever chainsaw with fuel injection technology which gives it the best power-to-weight ratio on the market, and the simplest operation. It has been designed for the harvesting and processing of large timber thanks to its unique lightweight design and outstanding acceleration.

Masseys assemble your chainsaw, PDI it and make sure it is running before you leave the store which will reduce any unwanted down time. Don’t forget, Masseys in Swadlincote, Derbyshire has one of the largest Stihl displays in the UK! Click to see our full range of Stihl chainsaws.

The chainsaw is in our Swadlincote store and we are open 7 days a week.

Features of Stihl MS500i Chainsaw


STIHL Injection (i) – This enables the MS 500i to achieve extremely high performance with both 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.

Best power-to-weight ratio – This is thanks to the new engine technology and lightweight construction. The MS500i is ideal for heavy timber felling, cutting into lengths, and pruning.

Very easy to start, whether starting from cold or warm – The starting process is perfect, with no need for a start position, and easy access to the purger.

STIHL 2-MIX engine – The two-stroke engine with STIHL 2-MIX technology saves up to 20 percent of fuel and reduces emissions by up to 70 percent compared to STIHL 2-stroke engines.

Sensor-controlled fuel metering – The Stihl MS500i has a pressure and internal temperature sensor in its engine. Optimum fuel will be delivered quickly to the engine.

HD2 filter with radial seal – The new HD2 air filter, made from PET material and featuring a radial seal, prevents the intake of fine dust particles and reduces wear.

Decompression valve – Part of the easy starting system. The valve is pressed to reduce compression when starting.


On the chainsaw

STIHL ElastoStart –  As a result there is a smooth pulling of the starter cord.

Side-mounted chain tensioning – Makes it easy to tension the chain safely.

Plunge guide – To assist with plunge cuts. This ensures better directional control and safe use of the machine during plunge cutting.

Tool free fuel caps – Special caps to open and close the tank cap quickly, easily and without tools.

Optimised bumper spikes – To account for the radial contours of trees. This means the saw bites into wood even better when cutting lengths and felling.

STIHL anti-vibration system – Precisely calculated buffer zones minimise the transfer of engine and saw chain vibrations to the front and rear handles.

Captive nuts – As a result you will not risk losing the nuts on the sprocket. – Optimised sprocket cover – ensures outstanding chip removal.

STIHL Ematic oil pump – Allows a higher volume of oil to be delivered. This is especially useful in dusty conditions or when using a long guide bar.
