Stihl MS 500i 25 Inch Petrol Chainsaw
Experience cutting-edge performance delivered by cutting-edge technology with the pioneering MS 500i 25 Inch Petrol Chainsaw from Stihl: the world’s first chainsaw complete with Stihl Injection Technology. Machined to leave even seasoned professionals impressed, the greatest power-to-weight ratio Petrol Chainsaw on the market provides elite level power and simple manoeuvrability, pushing the boundaries yet again with outstandingly low displacement and rapid acceleration. This preeminent piece of machinery is ideal for forestry and arboriculture environments, designed to deliver excellent cutting performance when harvesting and processing large timber.
Innovative electrically controlled fuel injection technology makes this powerful Chainsaw ready to use immediately, with no need for a start position, accelerating from 0 to 100km/h in a record 0.25 seconds. Uniquely compact and lightweight in structure, the MS 500i will support you during long working days in the forest; a reduced-weight crank shaft specially tailored to the low design height of the flywheel is guaranteed to make light, comfortable work of heavy timber felling and pruning.
The brand new 2-Mix engine incorporates a 1-in-4 technology, boasting a highly functional and economical 5kW of power whilst cutting harmful emissions by up to 50% and curtailing fuel consumption by up to 20%. Stihl’s 2-Mix technology is the energy-efficient and economical Chainsaw option compared to 2-stroke Mix engines of the same power output.
Stihl manufacturers ensure their highly functional Chainsaws are crafted with durability and reliability in mind. The MS 500i forestry saw is no different, displaying a range of innovative technological features such as the HD2 filter, new bumper spikes, captive nuts on the sprocket cover for efficient chain change and a controlled-delivery oil pump, resulting in an overall robust piece of machinery. Complete with automatic Stihl Ematic chain lubrication and tool-free cap, the outstanding MS500i regulates oil bar consumption for optimum durable wear of the chain and easy filling with fuels and lubricants.
