Stihl MS391 20 Inch Petrol Chainsaw
Delight in this high-power 64cc chainsaw manufactured for demanding farming jobs or property maintenance, with the MS391 20” Chainsaw from Stihl. With excellent user comfort and cutting performance, the MS391 high torque engine operates over a wide range of speeds, making light work of harvesting wood and gliding through firewood for a cosy night by the fire!
The versatile, top of the range Chainsaw boasts an impressive range of economical and environmentally sound features thanks to the innovatively designed Stihl 2-Mix engine. Cutting harmful emissions by up to 50% and reducing fuel consumption by up to 20%, Stihl’s 2-Mix technology is the energy-efficient option compared to the previous model without a 2-Mix engine.
Delivering improved cutting performance whilst being compact and lightweight, this easy to use Chainsaw is fitted with Stihl’s anti-vibration system for maximum comfort and control, reducing hand fatigue during extended sawing periods. Both domestic users and farmers will value the simple setup and operation of the MS391, benefiting from a side-mounted chain tensioner and single angle-lever master control which will revolutionise tiresome gardening chores for the better!
Stihl manufacturers ensure their high-quality Chainsaws are crafted with durability and reliability in mind. Fitted with a pre-separation air filtration system, the long-lasting filter life of the high torque MS391 is protected as it naturally becomes clogged thanks to the carburettor’s compensator. Controlling the fuel-air mixture, these ergonomically designed measures maintain the engine power for consistent high-powered performance. Complete with automatic Stihl Ematic chain lubrication, the innovative MS391 regulates oil bar consumption for optimum durable wear of the chain.
