A good quality, well-featured domestic chainsaw at an affordable price is something of a Holy Grail & Mountfield appear to have found it with this range of machines. The Mountfield MC640 Two-Stroke Petrol Chainsaw features a powerful 2-stroke Mountfield engine with a power output of 1.50kw, & a displacement of 40.1cc, plus a chain bar of 40cm, enough to create logs & firewood on a medium sized domestic property or to fell small saplings & limb or prune. A pump primer means starting is swift & trouble free, with electric ignition & a reliable recoil start. A sprocket nose at the end of the chain bar spins to decrease friction, increase cutting performance & lengthens the working life of the chain. Maintaining the correct tension on your chain is important for safety, & should be check each time you use it. The chain should be snugly fitting to the bar & this is addressed with the featured side chain tensioner. Chain lubrication is equally as vital & this chainsaw features not just auto lubrication, but auto & adjustable lubrication, which is very unusual to find on a chainsaw in this price range. A double acting chain brake is there for safety & to protect the machine from damage during a sudden stop. It can be operated both by inertia
- so a ‘kickback’ would engage the chainbreak
- & by using the lever with your wrist or h&. This model has a low enough weight, combined with great balance, to make it easy & pleasant to handle & use.
