Frequently asked questions
What kind of work is the Stihl MS 291 built for?
Stihl describes the MS 291 as a powerful gas chainsaw for harvesting firewood and for work in agriculture, construction and horticulture. Behind that description sits a 55.7 cc engine producing 2.8 kW, or 3.8 hp, enough to keep cutting through repeated firewood-length rounds rather than stall on occasional light garden pruning.
How powerful is the Stihl MS 291's engine?
The Stihl MS 291 runs a 55.7 cc engine rated at 2.8 kW, which Stihl also states as 3.8 hp. That displacement and output put it above light homeowner saws and closer to machines meant for regular firewood cutting, where the engine has to pull a loaded chain through dense trunk wood repeatedly without bogging down.
What bar length does the Stihl MS 291 run?
The Stihl MS 291 is specified with a recommended bar length of 45.7 cm. Paired with its 2.8 kW engine, that reach handles most firewood-sized trunks and general property cutting in a single pass, without the extra weight and reduced control that a longer bar would add to the front of the saw.
How much does the Stihl MS 291 weigh?
The Stihl MS 291 weighs 5.6 kg without bar and chain. Once the 45.7 cm bar, the chain, fuel and chain oil are added, the saw carried to the woodpile is meaningfully heavier than that figure. At 5.6 kg dry it is a two-handed saw for ground-level cutting, not a saw meant for overhead pruning.
What fuel and chain pitch does the Stihl MS 291 need?
The Stihl MS 291 runs on gasoline with no more than 10% ethanol content and turns a 0.325 inch pitch chain. Sticking to that ethanol limit protects the fuel system from the damage higher blends cause, and the 0.325 inch pitch is a mid-size chain commonly stocked for saws in this power class.
