Stihl MS 441

2-Stroke

The Stihl MS 441 is a 70.7cc <!-- verify: stihlusa.com --> 2-stroke professional chainsaw for high-production logging, timber framing, and heavy land clearing, accepting 20" to 28" guide bars. It runs a Walbro carburetor <!-- verify: stihlusa.com --> and features a large-volume air filter and side-access chain tensioner. Under production logging conditions, fuel system components require attention every 50–100 hours. A sharp chain at this power level is both a safety requirement and an efficiency necessity — dull chains cause excessive fuel consumption and accelerated bar wear.
