The two new chainsaw models improve fuel efficiency by up to 20 percent and reduce emissions by as much as half compared to previous models, according to the company.
VIRGINIA BEACH, Va. – Backed with STIHL low-emission engine technology, the MS 311 and MS 391 improve fuel efficiency by up to 20 percent and reduce emissions by up to 50 percent as compared to previous models, meaning longer run times between refueling and lower fuel costs, the company says.
Both models offer a pre-separation air filtration system that requires fewer filter changes, allowing for longer run times between filter maintenance, and an advanced anti-vibration system that reduces vibration, resulting in operator comfort, the company says.
The STIHL MS 311 and MS 391 also feature a toolless fuel and oil cap with retainers, translucent fuel tank, and side access chain tensioner. The platform design concept allows for streamlined parts and maintenance.
