Heavy-duty professional use chain saw with a second manually activated chain braking system. With the same “must have” features as the MS 441, this heavy-duty professional use chain saw is equipped with STIHL Quickstop® and second chain braking system. Great for felling, limbing and other specialized forestry operations, the MS 441 C-Q STIHL Magnum lowers fuel consumption and emissions, without sacrificing power.
