These heavy-duty steel springs are resistant to fuel, temperature variation and UV light. * Air Injection. Centrifugal air cleaning system for longer intervals between filter cleanings, smoother operation and reduced wear. * Smooth underside, rounded starter cover and well-protected controls make the saw easy to handle, reduce the risk of getting caught in tree branches and make transportation easier.
