The STIHL ROLLOMATIC® E Mini Light is a general-grade laminated guide bar made of high-grade steel. Two metal plates are electrically welded together to provide stability. To reduce weight, it is completely hollowed out after being welded and is filled with fiber-reinforced polymide. The 14” bar is 25% lighter than a comparable conventional guide bar. This bar has excellent rigidity for efficient cutting and better balance during limbing operations and is designed for use with PMM3 saw chain. A sprocket is incorporated in the nose of the bar that carries the saw chain from the top to the bottom of the bar. This not only reduces wear, but also enables the bar nose to be made considerably narrower. This type of construction is an advantage where extensive use is made of the bar nose (i.e. limbing and boring). All STIHL ROLLOMATIC® bars designed with a narrow nose help reduce kickback tendencies. And the star-shaped sprocket can be replaced several times before the whole bar is due for replacement, increasing the bar’s service life. Applications: This bar is primarily intended for use by arborists. STIHL recommends using low-kickback, green-labeled chain and green-labeled reduced-kickback bars on all powerheads. Note: The actual listed guide bar length can vary from the effective cutting length depending upon which powerhead it is installed.
