STIHL E14 & E20 Electric Chainsaw Workshop Service Repair Manual Part # 0455 105 0123 36 Pages This OEM Manual is the REAL DEAL and not a reprint. I recently purchased a huge lot of manuals from a DOT Repair Facility. This manual has been used in a repair shop and may have dirt, grease, fingerprints, writing, and smudging on some pages.
