Description
Overview:
The Chain Sprocket Cover is a genuine Stihl replacement part for pole pruners. It shields the drive sprocket and surrounding mechanism from impacts and debris, helping the chain and guide bar run smoothly and safely. Moulded from impact‐resistant polymer for strength with low weight, it is designed for regular outdoor use and easy handling. Engineered to fit selected Stihl pole pruners such as the HT105 and HT135, the cover sits flush over the bar mount and secures using the machine's standard fixings. Using the correct cover supports safe operation, reliable chain retention and effective lubrication around the sprocket hub.
