    All chain saw service, other than the items listed in the operation and maintenance sections, should be performed by your nearest Homelite service dealer. Do not use in the rain, snow or wet conditions. Always maintain a proper stance.
  • Page 4 IMPORTANT SAFETY INSTRUCTIONS KICKBACK See Figures 1 and 2. WARNING: Kickback may occur when the moving chain contacts an object at the upper portion of the tip of the guide bar or when the wood closes in and pinches the saw chain in the cut. Contact at the upper portion of the tip of the guide bar can cause the chain to dig into the object and stop the chain for an instant.
