Can I be directed, please, to a Users manual for this pre-1980 McCulloch 12 inch electric chainsaw. The identification plate on it also refers minorly to Black & Decker ( Canadian manufacturer which may have manufactured by licence or distributed it ?. ) IF no specific manual, what McCulloch electric chainsaw manual would be closest relevance. Thanks for checking. Safety is very big concern. Bob Driscoll (613) 267 -2891 March 25 2015
