This curriculum is designed to supplement the Comprehensive Small Engine Repair guide by covering in detail all aspects of chain saw repair. The publication contains materials for both teacher and student and is written in terms of student performance using measurable objectives. The course includes six units. Each unit contains some or all of the basic components of a unit of instruction: performance objectives, suggested activities for teacher and students, information sheets, assignment sheets, job sheets, transparency masters, tests, and answers to the tests. Units are liberally illustrated and are planned for more than one lesson or class period of instruction. Information for the teacher includes an instructional/task analysis of chain saw repair, and a list of tools needed. Topics covered by the six units are the following: chains, chain sharpening, chain link replacement, bars, chain oilers, and chain saw drives. (KC)
