Introduction
The information included in this Service Manual has been assembled to give the mechanic or service representative the information necessary to keep the 80 in everyday operation. General information is inducted on the main operating parts of the CRUZ-AIR, with specific repair and troubleshooting information provided only for those aspects of the machine that may be damaged or require maintenance under normal usage.
