3 HOW TO USE THIS MANUAL Robin engines are identified by MODEL, SPECIFICATION, and CODE NUMBER. For each model there may be many different versions called specifications. Each specification will be unique in some way. The difference may only be the paint color or it may have a different type of PTO or some other significant difference. In order the identify the correct service part number, it is important to confirm the specification and code numbers for your engine. The specification and code number together are know as the PRODUCT NUMBER. All Robin 4 cycle engines have a Product Number label similar to the label illustrated below. PRODUCT NUMBER LABEL PRODUCT NUMBER LABEL LOCATIONS The Product Number Label has a 15 digit alphanumeric string that consists of the SPECIFICATION (SPEC) number (11 digits) and the CODE number (4 digits). Please note the illustration below: E Y X X X X SPEC NO. (11 digits) CODE NO. (4 digits) PRODUCT NO. (15 digits) '00-04
