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 specifica-

tion 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.

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:
