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:
X X X X
SPEC NO. (11 digits) CODE NO. (4 digits)
PRODUCT NO. (15 digits)
E X 1 3 0
