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.
All Robin 4 cycle engines have a Product Number label similar to the label illustrated below.
The Model / Serial Number Label has a 14
digit alphanumeric string that consists of the
MODEL number (5 digits) and the SERIAL
number (6 digits). Please note the illustra-
tion below:
EH035A∗XXXX
EH035∗-41-040194
Specification No. LabelModel / Serial No. Label
−X X X X X X
MODEL NO. (5 digits) SERIAL NO. (6 digits)
E H 0 3 5 ∗−
The Specification Number Label has a 11
digit alphanumeric string that consists of the
MODEL number (5 digits) and the SPECIFI-
CATION number (6 digits). Please note that
Robin America specifications use the letters
"X" in place of the asterisk symbol. See
example below:
