HOW TO USE THIS MANUAL

Robin engines are identifi ed by MODEL, SPECIFICATION, and CODE NUMBER. For each
model there may be many different versions called specifi cations. Each specifi cation 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 signifi cant difference.

In order the identify the correct service part number, it is important to confi rm the specifi ca-
tion and code numbers for your engine. The specifi cation 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:

E H 0 3 5

SPEC NO. (11 digits) CODE NO. (4 digits)

PRODUCT NO. (15 digits)

(i.e..:Electrical Device Group).

3. REF. No . The Reference number identifi es the part illustration with the corresponding part number in the
part list.

4. SUBASSEMBLY SUBASSEMBLY parts of part assembly are listed below the assembly part. The subassembly
part reference number is indicated by the number led by "-" such as "-1", "-2".

5. PART NUMBER It is the number assigned for sales unit. Use the PART No. when making an order.

6. DESCRIPTION It is designation of the part.
