HOW TO READ THE SHOP MANUAL

VOLUMES
00
Shop manuals are issued as a guide to carrying out repairs.
They are divided as follows:
Chassis volume: Issued for every machine model
Engine volume: Issued for each engine series
Electrical volume: Each issued as one to cover all models
Attachment volume: Each issued as one to cover all models
These various volumes are designed to avoid duplication of
information. Therefore to deal with all repairs for any model,
it is necessary that chassis, engine, electrical and attachment
be available.
