This is a service manual

Here's how it compares to the other manual types.

This manual

Service manual

Factory repair procedures and technical information such as specifications, troubleshooting, and wiring and hydraulic diagrams, for the models and systems the manual covers. See What's inside for its topics.

Operator's manual

Safe operation, controls, maintenance schedules, lubrication points, inspections, and basic checks. Repair procedures are in the service manual.

Parts manual

Illustrated diagrams with factory part numbers for identifying components and ordering parts. Repair procedures are in the service manual.

Engine service manuals are sometimes sold separately, since certain machine models were offered with more than one engine option.

What it's used for

Factory manual for in-house farm and construction shop use. Straightforward, complete, and easy to follow. It contains the OEM information dealership service departments and parts counters use to diagnose problems, identify components, and perform maintenance or repairs correctly.

Service shops and owner/operators who repair their own equipment

Identifying correct parts and seeing how assemblies come apart and go back together

Keeping equipment running with less downtime
