John Deere 3025E, 3032E, 3036E, 3038E Manual

(S.N HJ100000 – KL900000)

The technical manual is divided into two parts: maintenance manual and an operational principle and test manual. maintenance manual introduces how to repair machine parts. Operational principles and test manuals help you quickly handle common faults.

In this manual, chapters are classified according to components that require maintenance or checks. At the beginning of each chapter, all relevant basic tools and repair equipment are listed first, then followed by working materials, repair parts, technical specifications, wear tolerances and torque values.

A technical manual is a concise guide for a specific machine. It helps you carry out field work and contains only critical information required for diagnosis, analysis, testing and maintenance. Basic maintenance information is provided by other means, such as basic operational principles, troubleshooting basic knowledge, regular maintenance and basic fault types and their causes.
