What's; Why Should I Read This Book - Kohler K91 Owner's Manual

What's In This Book?
This publication is designed to familiarize the
reader with basic hydraulics. It starts by defining
common terms and components used with
hydraulics. The components are then put
together to show how they function in a
hydraulic circuit.
Once you are familiar with the basics, the book
will review some of the systems that are used
on Toro
(R)
equipment. A section on problem
solving covers what to do when you encounter a
problem. Test equipment is also reviewed to
ensure you can properly diagnose and repair
hydraulic systems.
For detailed service information on a specific
unit, please refer to the appropriate service and
repair manual.
This publication uses a building block approach.
It is necessary to understand the information in
the front of the book to better understand
information presented later. Review sections
throughout the book include questions which
involve the key concepts presented. If some
questions are difficult to answer, review the
information again before proceeding.
Answers to the review questions are provided
near the end of the book.
