Arrangement and Use of this Manual
Clark arranges parts and service procedures by standard-
ized Groups. In this manual, Groups are similar to “chap-
ters.” Groups are listed in the table of contents on the next
page.
You can quickly locate a specific point in the manual by
using the headers and footers that appear on the pages. The
following illustration points out these areas.
Each Group begins with a table of contents that shows the
Sections contained within the Group. Lengthy Sections
also begin with a table of contents showing the topics
contained within the Section.
Each Group and Section has an identifying name and
number, or “ID.”
Each page also has a unique ID. The page ID consists of
three numbers separated by hyphens. The three numbers
represent the Group number, the Section number, and the
page number. For example, “00-1-2” on the lower comer
of the page indicates Group 00, Section 1, Page 2.
This manual is intended for the use of trained service
personnel. Please read Group SA, “Safe Maintenance,”
and the Operator’s Manual before working on or operat-
ing the truck.
