3. INTRODUCTION
This manual illustrates and identifies maintenance parts for the
Model 2500 Loader, to enable you to determine the part num~er
and name assigned to the part you wish to order. Ordering
by proper part number and name will help ensure the receipt
of the proper part the first time without time-consuming exchanges
of correspondence or other annoying delays.
An index is provided in the front of this manual to help you
determine which illustration contains the part you want to order.
Determine the basic system or assembly in which the part is
used, and find this system or assembly in the Index. It will
reference the pages which illustrate and list the part.
This manual contains the latest information available at the time
of printing. However, at the discretion of Trojan Industries Inc.
its contents are subject to change without notice. This reservation
is in keeping with the Company's policy of constant progressive
improvement and refinement of all our products. As a result of
such policy, certain changes may be made from time to time which
will not be covered in this manual.
Because we are constantly upgrading our equipment, it is necessary
that the SERIAL NUMBER of your machine accompany every repair-
parts order. To assure the receipt of the proper part, it is
essential that the following information be included with your
parts order:
MACHINE MODEL NUMBER
MACHINE SERIAL NUMBER
PART NUMBER OF THE DESIRED PART
PART NAME OF THE DESIRED PART
QUANTITY OF ITEM WANTED
NAME AND ADDRESS TO WHICH PART SHOULD BE SENT
USE ONLY PARTS WHICH ARE AUTHORIZED BY TROJAN INDUSTRIES, INC. TO
ENSURE THAT ORIGINAL DEPENDABILITY AND PERFORMANCE WILL BE MAINTAINED.
Certain abbreviations are used in the parts list to call your attention
to specific situations. These abbreviations are explained as follows:
AIR - As Required: No specific quantity can be assigned
to the part since the number used varies from machine
to machine.
