TOPIC PRESENTATION: Operator's Manual

A. Importance of Operator's Manuals

   1. The operator's manual is an essential part of a tractor or other
       agricultural machinery; always read it completely before operating
       a tractor or other machinery for the first time in order to protect
       yourself as well as the equipment.
   2. The operator's manual lists the manufacturer's recommendations for 
       proper rpm settings, gear selection, operation adjustments, and
       maximum loads. These procedures and specifications for the individual 
       machines should be followed in preference to general rule-of-thumb 
       adjustments which can result in inefficient performance and/or costly 
       damage to engines and components.

   3. The operator's manual outlines specific timetables for routine 
       maintenance checks and services necessary for preventive maintenance.

   4. The operator's manual is the best source of specific safety 
       information about the tractor or machine for which it has been 
       written.

   5. The operator's manual should be supplemented with a service manual
       when repair work beyond preventive maintenance becomes necessary
       and replacement parts must be ordered. Parts catalogs can also
       be helpful.

B. Contents of Operator's Manuals

   1. The table of contents identifies the main sections of the manual
       and the page numbers where they can be found.

   2. The first section of an operator's manual usually deals with safety.

   3. Subsequent sections usually present the following subjects:

       a. Controls and instruments

       b. Engine break-in procedure

       c. Prestarting checklist

       d. Starting and stopping procedures

       e. General operation and adjustment

       f. Preventive maintenance

       g. Troubleshooting charts

C. Service Manuals

   1. Although operator's manuals give some specifications for tune-up and 
       adjustments, service manuals should be used for major tune-ups and 
       repairs.

   2. Service manuals can be obtained from equipment dealers, from 
       manufacturers, or from publishing companies.

   3. Service manuals give the manufacturers' recommended specifications 
       and procedures to be used in servicing particular machines.

   4. The complete service recommendations should be read before beginning 
       any service work.

   5. The recommended procedures should be followed exactly.

   6. The service manual should be referred to each time service is 
       performed; a written manual is a more reliable guide to proper 
       service than memory.

         ACTIVITY:

         1. Use an operator's manual to learn how to operate a 
             tractor or other agricultural machinery; additionally, 
             use the manual to locate grease points.

         2. Use an operator's manual to identify tractor parts 
             numbered on a tractor.

         3. Use an operator's manual or service manual to identify 
             and order a repair or replacement part.
