Introduction INTRODUCTION This technical manual
is part of a twin concept of service. FOS - for
reference Technical Manuals - for actual
servlce The two kinds of manuals work as a team
to give you both the general background and
technical details of shop service. rundamentals
of Service (FOS) Manuals cover basic theory of
operation, fundamentals of troubleshooting,
general maintenance, and basis types of failures
and their causes. They are for training new
personnel and for reference by experienced
technicians. Technical Manuals are concise
service guides for specific machines. They are
on-the-job guides containing only the vital
information needed by an experienced service
technician.

• FEATURES OF THIS TECHNICAL MANUAL
• John Deere ILLUSTRUCTION format emphasizing more
  detailed pictures and fewer words.
• Instructions and illustrations grouped together
  in easy-to- use modules.
• Removal and Installation groups preceding some
  repair groups. These groups show how to remove
  and install components from the machine rather
  than from major components. They also show how to
  acquire access to major components of a machine.

This technical manual was planned and written for
you - an experienced service technician. Keep it
in the shop where it is handy. Refer to it when
you need to know correct service ' procedures
or specifications. "/

Using the technical manual as a guide will reduce
error and costly delay. It will also assure you
the best in finished service work.

Safety
Avoid loose clothing that can catch on some
part of the machine. Wear safety glasses while on
the job. Avoid working on equipment with engine
running. If it is necessary to make checks with
engine running, ALWAYS USE TWO PEOPLE -with the
operator, at the controls, able to see person
doing the checking. KEEP HANDS AWAY FROM MOVING
PARTS. DO NOT enter tank unless another person
is present. Always shut off tractor engine and
shift to PARK when leaving tractor. Remove key
when leaving tractor unattended. Al ays have
seeder stationary and on level ground when
raising or lowering outriggers. DO NOT raise or
lower outriggers when moving. When outriggers
are raised and lock-up pins are not in transport
position, never allow anyone where a falling
outrigger could strike them. 8A5

AVOID FIRE HAZARDS Be prepared if an accident or
fire should occur. Know where the first aid kit
and the fire extinguishers are locatedknow how
to use them. Don't smoke while refueling or
handling highly flammable material. Shut off the
engine when refueling. Use care in refueling if
the engine is hot. Dont use open pans of
gasoline or diesel fuel for cleaning parts. Use
good commercial, nonflammable solvents. Provide
adequate ventilation when charging
batteries. Don't check battery charge by placing
metal objects across the posts. Don't allow
sparks or open flame near batteries. Don't smoke
near battery. Never check fuel, battery
electrolyte, or coolant levels with an open
flame. Never use an open flame to look for leaks
anywhere on the equipment. Never use an open
flame as light anywhere on or around the
equipment. When preparing engine for storage,
remember that inhibitor is volatile and therefore
dangerous. Seal and tape openings after adding
the inhibitor. Keep container tightly closed when
not in use.
