Maintenance The 70-90 and 80-90 tractors were
designed with the owner in mind and an effort has
been made to simplify maintenance. The purpose of
this handbook is to familiarise the ope- rator
with the operation and regular servicing of the
tractor. Remember that the time spent on
maintenance ex- tends the life of your
tractor. Pay particular attention to the
instructions covering fuel filtering, air cleaner
maintenance and lubrication remember that badly
filtered fuel results in injection sy- stem
deterioration and irregualr air cleaner
maintenan- ce leads to premature engine wear, and
reckon that a tractor oil change every 200 hours
is equivalent to a truck oil change every 8,000
to 9,000 km.
Spare Parts

• Use genuine FIATAGRI parts only. Failure to do
  this will
• Cost you more.
• Not result in complete satisfaction.
• Seriously risk improper functioning of the
  tractor. Original spares are sold by the FIATAGRI
  Sales and Serv- ice Organziation.
• In all orders be sure to quote (see page 7)
• Tractor Model and Frame Number.
• Engine Type and Number.
• The Part No. of the spare needed (listed in the

• If the tractor is to be stored for an extended
  period carry out opera- tions described below.
  See also dis- tributor-type injection pump
  instruc- tions on page 52.
• Protect the engine as follows
• For periods of storage of up to one month no
  precautions are needed provided not more than
  100 hours have elapsed since the last engine oil
  change, otherwise see be- low.
• For storage periods in excess of one month, drain
  engine oil with a warm engine, fill the sump with
  oliof- iat AMBRA SUPER oil and run the engine at
  part throttle for a few mi- nutes.
• Remove air cleaner outer car- tridge and clean
  as directed in Servi- cing Chart.
• Do not drain the engine cooling system. In the
  cold season ensure that the strength of the FIAT
  PAR- AFLU 11 anti-freeze mixture is cor- rect.

OPERATION
Always operate the tractor at a safe speed for
the type of ground being worked. Reduce speed on
slopes and curves to prevent roll- over.

• Select the track width most suit- able to the
  work in hand, keeping tractor stability in mind.

When working on sloping ground, do not drive
too fast, parti- cularly when turning.

• Apply clutch gradually abrupt en- gagement,
  particularly uphill or under pull, could cause
  tractor to pitch dan- gerously. Immediately
  disengage clutch if front wheels start to rise.

Use extreme caution when op- erating with the
wheels near the edge of a slope.

• Do not coast downhill in neutral or with clutch
  disengaged.

When the tractor is moving, its operator should
always be sitting in the operator's seat. Do not
get on or off a moving tractor. Always depress
the brake pedal gently. Do not corner at high
speed.

wheeled implements.
USING AGRICULTURAL IMPLEMENTS AND MACHINERY
Unless your tractor is fitted with a regulation
passenger seat, never carry any riders, even
inslde the cab.
m Always use implements or ma- chinery rated for
use with your trac- tor. Never use machinery
designed for more powerful tractors.
Trailers should not be towed unless equipped
with an independ- ent braking system.
Respect the highway code during on-road transfers.
Always use drawbar when towing heavy loads. Do
not pull from 3-point hitch links as tractor
could pitch.
m Do not negotiate tight bends with the PTO
under heavy load as this could damage the drive
shaft universal joints.
Do not ride the brake and clutch pedals.
Latch brake pedals when roading otherwise
dangerous skidding may occur when braking. Do not
overwork brakes downshift to slow tractor.
When towing, do not negotiate bends with the
differential lock in, otherwise you may not be
able to steer the tractor.
m When coupling, never stand be- tween tractor
and implement while the tractor is being backed
up.

  gear before leaving the tractor seat. Always
  remove starter switch key before leaving tractor
  unattended.

• Park tractor on level ground if possible, engage
  a gear and apply parking brake.
• On gradients, apply parking brake and first gear
  uphill and reverse gear downhill. For greater
  safety, use the optional chock, especially with a

operated in strong sunlight, as fuel could expand
and escape. Any escaping fuel should be wiped off
immediately.

• Ensure that hydraulic system is not under
  pressure before discon- necting lines.

Hydraulic oil escaping under pressure could
cause serious per- sonal injury. When tracing oil
leaks wear protec- tive shields, glasses and
gloves.
Before attempting to inspect, clean, adjust,
repair or service the tractor or attached
implement in any way, ensure that the engine
is stopped, transmission in neutral, brakes are
applied, PTO is disen- gaged and all moving parts
are sta- tionary.
