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.

  will

Sa7eiy Precautions 7'H/S SYMBOL IS YOUR SAFETY
ALERT SUN
m Tractor should be operated only by responsible
persons suitably trained and duly authorized.
It means
Keep a first aid kit handy.
ATTENTION - DANGER YOUR SAFETY IS INVOLVED
Read and heed all safety instructions carrying
the signal words NOTE, CAU- r/ox and DANGER.
Do not work with loose garments that could get
caught in moving parts. Check that all rotating
parts connected to the PTO shaft are well
shielded.
m Read this manual thoroughly be- fore
attempting to start, operate, service or
refuel the tractor. A few minutes reading will
save time and trouble later.
You tractor was designed with safety very much in
mind. However, there is no real substitute for
cau- tion and attention in preventing acci-
dents. Once an accident has hap- pened it is too
late to think about what you should have done.
Remember that your tractor has been designed
exclusively for agri- cultural use. Any other
application must first be authorized by the man-
ufacturer.
Read and heed all machine- mounted safety
decals before refuel- ing or servicing the
machine and re- place any missing decals.
16
Do not attempt to increase max. engine rpm by
altering injection pump governor setting.
TRACTOR STARTING
Prior to starting the engine check that
parking brake is on and gear and PTO levers are
in neutral, even if your tractor is fitted with a
start inhibiting device. Never by- pass start
inhibitor switch. Consult trained servicing
personnel if start inhibitor is not operating
correctly.
Do not alter relief valve setting of hydraulic
systems (power steering, hydraulic lift, remote
control valves, etc.).
Do not run engine in a closed building without
adeguate ventilation as exhaust fumes are
dangerous.
Do not operate tractor if you feel unwell. Stop
working rather than risk an accident.
Make sure that all implements are fully lowered
before starting.
Ensure that there are no persons or obstacles
within range before starting the tractor.
Ensure that all guards and pro- tective devices
are correctly in- stalled before starting the
tractor (ROPS frame or cab, hood side pan- els,
PTO guard, front axle drive shaft guard etc.).
Always use steps and grab hand- les when getting
in or out of the cab.
Never work without roll-over pro- tection the
frame or cab correctly fit- ted to tractor. Check
that fasteners are not loose and that the frame
is not damaged in any way. Do not al- ter cab by
welding or drilling.
Do not attempt to start or mano- euvre the
tractor unless sitting in opeator's seat.

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.
OPERATION m 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.
a Engage clutch pedal gradually abrupt
engagement, particularly up- hill or under pull,
could cause tractor to pitch dangerously.
Immediately disengage clutch if front wheels
start to rise.
Use extreme caution when op- erating with the
wheels near the edge of a slope.
m 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. m Do not corner at high

TOWING
m Adjust the towing attachment correctly to
maintain tractor stability. See note on page 45.
m Drive slowly when towing heavy trailers or
wheeled implements.
USING AGRICULTURAL IMPLEMENTS AND MACHINERY
m Unless your tractor is fitted with a regulation
passenger seat, never carry passengers, even
inside the cab.
m Always use implements or mac- hinery rated for
use with your trac- tor. Never use machinery
designed for more powerful tractors.
m Trailers should not be towed unless
equipped with an independ- ent braking system.
m Respect the highway code dur- ing on-road
manoeuvers.
m 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.
m Do not ride the brake and clutch pedals.
m Latch brake pedals during on- road transfer
otherwise dangerous skidding may occur when
braking. Do not overwork brakes downshift to
slow tractor.
m 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.

apply parking brake and first gear uphill and
reverse gear downhill. For greater safety, use
the optional chock, especially with a trailer
on tow.
a Never operate a PTO driven implement
without first ensuring that no one is on or too
near the mac- hine. Check that all rotating parts
con- nected to the PTO shaft are well shielded.
