Introduction and Safety in the Workshop
OPERATIONAL CONSIDERATIONS
• Stop the engine, if at all possible, before performing
any service.
• Place a warning sign on self propelled equipment
which, due for service or overhaul, would be
dangerous to start. Disconnect the battery leads if
leaving such a unit unattended and remove the key.
• DO NOT attempt to start the engine while standing
beside the tractor or attempt to by-pass the safety start
switch. Make a practise of checking that neutral start
switches are functioning correctly.
• Avoid prolonged running of the engine in a closed
building or in an area with inadequate ventilation as
exhaust fumes are highly toxic.
• Always turn the radiator cap to the first stop to allow
pressure in the system to dissipate when the coolant is
hot.
• Never work beneath a tractor which is on soft ground.
Always take the unit to an area which has a hard level
working surface - concrete is preferred.
• If it is found necessary to raise the equipment for ease
of servicing or repair, make sure that safe and stable
supports are installed, beneath axle housings,
casings, etc., before commencing work.
• Certain repair or overhaul procedures may necessitate
'Separating the tractor', either at the engine gearbox or
gearbox/rear axle locations. These operations are
simplified by the use of the Tractor Splitting Kit/Stands
(Use the Massey Ferguson MF.3012 Tractor Splitting
Track, also available, MF.3013 Cab Stands). Should
this equipment not be available, then every
consideration must be given to stability, balance and
weight of the components, especially if a cab is
installed.
• Use footsteps or working platforms when servicing
those areas that are not within easy reach.
• Cleanliness of the tractor hydraulic system is essential
for optimum performance. When carrying out service
and repairs plug all hose ends and component
connections to prevent dirt entry.
• Clean the exterior of all components before carrying
out any form of repair. Dirt and abrasive dust can
reduce the efficiency and working life of a component
and lead to costly replacement. Use of high pressure
washer or steam cleaner is recommended.
• Before loosening any hoses or tubes connecting
implements to remote control valves, etc., switch off
the engine, remove all pressure in the lines by
operating levers several times. This will remove the
danger of personal injury by oil pressure.
• Prior to pressure testing, make sure all hoses and
connectors not only of the equipment, but also those of
the test equipment, are in good condition and tightly
sealed. Pressure readings must be taken with the
gauges specified. The correct procedure should be
rigidly observed to prevent damage to the system or
equipment, and to eliminate the possibility of personal
injury.
• Hydraulic fluid escaping under pressure can have
enough force to penetrate the human skin. To locate a
leak under pressure, use a small piece of cardboard,
never use your hands. If you are injected with hydraulic
fluid seek medical help immediately.
• When equipment or implements are required to be
attached to the hydraulic linkage, either for testing
purposes or for transportation, the 'Position Control'
should be used.
• Always lower equipment to the ground when leaving
the tractor.
• If high lift attachments are installed on a tractor beware
of overhead power, electric or telephone cables when
travelling. Drop the attachment near to ground level to
increase stability and minimise risks.
• DO NOT park or attempt to service the equipment on
an incline. If unavoidable, take extra care and chock all
wheels.
• Observe recommended precautions as indicated in
this Service Manual when dismantling the air
conditioning system as escaping refrigerant can
cause frostbite.
• Prior to removing wheels and tyres from a tractor,
check to determine whether additional ballast (liquid
or weights) has been added. Seek assistance and use
suitable equipment to support the weight of the wheel
assembly. Store the wheel so that they cannot fall over
and cause injury.
• When inflating tyres beware of over inflation -
constantly check the pressure. Over inflation can
cause tyres to burst and result in personal injury.
Heed these safety precautions, and the ones found in this
manual, and you will protect yourself accordingly.
Disregard them and you may become injured for life.
SERVICING TECHNIQUES
Service Safety
Appropriate service methods and proper repair
procedures are essential for the safe, reliable operation of
all farm machinery as well as the personal safety of the
individual doing the work.
