Performing maintenance tasks
Follow these instructions when maintaining.
Before you start:
•
Test drive the tractor and test that all instruments
and controls are working properly.
•
Always stop the engine before starting the work.
•
Park the tractor on level ground, especially when
doing oil checks.
•
Apply the parking brake to ensure that the tractor
cannot move.
NOTE: If the ground is uneven, block the wheels.
•
Wash down the tractor so that the service work
can be done easily and quicker.
Observe that if the tractor has extra equipment like
towing device, air conditioning, air pressure brakes
and so on, the periodical maintenance and checks for
them must also be carried out.
Follow the instructions concerning general service
tasks:
•
Observe the utmost cleanliness in all maintenance
work.
Thoroughly wipe off filler caps and plugs as well
as surrounding parts of the tractor before filling up
with fuel or oil.
CAUTION: Keep the engine surface
clean in order to avoid the risk of fire.
•
Check the oil level.
Be sure that the engine and oil have cooled down
before checking the oil level. The oil must have
run down to the bottom of the oil sump before the
operation.
•
Open the radiator cap with care when the engine
is hot as the cooling system is pressurized.
WARNING: Coolant may be hot and
under high pressure.
•
Always disconnect the negative (-) battery cable
when servicing or repairing the electric system.
IMPORTANT: Make sure that the main power is
turned off before disconnecting or reconnecting
the battery.
•
When changing the oil and filters, check their
appearance.
Large amounts of dirt (for example heavily
clogged filters) can point to a fault which could
cause extensive and costly repairs if not corrected
in time.
WARNING: When changing the oil,
notice that the oil can be very hot
when it drains from the tractor.
WARNING: Avoid touching the
exhaust manifold, turbocharger and
other hot parts of the engine.
•
Use proper gloves and other protection for the
noxious chemicals.
Fuel, lubricating oil and coolant cause irritation to
the skin if they are in contact with it for long
periods.
•
Dispose of the waste oil, liquid waste, oil filters
and batteries properly and handle them carefully.
After you finish:
NOTE: After completion of service work, reinstall all
shields and covers.
