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 motor 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.
• 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 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.

Cleaning the tractor

Clean the tractor regularly.
Before you start:
Turn the ignition key to the STOP position before
washing.
NOTE: Protect the environment by following the
environmental regulations. The washing place must
have a separator outlet when using detergents.
It is best to wash the new tractor for the first time a week
after the start-up. Avoid rubbing the surface of the
tractor too hard during the first months.
NOTE: Do not wax the paint work of the new tractor
before the initial washing.
• Wash the tractor using a pressure washer.
Keep the nozzle of the pressure washer at least 30
cm from the sealing points and paint work. The
temperature of the washing water must not be
higher than 50°C.
NOTE: Do not use special nozzles, such as turbo
nozzles, when washing. Follow the instructions of
the pressure washer manufacturer.
• Do not let the water get into the cab air filter when
washing the cab sides.
The cab air filter is in the side plate of the roof,
usually on the left.
• Do not wash the inside of the cab with a pressure
washer or running water.
• Do not point the pressure washer towards electrical
equipment, electrical connectors, lead-through
points, bearings, seals and locks.
Use lower pressure (6,5 MPa / 65 bar) and point the
water diagonally to the above points. Do not point
the pressure washer towards the radar sensor
(minimum distance 1 m and maximum pressure 6,5
MPa / 65 bar).
