5 MAINTENANCE
5.1 General instructions
Maintenance service (MS) is necessary for maintaining the tractor in operable state during
operational processes. Failure to observe the specified intervals of MS and bad quality of
MS may result in reduction of tractor life significantly, increase of failures, engine power
loss and increase in expenses for tractor operation. An operator shall carry out daily in-
spection of the tractor, checking fasteners for tightening, fuel, liquid, and oil leakage, dirt
and other deposits accumulation, which can cause operating troubles, ignition or acci-
dents.
Notes about performance of maintenance services shall be made in the tractor service
book.
Observe storage precautions and waste recovery rules. Never discharge used liquid to the
ground. Use special tanks for safe storage of waste.
WARNING: WHILE CARRYING OUT MAINTENANCE AND REPAIR SERVICES, AL-
WAYS COMPLY WITH SAFETY PRECAUTIONS, LISTED IN SUBSECTION 5.6 “SAFE-
TY PRECAUTIONS WHILE MAINTENANCE AND REPAIR SERVICES”!
ATTENTION: IF THERE ARE NO SPECIAL INSTRUCTIONS, BEFORE STARTING ANY
MAINTENANCE OR ADJUSTMENT SERVICES, ETC., STOP THE ENGINE AND EN-
GAGE PARKING BRAKES. IN CASE SAFETY GUARDS AND COVERS ARE OFF,
MAKE SURE THEY ARE MOUNTED BACK AFTER CONDUCTING MAINTENANCE
SERVICES, BEFORE YOU START OPERATING THE TRACTOR!
In the process of conducting maintenance services of the hydraulic lift system, steering,
and the transmission hydraulic system, it is strictly required to observe oil change and filter
replacement intervals. It is not allowed to use oil for filling (refilling), not specified in the
tractor operation manual.
Before refilling, replacing or cleaning filter cartridges, it is necessary to clean filler plugs,
necks and caps, and adjoining surfaces from dirt and dust. While filter cartridge replace-
ment, wash internal surfaces of filter housings and caps with the diesel fuel.
While tractor coupling with hydraulically-operated implements, it is necessary to clean
clutches, couplings, adapting pipes and other connecting parts of the implement and the
tractor thoroughly.
In case the hydraulic system is operated with hydraulically-operated implements filled with
oil origin of which is unknown, the oil in the implement shall be replaced by the oil filled into
the tractor hydraulic lift system.
Purity of oil in the hydraulic system ensures its fail-safe operation.
