5.6 Safety measures during maintenance and repair operations
5.6.1 General safety requirements
It is forbidden to lift tractor hood with the engine running.
Maintenance (repair) operations shall be carried out only if the engine is not running
and rear PTO shafts are disengaged. Attached implements shall be grounded, the tractor
shall be stopped with the parking brake.
Adhere to safety requirements during the use of lift-and-carry means.
During inspection of the objects of control and adjustment use a portable lamp with
max. voltage of 36V. The lamp shall be protected by wire guard.
Tools and accessories for work shall be properly operating, comply with the purpose
and ensure safe operation.
You should wear protective goggles while doing all types of work.
In order to avoid injury be careful draining (refilling) the coolant from the engine
cooling system, hot oil from the engine, hydraulic systems of LL and HSC, transmission
and FDA housings. Avoid contact with hot surfaces of the abovementioned units.
Mounting and dismounting of the engine shall be carried out by means of a rope,
fastened to eye-bolts on the engine.
Do not introduce alterations in the tractor or its separate parts without approval of
the manufacturing plant. Otherwise the tractor warranty service shall no longer be valid
and all possible claims shall not be accepted even after the warranty period is over.
ATTENTION: AFTER PERFORMING MAINTENANCE AND/OR REPAIR, REIN-
STALL ALL REMOVED TRACTOR ELEMENTS. STARTING THE ENGINE AND OPER-
ATING THE TRACTOR WITH UNINSTALLED ELEMENTS PROVIDED BY THE DESIGN
OF THE TRACTOR RELEASE THE MANUFACTURER FROM RESPONSIBILITY FOR
POSSIBLE SUBSEQUENT INJURIES OF THE OPERATOR AND DAMAGE TO THE
TRACTOR.
5.6.2 Safety precautions for exclusion of hazardous situations related to accumula-
tor battery and fuel tank.
During maintenance of the accumulator battery observe the following:
- avoid skin contact with electrolyte;
- clean the battery with wiping material moistened with aqua ammonia solution
(ammonium hydroxide);
- during examination of electrolyte level, refill distilled water only;
- do not check the battery charge condition by means of the terminal short circuit;
- do not connect the accumulator battery with reversed polarity.
In order to avoid damaging to the electronic units of the electrical equipment and
electrical control systems adhere to the following safety precautions:
- do not disconnect the AB outputs with the engine running. It will cause peak volt-
age in charging circuit and will result in inevitable failure of diodes and transistors;
- do not disconnect the electric wires when the engine is running and electric
switches are “on”;
- do not cause short circuit by incorrect wire connection. Short circuit or incorrect
polarity will result in damage to diodes and transistors;
- do not connect the AB to the electrical equipment system until the polarity and
voltage of the outputs are checked;
- do not check the electric current by spark test as it will result in immediate break-
down of transistors;
Repair and welding operations shall be carried out while the AB switch is “off”.
To avoid inflammation or explosion hazard, prevent the fuel tank, engine fuel sys-
tem and accumulator battery from being close to the open flame sources.
Simultaneous touching of tips and bare parts of positive and negative wires is not
recommended to avoid electrical shock.
