6.6 Safety measures during maintenance and repair operations
6.6.1 General safety measures
It is forbidden to dismount the hood side panels and/or open the hood mask of the
tractor with the engine running.
Maintenance (repair) operations shall be carried out only if the engine is not running
and FPTO and RPTO are disengaged. Hinged implements shall be grounded, the tractor
shall be stopped with the parking break.
Adhere to the safety requirements during application of the lift-and-carry means.
During inspection of units under control and adjustment use the portable lamp with
voltage of 36V. The lamp shall be protected by wire guard.
Tools and accessories for MS shall be properly operating, answer the purpose and
ensure safe operation.
In order to avoid injury be careful draining (refilling) the coolant from the engine cool-
ing system, the hot oil from the engine, hydraulic systems of LL and HSC, transmission
bodies, and FPTO and FDA reducing gears. Avoid contact with hot surfaces of the above-
mentioned 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 make alterations in the tractor or its separate parts design without sanction of
the manufacturing works. Otherwise the tractor after-sales service warranty is no longer
valid.
6.6.2 Safety precautions for exclusion of hazardous situations, related to an accumulator
battery and a fuel tank
.
During maintenance of the accumulator batteries, do the following:
- avoid skin contact with electrolyte;
- clean the battery with wiping material moistened with aqua ammonia solution (ammo-
nium hydroxide);
- while checking the electrolyte level, refill distilled water only;
- do not check the battery charge by means of the terminal short circuit;
- do not connect the accumulator battery with reversed polarity.
In order to avoid damaging of the electronic units of the electrical facilities and electrical
control systems, observe the following safety precautions:
- do not disconnect AB outputs with the engine running. It will cause peak voltage in
charging circuit and will result in inevitable failure of the diodes and transistors;
- do not disconnect 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 failure of the diodes and transistors;
- do not connect the AB in the electrical equipment system until the outputs/inputs polarity
and voltage are checked;
