Guidelines For Safe Use Of Leveling Jacks And Statement Of Proper Places For Their Installation - Belarus 1822.3 Operator's Manual

- do not connect the accumulator battery with reversed polarity.
In order to avoid damaging of the electronic units of the electrical facilities and elec-
trical 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 facilities system until the outputs/inputs po-
larity and voltage are checked;
- do not check the electric current by spark test as it can result in immediate break-
down of transistors.
Repair operations connected with application of electric welding for the tractor shall
be carried out while the AB switch is off.
To avoid ignition or explosion hazard, prevent the fuel tank, engine fuel system and
accumulator batteries from being close to the open flame sources.
6.6.3 Guidelines for safe use of leveling jacks and statement of proper places
for their installation
Use leveling jacks to lift tractor, and after lifting insert backing blocks and limit stops

Places for leveling jack installation on the tractor are marked by a sign shown in fig-
ure 6.6.1.
