Remove the cell covers and check that the fluid level is
about 10 mm (0.4 in) above the plates. Check the level
in all the cells. If the level is lower, top up to the correct
level with distilled water. If the ambient air temperature
is below freezing point, the engine should be run for a
while after the distilled water is added, otherwise there
is a risk that the water might freeze.
Check that the ventilation holes in the cell covers are
not blocked, then refit the covers.
The cable terminals must be properly tightened and
clean. Corroded cable connections should be cleaned
and greased with alkaline Vaseline.
When disconnecting the battery, always
disconnect the negative cable first. When
connecting the battery, always connect the
positive cable first.
Discard used batteries properly. Batteries
contain lead, which is detrimental to the envi-
ronment.
Before doing any electric welding on the
machine, disconnect the battery ground
cable and then all electrical connections to
the alternator.
Make sure there are no open flame in the
vicinity when checking the electrolyte level.
An explosive gas is formed in the battery
during the charging process.
Lift up the engine compartment cover and undo the
quick-release screws (1).
Raise the battery cover (2).
Dry the upper face of the battery.
Use protective goggles. The battery con-
tains corrosive acid. In the event of con-
tact, rinse with water.
Inspect refrigerant hoses and connections and make
sure that there are no signs of oil film that could indicate
leakage of refrigerant.
