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 removing the battery, always undo the
negative cable first.
When fitting the battery, always connect the
positive cable first.
Dispose of the old battery in the approved
environmentally suitable manner – batteries
contain toxic lead.
When carrying out electrical welding on
the machine, disconnect the battery’s
negative cable and then all the electrical
connections leading to the alternator.
