BATTERY MAINTENANCE
SERVICE INFORMATION
- Do not reverse the polarity of the battery.
This could cause damage to some sensitive
electronic devices.
- The battery produces explosive gases. Do
not allow sparks or naked flames near the
battery especially when charging.
- The electrolyte contains sulphuric acid. If this
comes into contact with the skin, it produces
burns. If this occurs, wash the affected area
with plenty of water and consult a doctor.
- To avoid causing damage to sensitive equip-
ment, do not disconnect the battery cables or
other connections while the ignition switch is
in the ON position, or while the engine is run-
ning.
- Whenever possible charge the battery
slowly. Rapid charging should be used only
in cases of emergency.
- Take the battery out of the machine in order
to charge it.
- Keep the breather tube free of obstruction,
particularly while charging.
- Batteries if left unused lose their charge. Do
not leave the battery for more than one
month without giving it a top-up charge, and
after one month charge the battery every two
weeks.

DENSITY OF THE ELECTROLYTE
- Check the level of the electrolyte
periodically and if the level is low,
add distilled water.
- Check each cell with a densitometer.
- Density with fully charged battery at
20ºC, 1.26 to 1.28.
- With values of lower than 1.26, char-
ge the battery.
- Check that the density does not vary
by more that 0.05 between the bat-
tery cells.
- The density of the electrolyte varies
with the temperature: please refer to
the attached table.
