BATTERY MAINTENANCE
5. Check the battery terminals periodically to ensure that
they are in good condition.

white pattern appears inside the battery or paste has
accumulated at the bottom, replace the battery.
8. If the machine will not be in operation for a long period
of time, charge the battery sufficiently, tighten all caps
correctly, store in cool dry place and check the battery
charge level every month to maintain the performance
of the battery.
