electrolyte level or to refill water; simply
keep the battery poles clean and
slightly greased with acid-free grease if
necessary.
To access battery, remove the front
right plastic cover.
To remove the battery, first disconnect
the negative (-) and then the positive

longer period of standstill, remove the
battery and recharge it every month in a
slow charge. Storage temperature: 0-
35ºC. Do not expose it to direct sun
radiation.
