The battery may only be replaced by a spe-
cialist dealer. The characteristic curve of
the battery charger set at the factory corre-
sponds to the battery provided and must not
be changed. Setting the characteristic curve
incorrectly can result in permanent damage to
the battery.
The battery type can be set by means of a switch located
at the bottom of the battery charger (covered by a green
adhesive label). Once the battery type has been set, the
green LED flashes at the beginning of the charging proc-
ess.
When handling the battery charger, the following safety
instructions must be observed:

Always place the rubber feet of the battery charger
on a level surface.

Protect the battery charger from direct sunlight to
prevent the charger from getting any warmer than it
already is.

be dry and well ventilated. Avoid letting dust and dirt
enter and affect the function of the battery charger.
