Maintenance and care
Safety instructions
WARNING!
Danger if the starter battery is not
handled correctly!
The following points must be complied
with to avoid the dangers arising from in-
correct handling of the battery!
■
Do not store the starter battery in the immedi-
ate vicinity of naked flames, do not burn it or
place it on heaters. Risk of explosion.
■
Store the starter battery in a cool, dry room
(10 - 15 °C) over the winter. Avoid storing at
temperatures below the freezing point.
■
Do not leave the starter battery without
charge for a long period. If the starter battery
is not used for a long period, it should be
charged using a suitable charger.
■
Do not smash the starter battery. The electro-
lyte (sulphuric acid) causes chemical burns to
the skin and clothing – immediately rinse
away with plenty of water.
■
Keep the starter battery clean. Only wipe
clean with a dry cloth. Do not use water, pet-
rol, thinners or similar for this purpose.
■
Keep the connection terminals clean and
grease them with terminal grease.
■
Do not short-circuit the connection terminals.
Charging the starter battery
Charging is required:
■
Before putting into storage before the winter
break.
■
If the machine will not be used for a long time
(longer than 3 months).
WARNING!
Danger if the starter battery is not
charged correctly!
The charging current of the charger
must not exceed 5 A, and the charging
voltage can only be max. 14.4 V. Risk of
explosion of the starter battery if the
charging current is more powerful!
Always remove the ignition key before
starting work on the battery.
We recommend charging this maintenance-free,
gas-tight starter battery using a specifically suit-
able charger (which can be obtained through re-
tail outlets).
Comply with the operating instructions of the
charger manufacturer before and during charging
of the starter battery.
CAUTION!
Danger of a short circuit!
To avoid a short circuit, always discon-
nect the negative cable (-) of the battery
first, and reconnect it last!
Always remove the ignition key before
starting work on the battery!
1. Remove the ignition key (05).
2. Open the engine cover.
3. Connect the charger terminals to the connec-
tion terminals of the battery.
NOTE
Check the polarity:
■
Red terminal = positive terminal (+)
■
Black terminal = negative terminal (-)
4. Connect the charger to the mains and switch
it on.
