Important safety information
Note
An explosive gas mixture can escape from the
battery when charging and when jump starting.
There is a risk of explosion!
Avoid all fire, open flames, sparks and smoking.
Ensure adequate ventilation when charging and
when jump starting. Do not lean over the battery.
Note
Discharged batteries may freeze at temperatures
around the freezing point. If you jump start or charge
the battery, an explosive gas mixture can escape
from it. There is a risk of explosion!
Always let a frozen battery thaw out before charging
it or jump starting.
i
Observe the following instructions, otherwise you
could damage the batteries or electronic
components:
• Do not use a quick charger for jump starting.
• If you are using a mobile charger (batteries with
power supply unit), pull the mains plug before jump
starting.
• Only allow for starting assistance from vehicles with a
24 V system.
• Use jumper cables that are protected against reverse
polarity and that have a cross section of around 35–
50 mm² and insulated terminal clamps.
• A discharged battery can freeze if the outside
temperature has dropped below -10 ℃. In this case,
do not start the engine. Let the batteries thaw out
first.
i
Do not connect the NEGATIVE terminal of the
jumper cable to the vehicle frame. The engine,
transmission or electrical and electronic components
could otherwise be damaged.
i
When removing the jumper cables, leave the engine
of the power-receiving vehicle running at idle. This
avoids damaging the electrical and electronic
components in the vehicle.
After jump starting, have the batteries checked at a
qualified workshop.
