WARNING
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.
Ë
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 jump start from vehicles with a 24 V system.
•
Use jumper cables that are protected against
reverse polarity and have a cross section of about
35–50 mm² and insulated terminal clamps.
•
If the outside temperature has dropped below
-10°C, discharged batteries may freeze. In this
case, do not start the engine. Let the batteries
thaw out first.
Ë
Do not connect the negative terminal clamp of the
jumper cable to the chassis frame. The engine,
transmission or electrical and electronic components
could otherwise be damaged.
Ë
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.
