Caution
!
A wrong connection will cause severe damage in
the electric system.
Only use a 12 Volt battery to bridge the machine.
l
When jump starting with an external battery connect
l
both plus poles first.
Then connect the ground cable first to the minus
l
pole of the current supplying battery and then to en-
gine or chassis ground, as far away from the battery
as possible(Fig. 2).
Start as described under 'Starting the engine'.
l
Once the engine is running switch on a powerful
l
consumer (working light, etc.).
Caution
!
If no powerful consumer is switched on voltage
peaks may occur when separating the connecting
cables between the batteries, which could dam-
age electrical components.
After starting disconnect the negative poles (ground
l
cable) first and the positive poles after.
Switch off the consumer.
