Starting with jump wires

Fig. 52
Caution
!
A wrong connection will cause severe damage
in the electric system.
Bridge the machine only with a 12 Volt auxilia-
l
ry battery.
When jump starting with an external battery
l
connect both plus poles first.
Then connect the ground cable first to the mi-
l
nus pole of the current supplying auxiliary bat-
tery and then to engine or chassis ground, as
far away from the battery as possible (Fig. 52).
Start as described under 'Starting the engine'.
l
Once the engine is running switch on a power-
l
ful consumer (working light, etc.).
Caution
!
If no powerful consumer is switched on volt-
age peaks may occur when separating the con-
necting cables between the batteries, which
could damage electrical components.
After starting disconnect the negative poles
l
(ground cable) first and the positive poles af-
ter.
Switch off the consumer.
