632 If something happens
Starting with starting cables
Always use another vehicle or other batteries to help
start the engine.
1
Turn the ignition key to the 0 position.
2
Make sure that the help start battery has 24 V
total voltage or 24 V system voltage.
3
Switch off the engine of the assisting vehicle and
make sure that the vehicles do not touch one
another.
4
Connect one of the clamps on the red cable to the
positive terminal on the help battery. The positive
pole is marked in red, P or +.
5
Connect the other clamp on the red cable to the
positive terminal on the battery of the vehicle that
needs help. The positive pole is marked in red, P
or +.
6
Connect one clamp on the black cable to the
negative terminal of the help battery marked in
blue, N or -.
7
Connect the other clamp on the black cable to a
place - an earth - some distance from the battery
of the vehicle which needs help.
8
Start the engine on the "assisting vehicle". Let
the engine run for some minutes at a higher speed
than normal (about 1000 rpm).
9
Start the engine on the other vehicle.
10
Remove the clamp on the black cable from the
earth point.
11
Remove the clamp on the black cable from the
negative terminal on the help battery.
12
Remove the red cable.
Caution!
So-called start help units must not
be connected, because these can
give very high voltages, which
can in turn damage control units.
Note!
After the truck has been started by
using starting cables, the batteries
should be charged with a battery
charger. It takes about 20 hours to
fully charge a battery. An alternator
can never charge the battery to
100%; in favourable circumstances a
maximum level of 90% can be
achieved.
