CONNECTING THE JUMPER CABLES
Connect the red jumper cable to the positive clamp
of the discharged battery (1) and then to the positive
clamp of the booster battery (2).
Connect the black jumper cable first to the negative
clamp of the booster battery (3) and then to a bright-
metal point on the receiving machine (4).
STARTING THE ENGINE
Start the engine of the supplying machine and run it
with stepped-up revolutions.
Start the engine of the receiving machine (with dis-
charged battery). If the engine does not start up
after 15 seconds, wait one minute before restarting.
Once the engine has started up, proceed as follows:
Switch on some high-consumption users, e.g. com-
plete lighting system, blower on stage 3 and the air-
conditioning system if present. All this prevents that
when the cables are detached, peaks of current are
generated, that could on their turn damage the elec-
tronic units.
Disconnect battery jumper cables in this way:
- negative terminal on receiving machine (4);
- negative terminal on delivering machine (3);
- positive terminal on receiving machine (2);
- positive terminal on delivering machine (1).
Switch off high-consumption units again.
Run the engine at moderate speed for about half an
hour. Batteries are partially re-charged.
Have the electrical system of the machine checked,
to determine why the batteries were discharged.
