Starting with auxiliary batteries
WARNING! Ventilate well. Batteries contain and
give off an explosive gas which is highly flamma-
ble and explosive. A short circuit, open flame or
spark could cause a violent explosion.
WARNING! Never confuse the positive and neg-
ative poles on the batteries. Risk of arcing and
explosion.
1. Check that the rated voltage of the help start bat-
tery is the same as the system voltage of the en-
gine.
2. Connect the red jumper cable to the positive pole
(+) of the flat battery, and then to the positive pole
of the help start battery.
3. Connect the black jumper cable to the negative
pole (–) of the help start battery, and then to a
place some distance from the flat batteries, such
as the negative connection on the starter motor.
WARNING! Under no circumstances may the
black jumper cable (–) come into contact with the
positive connection on the starter motor.
4. Start the engine and run at a fast idle for about
ten minutes to charge the batteries. Make sure
that there are no extra accessories connected to
the electrical system.
WARNING! Working with, or going close to a run-
ning engine is a safety risk. Watch out for rotating
components and hot surfaces.
WARNING! Do not touch the connections during
the start attempt: Risk of arcing. Do not stand
bending over any of the batteries either.
5. Stop the engine. Remove the jumper cables in the
exact reverse order from installation.
