Starting Using Auxiliary
Batteries
WARNING!
Explosion hazard. Batteries contain and give off an
explosive gas which is highly flammable and
explosive. A short circuit, open flame or spark could
cause a violent explosion. Ventilate well.
WARNING!
Never confuse the positive and negative poles on the
batteries. Risk of arcing and explosion.
1 Check that the auxiliary battery has the same
voltage as the engine system voltage.
2 Connect the red positive cable to the plus (+)
terminal on the discharged battery and then to
the plus terminal on the auxiliary battery.
3 Connect the black start cable to the minus (–)
terminal on the auxiliary battery and to a place
a little distance away from the discharged
battery, e.g. the start motor's negative terminal.
WARNING!
The black jumper cable (–) must never come in
contact with the positive connection on the starter
motor.
4 Start the engine and let it run at fast idle for
approximately 10 minutes to charge the
batteries. Make sure there is no extra equipment
connected to the electrical system.
WARNING!
Working with or approaching a running 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 bend over any of the batteries either.
5 Turn off the engine. Remove the start cables in
the exact opposite order to their connection.
