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 vio-
lent 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 volt-
age as the engine system voltage.
2 Connect the red positive cable to the plus (+) ter-
minal on the discharged battery and then to the plus
terminal on the auxiliary battery.
3 Connect the black start cable to the minus (–) ter-
minal 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!
Under no circumstances may the black jumper cabel
(–) come in contact with the positive connection on the
starter motor.
4 Start the engine and let it run at fast idle for approx-
imately 10 minutes to charge the batteries. Make
sure there is no extra equipment connected to the
electrical system.
WARNING!
Working with or going close to 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.
