Starting with booster batteries
WARNING
Risk of explosion.
Batteries could explode due to the current surge if
a fully charged battery is connected to a completely
discharged or frozen battery.
Do not boost start a machine with a completely
discharged or frozen battery.
When starting with booster batteries, check that the
booster batteries or other power source have the
same voltage as the batteries of the machine. If the
batteries in another machine are used the engine of
that machine must be turned off.
NOTICE
Do not attempt to start the engine while the battery
charger is still connected to the mains. This may
cause serious damage to the electronic control
units.
1 Turn OFF the battery disconnect switch.
2 Remove the protections from the battery pole
studs.
Connect two 12 V batteries as follows :
3 Connect one of the jump leads between (+)
terminal on the battery of the machine and the
(+) terminal on the booster battery.
4 Connect the other jump lead between the (-)
terminal of the booster battery and a grounding
point on the machine.
NOTICE
Do not connect ground to the undercarriage on the
machine. This may seriously damage the swing
bearing.
