Starting with booster batteries
WARNING!
Because of current surge the batteries may explode
if a
fully charged battery is connected to a discharged battery.
Such an explosion can cause injuries.
When starting with booster batteries check that the booster batter-
ies or other power source has the same voltage as the standard
batteries.
Proceed as follows:
1 Turn OFF the battery master switch.
2 Remove the protections from the battery pole studs.
3 Connect two 12 V batteries as follows:
4 Connect one of the jump leads between (+) terminal ON the
battery of the machine and the (+) terminal on the booster bat-
tery.
5 Connect the other jump lead between the (-) terminal of the
booster battery and a grounding point on the machine.
6 Connect the batteries of the machine by turning ON the battery
master switch.
7 Start the engine with the start switch in the cab.
8 When the engine has started, first disconnect the jump lead
from the chassis connection on the machine, then disconnect
the other end of the jump lead from the (-) terminal on the
booster battery.
9 Finally disconnect the jump lead between the
(~)
terminals.
10 Re-install the battery pole stud protections.
