3.21 Jump-starting the engine (external battery)
Safety instructions regarding external starting aids
Risk of explosion due to jump-starting with a frozen battery
☞Immediately replace the frozen battery by a new one.
Risk of short circuit if the wheel loader and the vehicle giving the jump start
have contact!
☞The battery jumper cable connected to the positive + terminal of the starting
battery must never be brought into connection with electrically conductive
vehicle parts.
Risk of short circuit and sparks!
☞The external power source must deliver 12 V; higher supply voltages will
damage the electrical system of the vehicles!
☞Use only authorized battery jumper cables that conform to the safety
requirements and that are in perfect condition!
☞Route the battery jumper cables so they cannot catch on rotating components in
the engine compartment!
Providing external starting aid
☞Drive the jump-starting vehicle close enough to the loader so that the jump leads can
reach to connect the two batteries
☞Let the engine of the jump-starting vehicle run
☞First connect one end of the red cable (+) to the + terminal of the discharged battery,
then connect the other end to the + terminal of the starting battery
☞Connect one end of the black cable (−) to the – terminal of the starting battery
☞Connect the other end of the black cable (−) to a solid metal component fimly screwed
on the engine block or onto the engine block itself. Do not connect it to the negative
terminal of the empty battery, as otherwise explosive gas emerging from the battery
can ignite if sparks are formed!
☞Start the diesel engine of the machine with the empty battery
Once the engine has started:
☞With the engine running, disconnect both battery jumper cables in exactly the reverse
order (first the – terminal, then the + terminal). This prevents sparking near the battery!
