Starting with booster cables 3
When starting the engine with booster cables, proceed as indicated below.
Connecting and disconnecting the booster cables
WARNING
q
When connecting the cables, avoid any contact
between the positive cable (+) and the negative cable
(–).
q
When starting the engine with booster cables, always
wear safety goggles.
q
Take care to avoid any contact between the machine to
be started and the machine used as starting aid, in
order to avoid sparks and therefore the explosion of
the hydrogen produced by the batteries. The explosion
of hydrogen causes serious damage and injury.
q
Take care not to make any mistake when connecting
the booster cables. In the last connection (to the turret
frame) a spark is generated, therefore it is advisable to
connect the cable as far from the battery as possible.
(In any case, avoid the attachments, since they are
poor conductors).
q
When removing the booster cables, take care to avoid
any contact of the clamps with each other or with the
machine frame.
NOTICE
q
The booster cables and the clamps must be sized according to the dimensions of the battery.
q
The battery to be used to start the engine must have greater capacity or at least the same capacity as
the battery of the machine to be started.
q
The starting system of this machine is powered at 24 V. Therefore, use a 24V battery for the machine
to be used as power source.
q
Make sure that cables and clamps are neither corroded, nor damaged.
q
Make sure that cables and clamps are secured firmly.
q
Make sure that the safety levers of both machines are in the LOCK position (L).
q
Make sure that all the levers are in neutral.
q
Before connecting two machines with battery cables, turn the non operating battery disengagement
switch of the machine to OFF and remove the switch of the battery disengagement switch in order to
prevent possible damages to the machine electrical system.
