››› page 203.
● The non-insulated parts of the battery
clamp
s must not be allowed to touch. Addi-
tionally, the jump lead attached to the posi-
tive battery terminal must not touch metal
parts of the vehicle. Risk of short circuit!
● Do not connect the negative lead to the
negativ
e terminal of the discharged battery.
In the event of sparks when starting the en-
gine, the explosive gas given off by the bat-
tery could catch fire.
● Position the jump leads in such a way that
they cannot
come into contact with any mov-
ing parts in the engine compartment.
● Do not bend over the battery. Risk of acid
burns!
● The s
crew plugs on the battery cells must
be scr
ewed in firmly.
● Keep sources of fire (flames, lit cigarettes,
etc.) a
way from the battery. - Risk of explo-
sion!
● Never use the jump leads on batteries in
which the electr
olyte level is too low. Risk of
explosion and acid burns. Note
● The v ehic
les must not touch each other, as
electricity could flow as soon as the positive
terminals are connected. ●
The dis c
harged battery must be properly
connected to the vehicle electrical system.
● The jump leads should be checked in a spe-
cia
list vehicle battery shop. How to jump start: description
