Operating instructions
4. Connect the other end of the black jump lead
component which is bolted on to the engine block, or onto the
engine block itself of the vehicle with the flat battery. Do not
connect it to a point near the battery ⇒
5. Position the leads in such a way that they cannot come into
contact with any moving parts in the engine compartment.
Starting
6. Start the engine of the vehicle with the boosting battery and let
it run at idling speed.
7. Start the engine of the car with the flat battery and wait one or
two minutes until the engine is "running".
Removing the jump leads
8. Before you remove the jump leads, switch off the headlights (if
they are switched on).
9. Turn on the heater blower and heated rear window in the vehicle
with the flat battery. This helps minimise voltage peaks which are
generated when the leads are disconnected.
10. When the engine is running, disconnect the leads in reverse
order to the details given above.
Connect the battery clamps so they have good metal-to-metal contact with
the battery terminals.
If the engine fails to start, switch off the starter after about 10 seconds and
try again after about half a minute.
