Note: Use only insulated booster cables with a cross section of at least
16 mm².
The following connection sequence must be used when starting with an external
battery:
1. Clamp red booster cable to positive pole (1) of the discharged battery using
a pair of clamping pliers.
2. Clamp the other pair of clamping pliers of the red booster cable to the donor
battery's positive pole (2).
3. Clamp black booster cable to negative pole (3) of the donor battery using a
pair of clamping pliers.
4. Attach the other clamping pliers of the black booster cable to the ground con-
nector (4) of the equipment, e.g. the engine support.
5. Start the engine and allow it to warm up (max. 15 seconds).
WARNING
Danger of explosion due to detonating gas.
Injury may result from spraying acid.
f Wear safety glasses and acid-proof protective gloves.
f The donor battery and the machine's battery must have the same voltage
(12 V).
f Avoid short circuit due to voltage reversal (positive to positive, negative to
negative).
f Follow the booster cable connection sequence.
