	Charging
3	Connect battery charger	Do not reverse polarity and only use fully-insulated terminal clamps, risk of short circuit! Pay attention to the correct installation position of the vent hose and stop plugs otherwise battery acid which runs out will damage the vehicle. Use charger with at least 30 A charging current due to the high current requirement. Always clip the ground terminal (1) of the charger onto the negative terminal of the starter battery (G1/4). When charging the on-board electrical system battery always clip the positive terminal (2) of the charger onto the charge support point (5).
4	Charge starter battery (G1/4) or on-board electrical system battery	Discharged absorbent glass mat batteries which have a voltage below 7 V are not "detected" according to charger model, therefore here, before charging, a second charged battery (with 12 V rated voltage) must be clipped on in parallel to the absorbent glass mat battery. Normal charging: Charging current max. 10 % of battery capacity: e.g. max. 10 A charging current for a 100 Ah battery. Rapid charging: charging current max. 50 % of battery capacity for 30 min: e.g. max. 50 A charging current for a 100 Ah battery.
5	Disconnect battery charger	Always switch off charger beforehand in order to prevent arcing.
