Charging the battery
Safety instructions when loading the battery
Risk of explosion from resulting gases during charging!
A mixture of oxygen and hydrogen (oxyhydrogen) is released by the
battery during charging. This gas mixture is highly explosive. Serious
injuries or even death can result if the gas ignites.
► The voltage and charging capacity of the battery charger must match
the battery. Use only battery chargers integrated by the machine
manufacturer into the machine.
► Check the cable and plug-and-socket connections for visible damage
before charging.
► Extension cables may be a maximum of 10 m (32.8 ft) long and must
be approved for a continuous operation with 16 A.
► Ventilate the room in which the battery is being charged.
► The surfaces of the battery cells must be free during the charging
process, in order to ensure sufficient ventilation.
► Do not smoke or use an open flame when working around the battery.
► There must be no flammable or sparking material, fluids and lubricants
within a distance of at least 2 m within the area of the machine parked
for charging.
► Do not perform any welding or grinding work in the area of the machine
parked for charging.
► Have flame retardants ready. In case of fire, extinguishing with water
can cause a reaction with the battery acid. Therefore, only use power a
powder extinguisher. Never extinguish burning batteries with water.
► Do not place any metallic objects on the battery.
► When charging, observe the notes for low temperatures
– see chapter 4 “Notes about low and high external temperatures” on
page 4-46.
► Follow the safety instructions of the battery and battery charger
manufacturer under all circumstances.
