G
Risk of poisoning from batteries containing lead!
Battery poles, terminals and parts inside the battery contain lead. Residue
containing lead ca
n stick to your hands and may not be allowed to enter
your body – e.g. by touching food.
Wash your hands after working on batteries.
G
Risk of explosion from escaping hydrogen!
Do not place tools on the battery and keep naked lights away from it.
G
Risk of explosion from static charge!
Use only antistatic cloths to clean the batteries.
This prevents the build-up of static charges which could cause hydrogen
mixtures to explode.
G
Risk of burns from battery acids!
Battery acid is highly caustic. Wear safety glasses and protective gloves. Do
not tilt the
battery. Rinse off or wash out any acid spray on the skin or cloth-
ing using soap suds.
S
Risk of damage to the crane's electrical system!
Always switch off the battery master switches before commencing work on
the truck crane's electrical sy
stem.
This prevents short circuits and resulting damage to the electrical system.
