• Do not put objects into the cooling slots of the
battery charger.
• Do not connect the battery charger terminals to
metal objects as this can short circuit the battery
charger.
• Only use three-wire outdoor extension wires that
have three-prong grounding plugs and grounding
receptacles that accept the appliance's plug.
• Use a residual-current device (RCD) for increased
safety. A residual-current device is installed to
prevent injuries from an electrical fault.

extension wire applicable for outdoor operation. Use
of a wire applicable for outdoor operation decreases
the risk of electrical shock.

cracks in it.
• Examine extension wires regularly and replace them
if damaged.
