• Disconnect mains supply before connecting or disconnecting the battery clamps.

• Never charge in vicinity of open ames or any equipment which may produce
sparks. A battery may produce explosive gases during charging and good ventila­tion should therefore be ensured if charging takes place indoor.

• The charger has to be placed on a solid surface with good ventilation.

• The charger may not be covered up or exposed to direct sunlight.

• The battery manufacturer’s advices have to be followed carefully.

• The charger can only be used for rechargeable lead/acid, GEL or AGM batteries.

• The charging cables can only be changed to other keepower cables.

• In case of damaged cables the charger cannot be used.

• Repair of the charger may only be done by an authorized shop.

• Place the charger in horizontal position to obtain the IP class.

• The charger is not intended for use by persons (including children) with reduced
physical, sensory or mental capabilities, or lack of experience and knowledge, un­less they have been given supervision or instruction concerning use of the charger
by a person responsible for their safety.
