Warning: Explosive gases are emitted when batteries charge. Avoid flames or
sparking. Disconnect the charger from the mains before you connect the
battery. Battery acid is extremely caustic. Avoid any contact with skin or
clothing. Immediately wash with soap and water in the case of unintentional
contact.
Warning: Never charge Li-ion or other battery technologies with this charger.
This can cause serious damage to the device or start a fire. Only use for
rechargeable lead batteries in wet, AGM, or gel technology. Never place the
charger on the battery during the charging process.
Never place the charger under water, make sure that no liquids penetrate it.
Caution: With wet batteries, before connecting the charger, the acid level must
be checked. If needed, top up lead acid batteries with distilled water:
Maintenance-free batteries (gel or AGM) should not be topped off with distilled
water. This is not permitted. Avoid short circuits to the battery poles. Do not
place tools or metallic objects on the battery – this can lead to short circuits and
fires. The device may only be repaired by technicians who are familiar with the
relevant safety regulations and instructions. Do not load the electrical and
charging cables through unnecessary pulling or jamming/clamping. The device
may not be operated with a damaged connection cable. Do not operate the
device in the proximity of easily flammable materials. The device heats up
during operation. Do not place the charger on flammable or sensitive surfaces.
There is a risk of fire or a risk of damaging surfaces, e.g. of seats or painted
surfaces.
Caution: The charger cable for connection to the motorcycle may not be
lengthened. Only use the charging adapter provided on the battery poles.
Caution: Do not expose the charger to excessive heat; avoid mechanical impact
caused by dropping or falling. Avoid damage or use of force on the operating
keys, e.g. with tools or objects.
