-Do not interchange the positive and neg­
ative cables .
- When working on the battery , be sure
not to short-circuit the terminals with
tools or other metal objects. This would cause the battery to heat up very quickly,
which could lead to damage or explosion
and personal injury.
- When a battery is charged, it produces
hydrogen gas which is explosive and
could cause personal injury .
- Always keep the battery well out of the reach of children .
- Before work is done on the electrical sys­
tem, disconnect the negative ground ca ­
ble .
- Before performing any work on the elec ­
trical system , switch off the engine and
ignition as well as any electrical equip­
ment. The negative cable on the battery
must be disconnected. If you are just go­
ing to replace a light bulb, then it is
enough to switch off the lights.
- Before disconnecting the battery, switch
off the anti-theft alarm system! Other­
wise you will set off the alarm.
- When disconnecting the battery, first
disconnect the negative cable and then
the positive cable.
- Before reconnecting the battery, make
sure all electrical consumers are switch­
ed off. Reconnect the positive cable first
and then the negative cable. Never inter­
change the cables - this could start a fire!
- Never charge a fro zen or a thawed-out
battery. It could explode! If a battery has
fro zen, then it must be replaced. A dead
battery can freeze over at 32°F (O°C) .
- Make sure the vent hose is always attach­
ed to the opening on the side of the bat­
tery .
- Never use batteries which are damaged.
There is the danger of an explosion ! Al­
ways replace a damaged battery .

erwise it will be damaged and will then
have to be replaced.
