Batteries, charging
WARNING! Explosion risk. During charging
oxyhydrogen gas is formed. Short-circuits, open
flame or sparks can cause a powerful explosion.
Ventilate well.
WARNING! Battery electrolyte is strongly
corrosive. Protect eyes, skin and clothing.
Always use safety glasses and gloves. In case
of skin contact, wash with soap and large
quantities of water. In case of eye contact rinse
immediately with large quantities of water and
contact a doctor as soon as possible.
Charge batteries if they have become discharged. If
the engine is not used for an extended period the bat-
teries should be fully charged initially and receive peri-
odic maintenance charging (see the battery manufac-
turers recommendations). A discharged state
damages batteries and they can also freeze and break
during cold weather.
IMPORTANT! Carefully follow all instructions for
the battery charger. To avoid risk for
electrochemical corrosion when using an external
charger when an external charger is used the
battery cables should be removed from the
battery before the charger is connected.
During charging the cell plugs should be unscrewed
but remain in the plugholes. Ventilate well, especially
if the battery is being charged in an enclosed space.
WARNING! Always turn off the charger before
loosening the charging clamps. Never confuse
the + and - poles of the batteries. Risk of
causing sparks and explosion.
There are special instructions for so-called quick-
charging. Quick-charging can shorten the useful life
of the battery and should therefore be avoided.
