Batteries. Charging
WARNING! Risk for explosion. Charging gener-
ates hydrogen gas (oxyhydrogen gas). A short
circuit, naked flam or spark can cause a power-
ful explosion. Ventilate well.
WARNING! Battery electrolyte is extremely cor-
rosive. Protect eyes, skin and clothes. Always
use protective goggles and gloves. In case of
splashes on the skin, wash with soap and plenty
of water. In case of splashes in the eyes, rinse
immediately with plenty of water and call a doc-
tor.
Charge the batteries if they have been discharged. If
the boat is not to be used for a long time, the batter-
ies must be fully charged and then trickle-charged
(refer to battery manufacturer's recommendations).
The batteries will be harmed if left discharged and
can also freeze and crack in cold weather.
IMPORTANT! Follow the battery charger user
instructions carefully. Disconnect the battery ca-
bles before connecting the battery charger to
avoid electrochemical corrosion when using an
external battery charger.
The battery plugs must be unscrewed but left in the
holes while charging is in progress. Ventilate well, es-
pecially if batteries are being charged in confined
spaces.
WARNING! Always cut the charging current be-
fore disconnecting the charger cables. Never re-
verse the polarity of the battery. Risk of sparks
and explosion.
Special directions apply for rapid charging. Rapid
charging can impair the service life of the batteries
and should be avoided.
Electric welding
Disconnect the positive and negative battery cables.
Then disconnect all the leads to the generator.
Always connect the weld clamp to the component be-
ing welded and as close to the welding point as possi-
ble. Never connect the clamp to the engine or in such
a way as current can pass across a bearing.
IMPORTANT! When welding has ceased, con-
nect the leads to the generator before recon-
necting the battery cables.
