Batteries, charging
WARNING! Explosion risk! Hydrogen is given off
when batteries are charged. This forms an explo-
sive mixture with air. A short circuit, open flame
or spark could cause a violent explosion. Venti-
late well.
WARNING! Battery electrolyte is highly corro-
sive. Protect your eyes, skin and clothes. Al-
ways use protective goggles and gloves. If acid
comes into contact with your skin, wash at once
with soap and a lot of water. If you get battery
acid in your eyes, flush at once with a lot of cold
water, and get medical assistance at once.
Charge batteries if they have become discharged. If
the engine is not used for a longer period of time, the
batteries should be fully charged, then possibly trickle
charged (please refer to the battery manufacturer’s
recommendations). Batteries are damaged by being
left discharged, and can also freeze and burst easier
in cold weather.
IMPORTANT! Observe the instruction manual for
the battery charger carefully. To avoid the risk of
electrochemical corrosion when an external
charger is connected, the battery cables should
be removed from the batteries before the charger
is connected.
During charging, unscrew the cell plugs but leave
them in the plug holes. Ventilate well, especially if the
batteries are charged in an enclosed space.
WARNING! Always switch off the charge current
before undoing the charging clamps. Never con-
fuse the positive (+) and negative (-) poles on the
batteries. This can cause serious arcing and can
cause an explosion.
Special instructions apply to so-called quick charg-
ing. Quick charging can shorten battery life, and
should therefore be avoided.
