Maintenance: Electrical system
Batteries. Maintenance
WARNING! Risk for fire and explosion. Never ex-
pose the battery to naked flames or sparks.
WARNING! Never reverse the polarity of the bat-
tery. Risk of sparks and explosion.
WARNING! Battery electrolyte is extremely cor-
rosive. Protect eyes, skin and clothes when han-
dling batteries. 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 doctor.
Connecting and disconnecting
Connect the (+) cable (red) to the (+) terminal of the
battery first. Then connect the (–) cable (black) to the
(–) pole of the battery.
Disconnect the (–) cable (black) first and then the (+)
cable (red).
Cleaning
Keep batteries dry and clean. Contaminants and ox-
ide on batteries and battery terminals can cause
short-circuits, voltage drops and discharging, espe-
cially in damp weather. Clean oxide from battery ter-
minals and cable shoes with a brass brush. Tighten
cable shoes well and grease them with terminal
grease or petroleum jelly.
Electrolyte level
The electrolyte should be 5–10 mm (0.2–0.4") above
the cell plates in the battery. If necessary, top up with
distilled water. After topping up, the batteries should
be charged by connecting to a battery charger, or by
running the engine at normal speed for 30 minutes.
NOTE! Special instructions must be followed for cer-
tain maintenance-free batteries.
