Maintenance
Battery recharging
By battery charger
Your vehicle has a maintenance-free,
calcium-based battery.
• If the battery becomes discharged
in a short time (because, for exam-
ple, the headlights or interior lights
were left on while the vehicle was
not in use), recharge it by slow
charging (trickle) for 10 hours.
• If the battery gradually discharges
because of high electric load while
the vehicle is being used, recharge
it at 20-30A for two hours.
Always follow these instructions
when recharging your vehicle’s
battery to avoid the risk of SERI-
OUS INJURY or DEATH from
explosions or acid burns:
•
Before performing mainte-
nance or recharging the bat-
tery, turn off all accessories
and place the POWER button
to the OFF position.
•
Keep all flames, sparks, or
smoking materials away from
the battery.
•
Always work outdoors or in an
area with plenty of ventilation.
•
Wear eye protection when
checking the battery during
charging.
•
The battery must be removed
from the vehicle and placed in
a well ventilated area.
