A7. SPECIAL PROCEDURES
141
Jump Starting
Safety
WARNING
Procedure. If you are unsure how to follow this
procedure, we strongly recommend that you seek the
help of a competent mechanic.
Batteries contain sulfuric acid which is poisonous and
corrosive. Wear protective safety glasses when jump
starting and avoid spilling acid on your skin, clothing or
the vehicle.
Do not try to charge a frozen battery. If you try to
charge a frozen battery or jump start and run the
engine, the battery could explode.
Do not use the battery if the electrolyte is frozen. To
prevent the battery electrolyte from freezing, keep the
battery at full charge.
Do not smoke when checking the battery electrolyte
levels. Batteries give off a flammable gas that can
explode. When starting another machine, make sure
the two machines do not touch as this could cause
sparks. Sparks could ignite the battery gas. If this
happens the battery could explode.
Even with the starter switch set to the off position some
circuits will still be energized when the external power
supply is connected. Ensure all machine switches are
set to the off position before connecting the external
power supply.
Only use jump start cables that are in good condition
with securely attached connectors.
Connect both ends of one jump start cable before
connecting the other cable.
CAUTION:
Jump Start Supply. The jump start supply should not
be more than 12 volts. Using a higher voltage supply
will damage your machines electrical system. Do not
connect two batteries together to give 24 volts. This
could burn out the induction manifold heater and
damage the starter motor.
WARNING:
Electric Shock. Keep all metal straps and fasteners
from clothes or jewelry clear of the positive (+) battery
terminal. Such items can cause a short between the
battery terminal and nearby metal framework. If this
happens you could get burned.
