MAINTENANCE AND LUBRICATION 209
Jump-Starting Engine
If you encounter a situation in which it is necessary to jump-start an engine, use the
following procedures.
WARNING
Batteries which are to be linked together
must be of the same voltage (12 to 12, 24
to 24). Take care to observe proper polarity
when connecting batteries. Batteries
produce explosive gases. Keep sparks,
flames, cigarettes, etc., away from batteries
at all times. Protect your eyes by wearing
safety goggles. Be sure vehicles are NOT
touching each other.
CAUTION
To avoid damaging any electronic
controllers when jump-starting a V-MAC
vehicle, always turn the ignition switch
OFF before connecting the batteries.
1 Connect positive (+) cable to positive (+) post of discharged battery.
2 Connect the other end of the same cable to the positive (+) post of the booster battery.
3 Connect the second cable, negative (-) side, to the other post of the booster battery.
4 Make the final connection to the negative (-) battery terminal of the stalled vehicle,
and stand back.
5 Start the vehicle with the booster batteries and then start the stalled vehicle. Shut
down the vehicle with the booster batteries and remove the cables in the reverse order
of connection.
WARNING
Do NOT connect the final negative (-)
connection to the frame of the stalled
vehicle. This would cause all current to
flow through the master ground circuit
breaker resulting in overload.
