USING BOOSTER BATTERIES

CAUTION:
•
An explosive gas is produced while batteries
are in use or being charged. Keep flames or
sparks away from the battery area. Charge the
batteries in a well ventilated area.
Do not continue to use or charge the battery
when electrolyte level is lower than specified.
Explosion of the battery may result.
Park the machine on a dry, firm or concrete
surface, not on steel plates, if the machine is
parked on steel plates, dangerous sparks may
be unexpectedly created on the machine.
Never connect a positive terminal to a negative
terminal, as a dangerous short circuit will oc-
cur.
•
The operator must be in the operator's seat so
that the machine will be under control when
the engine starts. Jump starting is a
two-person operation.
