or being charged. Keep open flames and sparks
away from the battery 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 and a machine with the booster
battery on a dry 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
