POTENTIAL HAZARD
·If the ignition is in the "ON" position, there is
potential for sparks and engagement of components.
WHAT CAN HAPPEN
·Sparks could cause an explosion or moving parts
could accidently engage causing personal injury.
HOW TO AVOID THE HAZARD
· Be sure ignition switch is in the "OFF" position
before charging the battery.
7.2 Connecting the negative battery cables:
Note: If the positive cable is also disconnected,
connect the positive (red) cable to the positive battery
terminal first, then the negative (black) cable to the
negative battery terminal. Slip insulator boot over the
positive terminal.
Note: If time does not permit charging the battery, or
if charging equipment is not available, connect the
negative battery cables and run the engine
continuously for 20 to 30 minutes to sufficiently
charge the battery.
·Battery contains sulfuric acid. Avoid contact and
always shield eyes, face, skin, and clothing from
battery. Cigarettes, flames, or sparks could cause
battery to explode.
·Do not charge or use booster cables or adjust post
connection without proper training.
·If battery acid comes in contact with skin or eyes,
then flush with water and call a physician
immediately.
·Keep out of reach of children.
7.3 Maintenance Period
Service Interval: Monthly
Allowing batteries to stand for an extended period
without recharging them will result in reduced
performance and service life. To preserve optimum
battery performance and life, recharge them in storage
when the open circuit voltage drops to 12 Volts.
Note: To prevent damage due to freezing, battery
should be fully charged before putting away for winter
storage.
a) Check the voltage of the battery with a digital
voltmeter. Locate the voltage reading of the battery in
the table (See chart 7.1.1 ) and charge the batter for
the recommended time interval to bring the charge up
to a full charge of 12.6 Volts or greater.
IMPORTANT: Make sure the negative & positive
battery cables are connected correctly and the battery
charger used for charging the battery has an output of
16 volts and 7 amps or less to avoid damaging the
battery.
