Charging Battery
WARNING: The battery contains corrosive fluid
and toxic material; handle with care and keep away
from children. Do not puncture, disassemble,
mutilate or incinerate the battery. Explosive gases
could be vented during charging or discharging. Use
in a well ventilated area, away from sources of
ignition.
NOTE: The special designed plug on the charger will only
fit into the plug on the battery box.
Plug the battery charger into the port on the underside of
the battery housing. See Fig. 7-4.
Insert the battery charger plug into a standard 120 volt
household outlet. Charge battery for 8 to 10 hours before
initial use. Do not charge longer than 1 hours. The
battery should only need to be charged upon initial setup
and after any other extended periods of non-use.
After charging, disconnect charger plug from outlet first,
then disconnect charger lead from battery.
IMPORTANT: Always plug charger lead into battery pack
lead first, and then insert battery charger plug into 120
volt standard household outlet. Follow this order of action
every time you charge the battery.
WARNING: Use only the battery charger supplied
with this mower.
