Battery Care
Always recycle batteries in accordance with local laws
and regulations. Contact your local solid waste collection
site or recycling facility to obtain information on local
recycling processes. For more information on battery
recycling, visit the Battery Council International website
at: http://batterycouncil.org
Proper care can extend battery life. Follow the recommen-
dations below for best performance and long battery life.
• Do not allow the battery to fully discharge. Charge
the battery every 4–6 weeks if the unit is not being
used. Operate the engine for at least 45 minutes to
maintain proper charge.
• Do not charge a fully charged battery. Heat from
the trickle charger could damage the battery. The
battery will read 12–13.2 volts when fully charged.
• Do not crank engine when battery charge is low.
• Before charging the battery, examine its external
appearance. Never charge or use a battery that
shows cracks, changes shape, leaks, or is other-
wise damaged.
• Store an unused battery in a dry environment with
temperatures between +40°F (5°C) and +95°F
(+35°C).
Charging Battery
If the battery loses charge, use a trickle charger to
charge it. The charger must have an output of 14.4-15
volts at no more than 0.69 amps.
NOTE: The charging system of a running engine is
designed to maintain a battery’s present charge. Starting
a machine that has been significantly discharged, or is
dead, using the recoil starter or jumper cables will not
recharge the battery.
Proceed as follows to connect the battery to a charger.
1. Disconnect battery cables.
2. Connect the negative (black) battery charger cable
to the battery negative (-) terminal, and connect the
positive (red) battery charger cable to the battery
positive (+) terminal.
3. Plug the battery charger into an outlet.
4. Charge until battery charger indicates battery is fully
charged. Typical battery charge times range from
six to eight hours depending on level of discharge.
Do not charge battery for more than 24 hours.
5. Disconnect charger from outlet once battery has
charged.
6. Disconnect battery from charger and remove the
cables, removing the negative cable first.
