MAINTENANCE
Battery
If the battery is too weak to start the engine, it
must be recharged.
Jumper Cable Use
1. Connect each end of the RED cable to the
POSITIVE (+) terminal on each battery, taking
care not to short against chassis.
2. Connect one end of the BLACK cable to the
NEGATIVE (-) terminal of the fully charged
battery.
3. Connect the other end of the BLACK cable
to a good CHASSIS GROUND on the mower
with the discharged battery, away from the
fuel tank and battery.
To remove cables, reverse order
1. Remove BLACK cable first from chassis and
then from the fully charged battery.
2. Remove RED cable last from both batteries.
The mower has a maintenance free battery
and does not need servicing. However, periodic
charging of the battery with an automotive type
battery charger will extend its life.
• Keep battery and terminals clean.
• Keep battery bolts tight.
• See chart for charging times.
