Battery Service
New Battery Preparation
1. Remove the battery from the carton.
2. Place the battery in a well ventilated area on a level
non-concrete surface.
3. Test the battery. Refer to the Section entitled “Battery
Testing”. If the battery needs charging, charge the
battery. Refer to the Section entitled “Battery Charging”.
4. Connect the positive (+) lead (red) first, from the battery
harness to the positive terminal (+) on the battery using
the bolt and nut plate supplied with the battery. Connect
the negative (-) lead (black) last, to the negative terminal
(-) on the battery using the bolt and nut plate. Apply a
small amount of grease over the terminals to prevent
corrosion.
NOTE: The battery may come with the harness already
connected. If so, simply check to be sure the terminal
hardware is securely tightened.
5. Install the battery onto the power unit.
6. Plug the main harness connector
(A, Figure 24)

Battery Service
1. Test the battery. Refer to the Section entitled “Battery
Testing”. If the battery needs charging, charge the
battery. Refer to the Section entitled “Battery Charging”.
3. If the battery will not accept a charge or is partially
charged after charging per instructions, replace with a
new battery.
Battery Storage
If the mower is to be stored out of season on its rear
bumper, it is recommended the battery be removed, charged
and stored.
1. Remove the battery.
2. Perform battery service. Refer to the Section entitled
“Battery Service”.
3. Store the battery in an area away from the mower on a
wood surface.
NOTE: Do not store the battery on a concrete surface.
Battery Testing
Check the battery’s state of charge using a voltmeter.
Remember to hook the positive lead to the battery’s positive
terminal, and the negative lead to the negative terminal.
Check the reading against the chart below. If the voltage
reads less than 12.80 volts, charge the battery. Refer to the
Section entitled “Battery Charging”.
Battery Charging
To charge the battery:
1. With the supplied DC charger: Plug the charger
connector into the battery harness connector
(B, Figure
24)
. Plug the charger into a wall outlet and charge the
battery for 48 hours. (Longer periods will not damage
the battery.)
2. With an automotive-type charger: Connect the battery
charger to the battery terminals
(C)
; RED to the positive
(+) and BLACK to the negative (-) terminal. Slow charge
the battery at 0.4 amps for 5-10 hours. For a quick
charge, charge the battery at 4.0 amps for 30 minutes.
WARNING
DO NOT attempt any maintenance, adjustments or service
with engine and blade running. STOP engine and blade.
Disconnect spark plug wire and secure away from spark
plug. Engine and components are HOT. Avoid serious
burns, allow sufficient time for all components to cool.

WARNING
Shield the positive terminal with terminal cover located on
battery harness. This prevents metal from touching the
positive terminal, which could cause sparks.
