Maintenance
CAUTION
If the ignition is in the "ON" position there
is potential for sparks and engagement of
components. Sparks could cause an explosion or
moving parts could accidentally engage causing
personal injury.
Be sure ignition switch is in the "OFF" position
before charging the battery.
1. Park machine on level ground, disengage the blade
control switch, engage the parking brake, stop
engine, and remove key. Wait for all moving parts
to stop before leaving the operator's position.
2. Raise the seat.
3. Disconnect the negative (black) ground cable
from the battery post (Figure 54). Retain all
fasteners.

WARNING
Incorrect battery cable routing could damage
the machine and cables causing sparks.
Sparks can cause the battery gasses to
explode, resulting in personal injury.
• Always disconnect the negative (black)
battery cable before disconnecting the
positive (red) cable.
• Always connect the positive (red) battery
cable before connecting the negative
(black) cable.
4. Slide the rubber cover up the positive (red) cable.
Disconnect the positive (red) cable from the
battery post. Retain all fasteners.
5. Remove the battery strap (Figure 54) and lift the
battery from the battery tray.
Checking the Battery Charge
1. Remove the battery from the chassis; refer to
Removing the Battery.
2. 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
batteries in storage when the open circuit voltage
drops to 12.4 volts.
Note: To prevent damage due to freezing,
battery should be fully charged before putting
away for winter storage.
3. Check the voltage of the battery with a digital
g009783
voltmeter. Locate the voltage reading of the
battery in the table below and charge the battery
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 battery
cable is disconnected 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 (see chart below for recommended
charger settings).
