Servicing the Battery
WARNING
CALIFORNIA
Proposition 65 Warning
Battery posts, terminals, and related
accessories contain lead and lead compounds,
chemicals known to the State of California
to cause cancer and reproductive harm.
Wash hands after handling.
Important: The machine is shipped with a filled
lead acid battery.
DANGER
Charging or jump starting the battery may produce
explosive gases. Battery gases can explode causing
serious injury.
• Keep sparks, flames, or cigarettes away from
battery.
• Ventilate when charging or using battery in an
enclosed space.
• Make sure venting path of battery is always open
once battery is filled with acid.
• Always shield eyes and face from battery.
DANGER
Battery electrolyte contains sulfuric acid, which is
poisonous and can cause severe burns. Swallowing
electrolyte can be fatal or if it touches skin can
cause severe burns.
• Wear safety glasses to shield eyes, and rubber
gloves to protect skin and clothing when
handling electrolyte.
• Do Not swallow electrolyte.
• In the event of an accident, flush with water and
call a doctor immediately.
1. Check the voltage of the battery with a digital
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 should have
an output of 16 volts and 7 amps or less to
avoid damaging the battery (see chart for
recommended charger settings). This is
especially important on Kohler EFI (Electronic
Fuel Injection) units. Failure to do so may
damage the ECU (Electronic Control Unit).
Voltage Percent
Reading Charge
12.6 or 100%
greater
12.4 – 12.6 75–100%
12.2 – 12.4 50–75%
12.0–12.2 25–50%
11.7–12.0 0–25%
11.7 or less 0%
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.
2. Connect the negative battery cable.
Note: If the positive cable is also disconnected,
connect the positive (red) cable to the positive
battery terminal first, then the negative (black) cable
to the negative battery terminal. Slip insulator boot
over the positive terminal.
Note: If time does not permit charging the battery,
or if charging equipment is not available, connect
the negative battery cable and run the vehicle
continuously for 20 to 30 minutes to sufficiently
charge the battery.
Servicing the Hydraulic Oil
The machine is shipped with hydraulic oil in the
reservoir.
