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.
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.
For Kohler and Kawasaki machines: Check the
voltage of the battery with a digital voltmeter or with
the message display. If the ignition key is turned
to the "on" position for a few seconds, the battery
voltage will be displayed in the area where the hours
are normally displayed. Locate the voltage reading of
the battery in the table 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).
For Briggs EFI machines: Check the voltage of the
battery with a digital voltmeter or with the message
display. When the ignition is set to accessory mode,
the module will display the battery voltage. If the
voltage is less than 12.4 volts, the battery may need
to be charged.
Important: In order to prevent damage to the
battery, use an automatic 12 volt smart charger
approved for use with AGM type batteries with an
output of 3.5 amps or less. Exmark recommends
the use of battery charger P/N 135-7024. Make
sure the negative battery cable is disconnected
before charging and that the charger is set to the
correct mode for 12 volt AGM batteries.

Recommended Jump
Starting Procedure
Service Interval: As required
1.
Check the weak battery for terminal corrosion
(white, green, or blue "snow"), it must be cleaned
off prior to jump starting. Clean and tighten
connections as necessary.
