WARNING
Be careful when handling the battery. Avoid spilling
electrolyte. Keep flames and sparks away from the
battery.
When removing or installing battery cables, disconnect
the negative cable FIRST and reconnect it LAST. If not
done in this order, the positive terminal can be shorted to
the frame by a tool.
WARNING
Never store the unit (with fuel) in an enclosed, poorly
ventilated structure. Fuel vapors can travel to an
ignition source (such as a furnace, water heater, etc.)
and cause an explosion.
Fuel vapor is also toxic to humans and animals.
Battery Maintenance
Cleaning the Battery and Cables
1. Disconnect the cables from the battery, negative cable
first (B, Figure 34).
2. Clean the battery terminals and cable ends with a wire
brush until shiny.
3. Reinstall the battery and reattach the battery cables,
positive cable first (see A, Figure 34)
4. Coat the cable ends and battery terminals with petroleum
jelly or non-conducting grease.
Storage
Before you store your unit for the off-season, read the
Maintenance and Storage instructions in the Safety Rules
section, then perform the following steps:
• Disengage the PTO, set the parking brake, & remove the
key.
• Perform engine maintenance and storage measures
listed in the engine owner’s manual. This includes
draining the fuel system, or adding stabilizer to the fuel
(do not store a fueled unit in an enclosed structure - see
warning).
• Battery life will be increased if it is removed, put in a
cool, dry place and fully charged about once a month. If
the battery is left in the unit, disconnect the negative
cable.
Before starting the unit after it has been stored:
• Check all fluid levels. Check all maintenance items.
• Perform all recommended checks and procedures found
in the engine owner’s manual.
• Allow the engine to warm up for several minutes before
use.

Battery Charging
A dead battery or one too weak to start the engine may be
the result of a defect in the charging system or other
electrical component. If there is any doubt about the cause
of the problem, see your dealer. If you need to replace the
battery, follow the steps under Cleaning the Battery & Cables
in the Regular Maintenance Section.
To charge the battery, follow the instructions provided by the
battery charger manufacturer as well as all warnings
included in the safety rules sections of this book. Charge the
battery until fully charged. Do not charge at a rate higher
than 10 amps.
WARNING
Keep open flames and sparks away from the battery;
the gasses coming from it are highly explosive.
Ventilate the battery well during charging.
