Maintenance
Caring for the Battery
Service Interval: Every 25 hours—Check the
electrolyte level. (If machine is in
storage, check every 30 days.)
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.
The battery electrolyte level must be properly maintained
and the top of the battery kept clean. If the machine is
stored in a location where temperatures are extremely
high, the battery will run down more rapidly than if
the machine is stored in a location where temperatures
are cool.
Maintain the cell level with distilled or demineralized
water. Do not fill the cells above the bottom of the split
ring inside each cell. Install the filler caps with the vents
pointing to the rear (toward the fuel tank).
Battery electrolyte contains sulfuric acid which
is a deadly poison and causes severe burns.
• Do not drink electrolyte and avoid contact
with skin, eyes or clothing. Wear safety
glasses to shield your eyes and rubber gloves
to protect your hands.
• Fill the battery where clean water is always
available for flushing the skin.
• Charge the battery in a well-ventilated place
so that the gasses produced while charging
can dissipate.
• Since the gases are explosive, keep open
flames and electrical sparks away from the
battery; do not smoke.
• Nausea may result if the gases are inhaled.
• Unplug the charger from the electrical outlet
before connecting to or disconnecting the
charger leads from the battery posts.
Keep the top of the battery clean by washing it
periodically with a brush dipped in ammonia or
bicarbonate of soda solution. Flush the top surface with
water after cleaning. Do not remove the filler caps while
cleaning.
The battery cables must be tight on the terminals to
provide good electrical contact.
Incorrect battery cable routing could damage
the tractor 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.
If corrosion occurs at the terminals, disconnect the
cables, negative (–) cable first, and scrape the clamps and
terminals separately. Connect the cables, positive (+)
cable first, and coat the terminals with petroleum jelly.
Important: Always disconnect the battery cables,
ground cable (–) first, to prevent possible wiring
