Electrical System Safety
•
Disconnect the battery before repairing the
machine. Disconnect the negative terminal first
and the positive last. Connect the positive terminal
first and the negative last.
•
Charge the battery in an open, well-ventilated
area, away from sparks and flames. Unplug the
charger before connecting or disconnecting the
battery. Wear protective clothing and use insulated
tools.
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.
Servicing the Battery
Service Interval:
Every 25 hours—Check the
electrolyte level (if machine is in
storage, check every 30 days).
Park the machine on a level surface, lower the cutting
units, engage the parking brake, shut off the engine,
and remove the key from the ignition switch.
Maintain the battery electrolyte level and keep the top
of the battery clean. Store the machine where the
temperature is cooler rather than warmer to prevent
the battery from discharging more rapidly.
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).
DANGER
Battery electrolyte contains sulfuric acid
which is fatal if consumed and causes severe
burns.
•
Do not drink electrolyte and avoid contact
with skin, eyes, or clothing. Wear eye
protection to shield your eyes and rubber
gloves to protect your hands.
•
Fill the battery where clean water is always
available for flushing the skin.
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.
WARNING
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.
Checking the Fuses
The fuses in the electrical system are located under
the control panel.
