Drive System Maintenance; Changing The Front Differential Oil (Four Wheel Drive Models Only); Inspecting The Constant Velocity Boot (Four Wheel Drive Models Only) - Toro workman HDX-D 07368 Operator's Manual

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.
• Keep battery electrolyte level properly maintained.
• 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 fill cap
while cleaning.
• Ensure that the battery cables are kept tight on the
terminals to provide good electrical contact.
• If corrosion occurs at terminals, remove the battery
cover, disconnect the cables (negative (–) cable first),
and scrape the clamps and terminals separately.
Reconnect the cables (positive (+) cable first) and
coat the terminals with petroleum jelly.
• Maintain cell electrolyte level with distilled or
demineralized water. Do not fill the cells above the
bottom of the fill ring inside each cell.
• If you store the machine 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.
