9.1 SAFETY__________________________________________________________________
Batteries contain dilute sulfuric acid which can result in severe burns.
Hydrogen gas is formed within a battery during the charging cycle. Hydrogen in concentrations of 4% and higher are
explosive and can be ignited by open flame or an electrical spark. A battery explosion will cause sulfuric acid and
battery components to be thrown over a large area with considerable force.
Always observe the following warnings when working on or near batteries:
9.2
GENERAL ________________________________________________________________
The batteries used it this mower are sealed lead acid
(SLA) maintenance free type.
Temperature is important when conducting tests on a
battery and test results must be corrected to compensate
for temperature differences.
As a battery ages, it still performs adequately except that
its
capacity
is diminished. Capacity describes the time
that a battery can continue to provide its design amperes
from a full charge.
A new battery must
mature
before it will develop its
maximum capacity. A battery has a maximum life,
therefore good maintenance is designed to maximize the
available
life and reduce the factors that can reduce the
life of the battery.
WARNING
The electrolyte in a storage battery
is a dilute acid which can cause
severe burns to the skin and eyes.
Treat all electrolyte spills to the body
and eyes with extended flushing
with clear water. Contact a
physician immediately. Always wear
a safety shield or approved safety goggles when
charging batteries.
Hydrogen is explosive in concentrations as low as 4%
and is generated in the charging cycle of electric
mowers. Because it is lighter than air, it will collect in
the ceiling of buildings necessitating proper
ventilation. Air exchanges of 5 changes per hour is
considered the minimum requirement.
Never smoke around batteries.
Never charge batteries in an area that has open flame
or electrical equipment that could cause an electrical
arc.
Be sure that the key switch is off, all electrical
accessories are turned off and power connector is
disconnected before starting work on vehicle.
Remove all jewelry (watches, ring etc.)

WARNING
Wrap wrenches with vinyl tape to
prevent the possibility of a dropped
wrench from ‘shorting out’ a battery,
which could result in an explosion and
severe personal injury.
Electrolyte spills should be neutralized
with a solution of 1/4 cup (59.1ml) of
sodium bicarbonate (baking soda) dissolved in 1-1/2
gallons (5.7 liters) of water and flushed with water.
Never disconnect a circuit under load at a battery
terminal.
Wear appropriate protective clothing when working
with batteries. Electrolyte can cause severe burns to
the eyes, skin and clothing.
Full battery packs weigh approximately 55 lbs. Use
proper lifting techniques when moving them.
Batteries, 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 your hands
after handling.
