Section 7
Lead-acid batteries produce flammable and
explosive gases. To avoid personal injury
when checking, testing or charging
batteries, DO NOT use smoking materials
near batteries. Keep arcs, sparks and flames
away from batteries. Provide proper
ventilation and wear safety glasses.
WARNING:
WARNING:
Battery posts, terminals, and related acces-
sories contain lead and lead compounds,
chemicals known to the State of California
to cause cancer and reproductive harm.
Wash hands after handling.
7.7 BATTERY
Electric storage battery fluid contains sulfuric
acid which is POISON and can cause SEVERE
CHEMICAL BURNS. Avoid contact of fluid
with eyes, skin, or clothing. Use proper
protective gear when handling batteries. DO
NOT tip any battery beyond 45° angle in any
direction. If fluid contact does occur, follow
first aid suggestions below.
BATTERY ELECTROLYTE FIRST AID
EXTERNAL CONTACT — Flush with water.
EYES — Flush with water for at least 15
minutes and get medical attention
immediately.
INTERNAL — Drink large quantities of water.
Follow with Milk Of Magnesia, beaten egg,
or vegetable oil. Get medical attention
immediately. In case of internal contact, DO
NOT give fluids that would induce vomiting.
WARNING:
A. Charging the Battery
Refer to the battery charger’s manual for specific
instructions.
Under normal conditions the engine’s alternator will have
no problem keeping a charge on the battery. If the
battery has been completely discharged for a long period
of time, the alternator may not be able to recharge the
battery, and a battery charger will be required.
DO NOT charge a frozen battery. It may explode and
cause injury. Let the battery warm before attaching a
charger.
Whenever possible, remove the battery from the mower
before charging and make sure the electrolyte covers the
plates in all cells.
BATTERIES PRODUCE EXPLOSIVE GASES.
Charge the battery in a well ventilated space
so gases produced while charging can
dissipate.
WARNING:
Charging rates between 3 and 50 amperes are satisfactory
if excessive gassing or spewing of electrolyte does not occur
or the battery does not feel excessively hot (over 125°F).
If spewing or gassing occurs or the temperature exceeds
125°F, the charging rate must be reduced or temporarily
stopped to permit cooling.
B. Jump Starting
1. The booster battery must be a 12 volt type. If a vehicle
is used for jump starting, it must have a negative ground
system.
2. When connecting the jumper cables, connect the
positive cable to the positive battery post, then connect
the negative cable to the negative battery post.
