1.8 To reduce the risk of electric shock, unplug the charger from
the outlet before attempting any maintenance or cleaning of the
battery or charger.
1.9 Examine the battery, charger and the connectors for excessive
wear or damage each time you charge the battery. If damage or
excessive wear is detected, do not use the charger or battery
until you have replaced the worn or damaged part. Do not use or
charge the battery with a damaged cord or connector. Never lift
or carry the battery by the wires or connector. This can damage
the battery and possibly cause an electric shock or fire resulting in
property damage or personal injury.
1.10 Make sure the battery charger connector makes a tight connection.
1.11 Do not use the battery if it has received a sharp blow, been dropped
or otherwise damaged in any way. Replace it immediately.

Replace it immediately.
1.13 Do not immerse the battery in water; wipe it clean with a damp
cloth only after disconnecting it from the vehicle or charger.
1.14 Do not short-circuit the battery. All Schumacher batteries have a
fuse protection in the wiring harness of the battery. In the event of a
short circuit, the fuse will blow. Do not bypass or modify the fuse or
it could result in an electric shock, fire or explosion. In the event of
a blown fuse, disconnect the battery from the vehicle and replace
the fuse with one of the same type and rating. Repair or replace the
cause of the short circuit before reconnecting the battery.
2. PERSONAL PRECAUTIONS
RISK OF EXPLOSIVE GASES. A SPARK NEAR THE
BATTERY MAY CAUSE A BATTERY EXPLOSION. TO
REDUCE THE RISK OF A SPARK NEAR THE BATTERY:
2.1 Working in the vicinity of a lead-acid battery is dangerous.
Batteries generate explosive gases during normal battery
operation. For this reason, it is of utmost importance that you
follow the instructions each time you charge, use, connect or
disconnect the battery.
2.2 NEVER smoke or allow a spark or flame in the vicinity of the battery.
2.3 Do not permit the battery to freeze. NEVER charge a frozen battery.
