Safety Guidelines
Charger Location
5.1 Locate the charger as far away from the battery as the
charger cables permit.
5.2 Never place the charger directly above the battery be-
ing charged; gases from the battery will corrode and
damage the charger.
5.3 Never allow battery acid to drip on the charger when
taking gravity readings or filling a battery.
5.4 Operate the charger only in a well-ventilated area that is
free of dangerous vapors.
5.5 Store the charger in safe, dry location and maintain it in
perfect condition.
5.6 Do not set the battery on top of the charger or where its
acid might drip onto the charger.
DC Connection Precautions
6.1 All switches should be set in the OFF position and AC cord
should be DISCONNECTED from electrical outlet before
you connect and disconnect the charger clamps. Never al-
low the clamps to touch each other.
6.2 When attaching the charger clamps, be certain to make
the best possible mechanical as well as electrical con-
nection. This will tend to prevent the clamps from slip-
ping off the connections, avoid dangerous sparking, and
assure safer and more efficient charging. The clamps
should be kept clean.
Hazardous voltage.
Can cause death or serious
personal injury.
Setting the switches to “OFF” does not always
disconnect the charger electrical circuit from
the AC power cord or the DC charger clamps.
Installing the Battery
Risk of explosive gases.
A spark near the battery may cause a battery explosion.
Follow these steps when the battery is installed in the
vehicle to reduce the risk of explosion.
7.1 Before working on the vehicle, firmly apply the emer-
gency brake and place the gear shift to NEUTRAL—shift
an automatic transmission to PARK.
7.2 Locate the charger as far away from the battery as the
charger cords permit and position the AC and DC cords
to avoid stepping on or tripping over them and to pre-
vent damage by hood, doors, or moving engine parts.
7.3 Stay clear of fan blades, belts, pulleys, and any other
parts that can cause physical injury.
7.4 Turn OFF all vehicle loads, including door lights, and
correct any defects in the vehicle’s electrical system that
may have caused low battery.
7.5 Check the polarity of the battery posts. The POSITIVE
(POS., P, +) post usually has a larger diameter than the
NEGATIVE (NEG., N,–) post.
7.6 Determine which post of the battery is grounded (con-
nected) to the chassis. If the negative post is grounded (as
in most vehicles), see paragraph 7.7. If the positive post is
grounded, see paragraph 7.8.
7.7 For a negative-grounded vehicle, first connect the
POSITIVE (RED) clamp from the charger to the POSI-
TIVE (POS., P, +) ungrounded post of the battery. Then
connect the NEGATIVE (BLACK) clamp to the NEGA-
TIVE (NEG., N,–) post of the battery. Do not connect the
clamp to the carburetor, fuel lines, or sheet-metal body
parts. When disconnecting the charger, turn all switches
to OFF, disconnect the AC cord, remove the clamp from
the NEGATIVE battery terminal, and then remove the
clamp from the POSITIVE battery terminal.
