Safety Guidelines
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 to the
battery. Never allow the clamps to touch each other.
6.2 When connecting the charger clamps to the battery, be
certain to make the best possible mechanical as well
as electrical connection. This will tend to prevent the
clamps from slipping off the connections, avoid danger-
ous sparking, and assure safer and more efficient charg-
ing. 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.

7.8 For positive-grounded vehicle, connect the
NEGATIVE
(BLACK)
clamp from the charger to the
NEGATIVE
(NEG., N, –)
ungrounded post of battery. Then connect
the
POSITIVE (RED)
clamp to the
POSITIVE (POS., P, +)
post of the battery. Do not connect clamp to carburetor,
fuel lines, or sheet-metal body parts.
When disconnecting the charger, turn the switches to
OFF
, disconnect the AC cord, remove the clamp from
the
POSITIVE
battery terminal, and then remove the
clamp from the
NEGATIVE
battery terminal.
CAUTION: WHEN POSITIVE (+) POST OF VEHICLE
BATTERY IS GROUNDED, DOUBLE CHECK POLARITY.
Removing the Battery
8. If it is necessary to remove the battery from the vehicle
or equipment, always remove the grounded terminal
from the battery first.
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.
Risk of explosive gases.
Make sure all vehicle loads are
OFF
to prevent a
possible arc..
8.1 Check the polarity of battery posts.
POSITIVE (POS.,
P, +)
post usually has larger diameter than
NEGATIVE
(NEG., N, –)
post.
8.2 Attach at least a 60 cm (24-inch), 6-gauge insulated bat-
tery cable to the negative (–) battery terminal.
8.3 Connect the
POSITIVE (RED)
charger clamp to the
POS-
ITIVE (POS., P, +)
post of battery.
8.4 Position yourself and the free end of cable as far away
from the battery as possible—do not face the battery
when making the final connection—then connect the
NEGATIVE (BLACK)
charger clamp to the free end of
the cable.
8.5 When disconnecting the charger, always do so in the re-
verse sequence of the connecting procedure; break the
first connection while staying as far away from the bat-
tery as practical.
Safety Reminder
For safe, efficient, and accurate charging and testing, review
the safety and operating instructions in this manual before
using the analyzer. In addition, follow all manufacturers’
instructions and BCI (Battery Council International) safety
recommendations.
Safety Precautions
Inspect the battery for damages and check the electrolyte
level. If the electrolyte level is too low, replenish it and
fully charge the battery. Always use the necessary safety
precautions when working with batteries to prevent severe
injury or death. Follow all manufacturers’ instructions and
BCI (Battery Council International) safety recommendations.
Battery acid is highly corrosive. If acid enters your eyes,
immediately flush them thoroughly with cold running
water for at least 15 minutes and seek medical atten-
tion. If battery acid gets on your skin or clothing, wash
immediately with a mixture of water and baking soda.
Always wear your PPE: proper gloves, rubber apron,
safety glasses or face shield when working with or
around batteries.
Keep hair, hands, and clothing as well as the analyzer
cords and cables away from moving engine parts.
Remove any jewelry or watches before you start servic-
ing the battery.
Use caution when working with metallic tools to pre-
vent sparks or short circuits.
Never lean over a battery when testing, charging, or
jump starting.
Never charge a frozen battery. Gases may form, cracking
the case, and spray out battery acid.
