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 POSI-
TIVE (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.

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.
WARNING: 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.

cable to the negative (–) battery terminal.
8.3 Connect the POSITIVE (RED) charger clamp to the POSI-
TIVE (POS., P, +) post of battery.

the battery as possible—do not face the battery when
making the final connection—then connect the NEGA-
TIVE (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 battery
as practical.
