Sears 28.71225 Automobile Battery Charger User Manual


 
3
Read, understand and follow all instructions for the charger, battery, vehicle and any 3.5
equipment used near the battery and charger. Study all of the battery manufacturer’s
specic precautions while charging and recommended rates of charge.
Determine the voltage of the battery by referring to the vehicle owner’s manual and 3.6
make sure that the output voltage selector switch is set to the correct voltage. If the
charger has an adjustable charge rate, charge the battery in the lowest rate rst.
Make sure that the charger cable clips make tight connections.3.7
CHARGER LOCATION4.
RISK OF EXPLOSION AND CONTACT WITH
BATTERY ACID.
Locate the charger as far away from the 4.1
battery as the DC cables permit.
Never place the charger directly above 4.2
the battery being charged; gases from the
battery will corrode and damage the charger.
Do not set the battery on top of the charger.4.3
Never allow battery acid to drip onto the charger when reading the electrolyte specic 4.4
gravity or lling the battery.
Do not operate the charger in a closed-in area or restrict the ventilation in any way.4.5
DC CONNECTION PRECAUTIONS5.
Connect and disconnect the DC output clips only after setting all of the charger switches 5.1
to the “off” position (if applicable) and removing the AC plug from the electrical outlet.
Never allow the clips to touch each other.
Attach the clips to the battery and chassis, as indicated in sections 6 and 7.5.2
FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN VEHICLE6.
A SPARK NEAR THE BATTERY MAY CAUSE
A BATTERY EXPLOSION. TO REDUCE THE
RISK OF A SPARK NEAR THE BATTERY:
Position the AC and DC cables to 6.1
reduce the risk of damage by the hood, door
and moving or hot engine parts. NOTE: If it is
necessary to close the hood during the charging process, ensure that the hood does not
touch the metal part of the battery clips or cut the insulation of the cables.
Stay clear of fan blades, belts, pulleys and other parts that can cause injury.6.2
Check the polarity of the battery posts. The POSITIVE (POS, P, +) battery post usually 6.3
has a larger diameter than the NEGATIVE (NEG, N, -) post.
Determine which post of the battery is 6.4
grounded (connected) to the chassis (vehicle
frame). If the negative post is grounded to
the chassis (as in most vehicles), see step
6.5. If the positive post is grounded to the
chassis, see step 6.6.
For a negative-grounded vehicle, connect 6.5
the POSITIVE (RED) clip from the battery
charger to the POSITIVE (POS, P, +)
ungrounded post of the battery. Connect
the NEGATIVE (BLACK) clip to the vehicle
frame or engine block at a distance away
from the battery. Do not connect the clip to
the carburetor, fuel lines or sheet-metal body
parts. Connect to a heavy gauge metal part
of the vehicle frame or engine block.
