4. do not operate the Battery Charger in a closed-in area, or restrict ventilation in any

DC Connection Precautions:
1. Connect and disconnect dC output clamps only after removing the AC power cord
from the electrical outlet.
2. Never allow the dC output clamps to touch each other.
3. Attach the dC output clamps to the battery posts and twist or rock the clamps back
and forth several times to make a good connection. This helps keep the clamps from
slipping off the terminals, and helps to reduce the risk of sparking.
To Reduce Risk Of Sparking - When The Battery Is In The Vehicle:
1. Carefully position the AC input and dC output cords to reduce the risk of damage by
hood, door, or moving engine parts.
2. Stay clear of fan blades, belts, pulleys, and other moving parts that can cause
personal injury and/or property damage.
3. Check the polarity of the battery posts. A POSITIVE (+) battery post usually has a
larger diameter than a NEGATIVE (–) battery post.
4. To reduce explosion risk, never connect both Battery Charger dC output clamps
directly to the battery.
