DC CONNECTION PRECAUTIONS

Note: Steps to be done in a well-ventilated area away from 
aircraft.   
a.  Connect and disconnect DC output clips from battery only 
after removing charger power cord from outlet.
b.  Attach clips to battery posts and twist or rock back and forth 
several times to make good contact. This tends to keep clips 
from slipping off terminals and reduces risk of sparking.
