If the input rating of a battery charger is given in
watts rather than in amperes, the corresponding
ampere rating is to be determined by dividing the
wattage rating by the voltage rating–for example:
1,250 watts
125 volts
= 10 amperes
9.
Do not operate battery charger with damaged cord
or plug-replace them immediately.
10. Do not operate battery charger if it has received a
sharp blow, been dropped, or otherwise damaged
in any way; take it to a qualified serviceman.
11. Do not disassemble battery charger; take it to a
qualified serviceman when service or repair is
required. Incorrect reassembly may result in a risk
of electric shock or fire.
12. To reduce risk of electric shock, unplug charger
from receptacle before attempting any
maintenance or cleaning. Removing the battery
will not reduce this risk.
