stepped on, tripped over, or otherwise subjected
to damage or stress.

8.

An extension cord should not be used unless
absolutely necessary.
Use of improper extension cord could result in a
risk of fire and electric shock. If extension cord
must be used make sure:
a） That blades of extension cord are the same

number, size, and shape as those of plug

on battery charger;

b） That extension cord is properly wired and in

good electrical condition;

c） That wire size is large enough for AC

ampere

rating of battery charger as specified in table 1.

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:

2,200 watts/220volt=10 Amperes

9.

Do not operate battery charger with damaged

cord or plug ，should 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.
