5. Do not abuse the cord. Never carry the charger by the cord or yank it to
disconnect it from the receptacle. Disconnect the charger by the plug rather
than the cord. Have the damaged or worn power cord and strain reliever
replaced immediately. DO NOT ATTEMPT TO REPAIR POWER CORD.
6. Make sure that the cord is located so that it will not be stepped on, tripped
over, or otherwise subjected to damage or stress.
7. Do not use an extension cord unless absolutely necessary. Use of an
improper extension cord could result in a risk of fire and/or electric shock. If
an extension cord must be used, make sure:
A. that the pins on plug of the extension cord are the same number, size
and shape as those of the plug on the charger.
B. that the extension cord is properly wired and in good electrical condition.
C. that the wire size of cord is at least as specified in following chart:
LENGTH OF CORD IN FEET
AWG SIZE OF CORD
D. An extension cord used outdoors must be marked with the suffix
A or W following the cord type designation. For example – SJTW-A
indicates that it is acceptable for outdoor use.

immediately to avoid a hazard. DO NOT ATTEMPT TO REPAIR A POWER
CORD.

or otherwise damaged in any way. Take it to a qualified serviceman.
10. Do not disassemble the charger or the battery pack. Take these items to
a qualified serviceman when service or repair is required. Incorrect re-
assembly may result in a risk of electric shock or fire.
11. Unplug the charger from the outlet before attempting any maintenance or
cleaning to reduce risk of electric shock.

19. Double insulated tools are equipped with a polarized plug (one blade is
wider than the other). This plug will fit in a polarized outlet only one way. If
the plug does not fit fully in the outlet, reverse the plug. If it still does not fit,
