Charging Procedure - DeWalt DW970 Instruction Manual

• An extension cord must have adequate wire size (AWG or
American Wire Gauge) for safety. The smaller the gauge number of
the wire, the greater the capacity of the cable, that is 16 gauge has
more capacity than 18 gauge. When using more than one extension
to make up the total length, be sure each individual extension con-
tains at least the minimum wire size.

• The charger is ventilated through slots in the top and the bot-
tom of the housing. Do not place any object on top of charger or
place the charger on a soft surface that might block the ventilation
slots and result in excessive internal heat. Place the charger in a posi-
tion away from any heat source.

dropped, or otherwise damaged in any way; take it to an authorized
service center.

when service or repair is required. Incorrect reassembly may result in
a risk of electric shock, electrocution or fire.

reduce this risk.

trical power (120 Volts AC). Do not attempt to use it on any other
