Never remove the grounding prong or modify the plug in any way. Do not use any adapter plugs. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. If the tools should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user. 5. Double insu

EXTENSION CORDS 1. Grounded tools require a three wire extension cord. Double Insulated tools can use either a two or three wire extension cord. 2.

Using extension cords with inadequately sized wire causes a serious drop in voltage, resulting in loss of power and possible tool damage. (See Figures C.) 3. The smaller the gauge number of the wire, the greater the capacity of the cord. For example, a 14
