GROUNDING
-
WARNING:
Improperly connecting the grounding wire can result in the risk
of electric shock. Check with a qualified electrician if you are in doubt as to
whether the outlet is properly grounded. Do not modify the plug provided with
the tool. Never remove the grounding prong from the plug. Do not use the tool
if the cord or plug is damaged. If damaged, have it repaired by a DIAMOND
service facility before use. If the plug will not fit the outlet, have a proper outlet
installed by a qualified electrician.
Grounded Tools (Single Insulated Tool):
-
Tools with Three Prong Plugs Tools have a three wire cord and three prong
grounding plug. The plug must be connected to a properly grounded outlet. If the
tool should electrically malfunction or break down, grounding provides a low
resistance path to carry electricity away from the user, reducing the risk of electric
shock. The grounding prong in the plug is connected through the green wire inside
the cord to the grounding system in the tool. The green wire in the cord must be the
only wire connected to the tool’s grounding system and must never be attached to an
electrically “live” terminal. Your tool must be plugged into an appropriate outlet,
properly installed and grounded in accordance with all codes and ordinances.
Double Insulated Tools:
-
Tools with Two Plugs. Tool marked “Double Insulated” do not require grounding.
They have a special double insulation system.
EXTENSION CORDS
-
Grounded tools require a three wire extension cord. Double insulation tools can use
either a two or three wire extension cord. As the distance from the supply outlet
increases, you must use a heavier gauge extension cord. Using extension cords with
inadequately sized wire causes a serious drop in voltage, resulting loss of power and
possible tool damage. Refer to the table shown to determine the required minimum
wire size.
