binding and excessive load on the
motor, leading to damage.

ELECTRICAL CONNECTION
WARNING! To reduce the risk of injury,
always use a Ground. Fault Circuit
Interrupter (GFCI) or a Portable Residual
Current Device (PRCD) device with
diamond coring equipment to reduce the
risk of shock hazards. Always position the
device GFCI as close as possible to the
power source.
The network voltage must conform to the
voltage indicated on the tool name plate.
Under no circumstances should the tool be
used when the power supply cable is
damaged. A damaged cable must be
replaced immediately by an authorized
Customer Service Center. Do not try to
repair the damaged cable yourself. The use
of damaged power cables can lead to an
electric shock.
GROUNDING
Tools marked “Grounding Required” 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”
