SAFETY INSTRUCTIONS
Page 6
WARNING: In case of a malfunction or breakdown,
grounding provides a path of least resistance for electric
current to reduce the risk of electric shock. This tile saw
is equipped with an electric cord having an equipment-
grounding conductor and a grounding plug. The plug must
be plugged into a matching outlet that is properly installed
and grounded in accordance with all local codes and
ordinances.
WARNING: Use of a temporary adapter is not
permitted in Canada.
FIG. 2
GROUND INSTRUCTION
In order to prevent potential electrical shock and injury, the
following electrical safety precautions and symbols should
be followed at all times!
PERMANENTLY CONNECTED TOOLS
This tile saw can be permanently connected to a grounded,
metal, wiring system or to a system that has an equipment-
grounding conductor.
Ground-fault circuit interrupter (GFCI) protection should be
provided on the circuit or outlet to be used for the tile saw.
Receptacles are available having built-in GFCI protection
and may be used for this measure of safety.
GUIDELINES FOR EXTENSION CORDS
Use a proper extension cord. Make sure extension cords
are in good condition. When using an extension cord, be
sure to use a cord that is heavy enough to carry the drawn
current needed by the saw. An undersized cord will cause
a drop in line voltage, resulting in loss of power and
overheating.
Do not modify the plug provided – if it will not t the outlet;
have the proper outlet installed by a qualied electrician.
Improper connections of the equipment-grounding
conductor can result in a risk of electric shock. The
equipment-grounding conductor is the insulated conductor
that has an outer surface that is green, with or without
yellow stripes. If repair or replacement of the electric cord
or plug is necessary, do not connect the equipment-
grounding conductor to a live terminal
Check with a qualied electrician or service personnel if
the grounding instructions are not completely understood,
or if in doubt as to whether the tile saw is properly grounded.
Use only 3-wire extension cords that have 3-prong
grounding plugs and 3-pole receptacles that accept the
tile saw’s plug.
• Repair or replace a damaged or worn cord immediately.
Grounded, cord-connected tools intended for use on a
supply circuit having a nominal rating less than 150 Volts:
This tile saw is intended for use on a circuit that has an
outlet that looks like the one shown in Sketch A of Figure 2.
The tile saw has a grounding plug that looks like the plug
illustrated in Sketch A of Figure 2.
A temporary adapter, which looks like the adapter
illustrated in sketches B and C, may be used to connect
this plug to a 2-pole receptacle as shown in Sketch B, if
a properly grounded outlet is not available. The temporary
adapter should be used only until a properly grounded
outlet can be installed by a qualied electrician. The
greencolored rigid ear, lug, and the like, extending from
the adapter, must be connected to a permanent ground
such as a properly grounded outlet box.
The table below shows the correct size to use, depending
on the cord length and nameplate amperage rating. If
in doubt, use the next heavier gauge. The smaller the gauge
number, the heavier the cord.
Be sure extension cords are properly wired and in good
condition. Always replace a damaged extension cord
or have it repaired by a qualied technician before using it.
Protect extension cords from sharp objects, excessive heat,
and damp or wet areas.
