follow all instructions listed below, may result in
electric shock, fire and/or serious personal injury.
READ ALL INSTRUCTIONS
KNOW YOUR POWER TOOL. Read the operator’s
manual carefully. Learn the saw’s applications and
limitations as well as the specific potential hazards related
to this tool.
GUARD AGAINST ELECTRICAL SHOCK BY PREVENT-
ING BODY CONTACT WITH GROUNDED SURFACES.
For example, pipes, radiators, ranges, refrigerator enclosures.
KEEP GUARDS IN PLACE and in good working order.
REMOVE ADJUSTING KEYS AND WRENCHES. Form
habit of checking to see that keys and adjusting wrenches
are removed from tool before turning it on.
KEEP WORK AREA CLEAN. Cluttered areas and benches
invite accidents. DO NOT leave tools or pieces of tile on
the saw while it is in operation.
DO NOT USE IN DANGEROUS ENVIRONMENTS. Do
not use power tools in damp or wet locations or expose
to rain. Keep the work area well lit.
KEEP CHILDREN AND VISITORS AWAY. All visi-
tors should wear safety glasses and be kept a safe
distance from work area. Do not let visitors contact
tool or extension cord while operating.
MAKE WORKSHOP CHILDPROOF with padlocks and
master switches, or by removing starter keys.
DON’T FORCE TOOL. It will do the job better and safer
at the feed rate for which it was designed.
USE RIGHT TOOL. Don’t force the tool or attachment to
do a job it was not designed for. Don’t use it for a purpose
not intended.
USE THE PROPER EXTENSION CORD. Make sure your
extension cord is in good condition. Use only a cord heavy
enough to carry the current your product will draw. An
undersized cord will cause a drop in line voltage resulting in loss of power and overheating. A wire gauge size
(A.W.G.) of at least 14 is recommended for an extension
cord 25 feet or less in length. If in doubt, use the next
heavier gauge. The smaller the gauge number, the heavier
the cord.
DRESS PROPERLY. Do not wear loose clothing, gloves,
neckties, or jewelry. They can get caught and draw you
into moving parts. Rubber gloves and nonskid footwear
(rubber soled boots) are recommended when working
outdoors. Also wear protective hair covering to contain
long hair.
ALWAYS WEAR SAFETY GLASSES WITH SIDE
SHIELDS. Everyday eyeglasses have only impact-
resistant lenses, they are NOT safety glasses.
SECURE WORK. Use clamps or a vise to hold work
when practical, it is safer than using your hand and frees
both hands to operate the tool.
DON’T OVERREACH. Keep proper footing and
balance at all times.
MAINTAIN TOOLS WITH CARE. Keep tools sharp
and clean for better and safer performance. Follow instructions for lubricating and changing accessories.
DISCONNECT TOOLS. When not in use, before
servicing, or when changing attachments, wheels, bits,
cutters, etc., all tools should be disconnected.
AVOID ACCIDENTAL STARTING. Be sure switch is off
when plugging in any tool.
USE RECOMMENDED ACCESSORIES. Consult the
operator’s manual for recommended accessories. The
use of improper accessories may risk injury.
NEVER STAND ON TOOL. Serious injury could occur if
the tool is tipped or if the cutting tool is unintentionally
contacted.
CHECK DAMAGED PARTS. Before further use of the
tool, a guard or other part that is damaged should be
carefully checked to determine that it will operate properly
and perform its intended function. Check for alignment
of moving parts, binding of moving parts, breakage of
parts, mounting and any other conditions that may affect
its operation. A guard or other part that is damaged must
be properly repaired or replaced by an authorized service
center to avoid risk of personal injury.
USE THE RIGHT DIRECTION OF FEED. Feed work into
a wheel or cutter against the direction of rotation of wheel
or cutter only.
NEVER LEAVE TOOL RUNNING UNATTENDED. TURN
THE POWER OFF. Don’t leave tool until it comes to a
complete stop.
PROTECT YOUR LUNGS. Wear a face or dust mask if
the cutting operation is dusty.
PROTECT YOUR HEARING. Wear hearing protection
during extended periods of operation.
DO NOT ABUSE CORD. Never yank cord to disconnect
from receptacle. Keep cord away from heat, oil, and sharp
edges.
ALWAYS USE AN OUTDOOR EXTENSION CORD
MARKED “W-A” OR “W”. These cords are rated for
outdoor use and reduce the risk of electric shock.
ALWAYS KEEP THE WHEEL GUARD IN PLACE and in
working order.

EXTENSION CORDS
Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the tool’s plug.
When using a power tool at a considerable distance from the
power source, use an extension cord heavy enough to carry
the current that the tool will draw. An undersized extension
cord will cause a drop in line voltage, resulting in a loss of
power and causing the motor to overheat. Use the chart
provided below to determine the minimum wire size required
in an extension cord. Only round jacketed cords listed by
Underwriter’s Laboratories (UL) should be used.

**Used on 12 gauge - 20 amp circuit.
NOTE: AWG = American Wire Gauge
Always use an extension cord that is designed for outside
use. This is indicated by the letters “W-A” or “W” on the
cord’s jacket.
Before using an extension cord, inspect it for loose or
exposed wires and cut or worn insulation.
Use only extension cords that are intended for outdoor use.
These extension cords are identified by a marking “Acceptable for use with outdoor appliances; store indoors while not
in use”. Use only extension cords having an electrical rating
not less than the rating of the product. Do not use damaged
extension cords. Examine extension cord before using and
replace if damaged. Do not abuse extension cords and do
not yank on any cord to disconnect. Keep cord away from
heat and sharp edges. Always disconnect the extension
cord from the receptacle before disconnecting the product
from the extension cord.
WARNING:
Keep the extension cord clear of the working area.
Position the cord so that it will not get caught on
lumber, tools or other obstructions while you are
working with a power tool. Failure to do so can
result in serious personal injury.
ELECTRICAL CONNECTION
This tool is powered by a precision built electric motor. It
should be connected to a power supply that is 120 V, AC
only (normal household current), 60 Hz. Do not operate
this tool on direct current (DC). A substantial voltage drop
will cause a loss of power and the motor will overheat. If the
saw does not operate when plugged into an outlet, double
check the power supply.
SPEED AND WIRING
The no-load speed of this tool is approximately 4,000 rpm.
This speed is not constant and decreases under a load or
with lower voltage. For voltage, the wiring in a shop is as
important as the motor’s horsepower rating. A line intended
only for lights cannot properly carry a power tool motor. Wire
that is heavy enough for a short distance will be too light for
a greater distance. A line that can support one power tool
may not be able to support two or three tools.
GROUNDING INSTRUCTIONS
See Figure 1.
This tool must be grounded. In the event of a malfunction or
breakdown, grounding provides a path of least resistance
for electric current to reduce the risk of electric shock. This
tool is equipped with an electric cord having an equipmentgrounding 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.
Do not modify the plug provided. If it will not fit the outlet,
have the proper outlet installed by a qualified electrician.
WARNING:
Improper installation of the grounding plug can
result in a risk of electric shock. When repair or
replacement of the cord is required, do not connect the grounding wire to either flat blade terminal.
The wire with insulation having an outer surface
that is green with or without yellow stripes is the
grounding wire.
Check with a qualified electrician or service personnel if the
grounding instructions are not completely understood, or if
in doubt as to whether the tool is properly grounded.
Repair or replace a damaged or worn cord immediately.
WARNING:
Check extension cords before each use. If damaged
replace immediately. Never use tool with a damaged cord since touching the damaged area could
cause electrical shock resulting in serious injury.
This product is for use on a nominal 120 volt circuit and
has a grounding plug similar to the plug illustrated in
figure 1. Only connect the product to an outlet having the
same configuration as the plug. Do not use an adapter with
this product.

ELECTRICAL
Ground Fault Circuit Interrupter (GFCI) protection should be
provided on the circuit(s) or outlet(s) to be used for the tile
saw. Outlets are available having built-in GFCI protection
and may be used for this measure of safety.
If the saw is used with an extension cord, ensure the connection of the tool’s power cord and the extension cord are
not on the ground.
If a protected outlet is not available, do not use the saw
until an outlet can be changed or auxiliary protection can
be obtained. These auxiliary protection devices are available
at your local retailer.
POSITION OF THE TILE SAW
See Figure 2.
To avoid the possibility of the tool plug or outlet getting
wet, position tile saw to one side of a wall-mounted outlet
to prevent water from dripping onto the outlet or plug. The
operator should arrange a “drip loop” in the cord connecting
the saw to the outlet. The “drip loop” is that part of the cord
below the level of the outlet, or the connector if an extension
cord is used, to prevent water traveling along the cord and
coming in contact with the outlet.
If the plug or outlet does get wet, DO NOT unplug the cord.
Disconnect the fuse or circuit breaker that supplies power
to the tool then unplug and examine for the presence of
water in the outlet.
