General Power Tool Safety
Warnings
WARNING Read all safety
warnings and instructions.
Failure to follow the warnings and
instructions may result in electric
shock, re and/or serious injury.
Save all warnings and
instructions for future reference.
The term ″power tool″ in the
warnings refers to your mains-
operated (corded) power tool or
battery-operated (cordless) power
tool.
1. Work area safety
a.Keep work area clean and well lit.
Cluttered or dark areas invite acci-
dents.
b.Do not operate power tools in
explosive atmospheres, such as in
the presence of ammable liquids,
gases or dust. Power tools create
sparks which may ignite the dust or
fumes.
c. Keep children and bystanders
away while operating a power tool.
Distractions can cause you to lose
control.
2. Electrical safety
a.Power tool plugs must match the
outlet. Never modify the plug in
any way. Do not use any adapter

Page 3SKU 40315 For technical questions, please call 1-800-444-3353.
plugs with grounded power tools.
Unmodied plugs and matching out-
lets will reduce risk of electric shock.
b.Avoid body contact with grounded
surfaces such as pipes, radiators,
ranges and refrigerators. There is
an increased risk of electric shock if
your body is grounded.
c. Do not expose power tools to rain
or wet conditions. Water entering
a power tool will increase the risk of
electric shock.
d.Do not abuse the cord. Never use
the cord for carrying, pulling or
unplugging the power tool. Keep
cord away from heat, oil, sharp
edges or moving parts. Damaged
or entangled cords increase the risk
of electric shock.
e.When operating a power tool out-
doors, use an extension cord suit-
able for outdoor use. Use of a cord
suitable for outdoor use reduces the
risk of electric shock.
f. If operating a power tool in a damp
location is unavoidable, use a
Ground Fault Circuit Interrupter
(GFCI) protected supply. Use of
a GFCI reduces the risk of electric
shock.
3. Personal safety
a.Stay alert, watch what you are do-
ing and use common sense when
operating a power tool. Do not use
a power tool while you are tired
or under the inuence of drugs,
alcohol or medication. A moment
of inattention while operating power
tools may result in serious personal
injury.
b.Use safety equipment. Always
wear ANSI-approved eye protec-
tion. Safety equipment such as dust
mask, non-skid safety shoes, hard
hat, or hearing protection used for
appropriate conditions will reduce
personal injuries.
c. Keep guards in place and in good
working order.
d.Prevent unintentional starting.
Ensure the switch is in the off-po-
sition before connecting to power
source and/or battery pack, pick-
ing up or carrying the tool. Carry-
ing power tools with your nger on
the switch or energizing power tools
that have the switch on invites acci-
dents.
e.Remove any adjusting key or
wrench before turning the power
tool on. A wrench or a key left at-
tached to a rotating part of the power
tool may result in personal injury.
f. Do not overreach. Keep proper
footing and balance at all times.
This enables better control of the
power tool in unexpected situations.
g.Dress properly. Do not wear loose
clothing or jewelry. Keep your
hair, clothing and gloves away
from moving parts. Loose clothes,
jewelry or long hair can be caught in
moving parts.
h.If devices are provided for the con-
nection of dust extraction and col-
lection facilities, ensure these are
connected and properly used. Use
of these devices can reduce dust-
related hazards.
4. Power tool use and care
a.Do not force the power tool. Use
the correct power tool for your ap-
plication. The correct power tool will

Page 4SKU 40315 For technical questions, please call 1-800-444-3353.
do the job better and safer at the rate
for which it was designed.
b.Do not use the power tool if the
switch does not turn it on and off.
Any power tool that cannot be con-
trolled with the switch is dangerous
and must be repaired.
c. Disconnect the plug from the
power source and/or the battery
pack from the power tool before
making any adjustments, chang-
ing accessories, or storing power
tools. Such preventive safety mea-
sures reduce the risk of starting the
power tool accidentally.
d.Store idle power tools out of the
reach of children and do not allow
persons unfamiliar with the power
tool or these instructions to oper-
ate the power tool. Power tools are
dangerous in the hands of untrained
users.
e.Maintain power tools. Check for
misalignment or binding of moving
parts, breakage of parts and any
other condition that may affect the
power tool’s operation. If dam-
aged, have the power tool repaired
before use. Many accidents are
caused by poorly maintained power
tools.
f. Keep cutting tools sharp and
clean. Properly maintained cutting
tools with sharp cutting edges are
less likely to bind and are easier to
control.
g.Use the power tool, accessories
and tool bits etc. in accordance
with these instructions, taking into
account the working conditions
and the work to be performed. Use
of the power tool for operations differ-
ent from those intended could result
in a hazardous situation.
5. Service
a.Have your power tool serviced by
a qualied repair person using
only identical replacement parts.
This will ensure that the safety of the
power tool is maintained.
Vibration Safety
This tool vibrates during use. Re-
peated or long-term exposure to
vibration may cause temporary or
permanent physical injury, particularly
to the hands, arms and shoulders. To
reduce the risk of vibration-related
injury:
1. Anyone using vibrating tools regu-
larly or for an extended period should
rst be examined by a doctor and
then have regular medical check-
ups to ensure medical problems are
not being caused or worsened from
use. Pregnant women or people
who have impaired blood circulation
to the hand, past hand injuries, ner-
vous system disorders, diabetes, or
Raynaud’s Disease should not use
this tool. If you feel any medical or
physical symptoms related to vibra-
tion (such as tingling, numbness, and
white or blue ngers), seek medical
advice as soon as possible.
2. Do not smoke during use. Nico-
tine reduces the blood supply to the
hands and ngers, increasing the risk
of vibration-related injury.
3. Wear suitable gloves to reduce the
vibration effects on the user.

Page 5SKU 40315 For technical questions, please call 1-800-444-3353.
4. Use tools with the lowest vibration
when there is a choice between dif-
ferent processes.
5. Include vibration-free periods each
day of work.
6. Grip tool as lightly as possible (while
still keeping safe control of it). Let
the tool do the work.
7. To reduce vibration, maintain the tool
as explained in this manual. If any
abnormal vibration occurs, stop use
immediately.

ELECTRICAL
OUTLET
TILE SAW
DRIP LOOP
Figure 1
Always arrange a “drip loop” in the
Power Cord/Plug (34) connecting
the Tile Saw to a 120 volt, ground-
ed, electrical outlet. A drip loop is
that part of the Power Cord below the
level of the outlet, or the connector
if an extension cord is used, to pre-
vent water traveling along the Power
Cord and coming in contact with the
outlet. If the Power Plug or electrical
outlet does get wet, do not unplug the
Power Cord. Disconnect the fuse or
circuit breaker that supplies power to
the tool. Then, unplug and examine
for presence of water in the outlet.
See Figure 1, above.
15. Use cold water only. Never use
hot water.
16. Never run the Tile Saw without a
water supply. Running the unit with-
out a water supply will cause irrepa-
rable damage.
17. Make sure the water supply used
for the Tile Saw is not dirty, sandy,
and does not contain any corro-
sive chemicals.
18. Make sure to change the water
when necessary while in use and
clean and rinse out the Tub after
every use.
19. Never leave the Tile Saw unattend-
ed when it is plugged into an elec-
trical outlet. Turn off the Tile Saw,
and unplug it from its electrical outlet.
20. Always keep the water level at the
recommended level. Fill the Tray
(17) until it is about 3/4 completely
submerged, but do not overll.
21. Avoid splashing water on the
Motor (42), Power Switch, Power
Cord/Plug, or any other electrical
component. Make sure to stand on
a dry, insulated surface such as a
rubber mat while using the Tile Saw.
22. To avoid accidental injury, always
wear heavy duty work gloves when
changing the Saw Blade. Before
using the Tile Saw, make sure the
Saw Blade is properly and securely
mounted on the Saw Spindle. Make

to its “OFF” position. Wait ve min-
utes or until the Motor has cooled.
Making sure your hands are dry, de-
press the Circuit Breaker. Then, turn
the Power Switch to its “ON” position
to resume cutting.
32. Never attempt to cut more than
one tile at a time.
33. Never attempt to cut freehand.
Make sure the tile to be cut is
pressed rmly against the Cutting
Guide (57).
34. Never cut pieces too small to be
held securely against the Cutting
Guide without leaving enough
space for the hand to be a safe
distance from the Saw Blade.
35. Make sure the tile to be cut off has
sufcient room to move sideways.
Failure to do so may result in the tile
binding against the Saw Blade.
36. Make sure the surrounding area of
the Table is clear with the excep-
tion of the tile to be cut.
37. Always turn off the Tile Saw and
unplug it from its electrical outlet
before changing accessories or
performing any inspection, mainte-
nance, or cleaning procedures.
38. WARNING! Some dust created
by power sanding, sawing, grind-
ing, drilling, and other construction
activities, contain chemicals known
(to the State of California) to cause
cancer, birth defects or other repro-
ductive harm. Some examples of
these chemicals are: lead from lead-
based paints, crystalline silica from
bricks and cement and other masonry
products, arsenic and chromium from
chemically treated lumber. Your risk
from these exposures varies, depend-
ing on how often you do this type of
work. To reduce your exposure to
these chemicals: work in well venti-
lated areas, and work with approved

avoid electrical shock.
• Any power cord must be properly
grounded. Ground Fault Circuit Inter-
rupter (GFCI) should also be imple-
mented – it prevents sustained elec-
trical shock.
15. Some dust created by power sand-
ing, sawing, grinding, drilling,
and other construction activities,
contains chemicals known [to the
State of California] to cause can-
cer, birth defects or other repro-
ductive harm. Some examples of
these chemicals are:
• Lead from lead-based paints
• Crystalline silica from bricks and ce-
ment or other masonry products
• Arsenic and chromium from chemi-
cally treated lumber
Your risk from these exposures var-
ies, depending on how often you do
this type of work. To reduce your
exposure to these chemicals: work in
a well ventilated area, and work with

GROUNDING
TO PREVENT
ELECTRIC SHOCK
AND DEATH FROM
INCORRECT GROUNDING
WIRE CONNECTION:
Check with a qualied
electrician if you are in doubt
as to whether the outlet is
properly grounded. Do not
modify the power cord plug
provided with the tool. Never
remove the grounding prong
from the plug. Do not use the
tool if the power cord or plug
is damaged. If damaged, have
it repaired by a service facility
before use. If the plug will not
t the outlet, have a proper
outlet installed by a qualied
electrician.
Grounded Tools: Tools with Three
Prong Plugs
1. This Tile Saw comes with a
3-prong power cord.
2. Tools marked with “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. (See 3-Prong Plug
and Outlet.)
3. The grounding prong in the plug
is connected through the green
wire inside the cord to the ground-
ing 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. (See
3-Prong Plug and Outlet.)
4. The tool must be plugged into
an appropriate outlet, properly
installed and grounded in accor-
dance with all codes and ordinanc-
es. The plug and outlet should look
like those in the preceding illustration.
(See 3-Prong Plug and Outlet.)
Double Insulated Tools: Tools
with Two Prong Plugs
1. Tools marked “Double Insulated”
do not require grounding. They
have a special double insulation
system which satises OSHA require-
ments and complies with the applica-
ble standards of Underwriters Labo-
ratories, Inc., the Canadian Standard
Association, and the National Electri-
cal Code. (See Outlets for 2-Prong
Plug.)

Page 11SKU 40315 For technical questions, please call 1-800-444-3353.
2. Double insulated tools may be used
in either of the 120 volt outlets shown
in the preceding illustration. (See
Outlets for 2-Prong Plug.)
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. As the distance from the supply outlet
increases, you must use a heavier
gauge extension cord. Using exten-
sion cords with inadequately sized
wire causes a serious drop in voltage,
resulting in loss of power and pos-
sible tool damage.
(See Table A.) The smaller the
gauge number of the wire, the greater
the capacity of the cord. For ex-
ample, a 14 gauge cord can carry a
higher current than a 16 gauge cord.
(See Table A.)
3. When using more than one exten-
sion cord to make up the total length,
make sure each cord contains at
least the minimum wire size required.
(See Table A.)
4. If you are using one extension cord
for more than one tool, add the
nameplate amperes and use the sum
to determine the required minimum
cord size. (See Table A.)
5. If you are using an extension cord
outdoors, make sure it is marked with
the sufx “W-A” (“W” in Canada) to
indicate it is acceptable for outdoor
use.
6. Make sure the extension cord is prop-
erly wired and in good electrical con-
dition. Always replace a damaged
extension cord or have it repaired by
a qualied electrician before using it.
7. Protect the extension cords from
sharp objects, excessive heat, and
damp or wet areas.

OPERATING INSTRUCTIONS
Read the ENTIRE IMPORTANT
SAFETY INFORMATION section
at the beginning of this manual
including all text under
subheadings therein before set
up or use of this product.
Tool Set Up
TO PREVENT
SERIOUS INJURY
FROM ACCIDENTAL
OPERATION: Turn the Power
Switch of the tool to its “OFF”
position and unplug the tool
from its electrical outlet
before performing any
inspection, maintenance, or
cleaning procedures.
1. Use Clamping Plate (56) to secure
and support smaller work pieces to
the built-in fence. Holding work by
hand or against your body is unstable
and may lead to loss of control.
2. Do not force tool. Use the cor-
rect tool for your application. The
correct tool will do the job better and
safer at rate for which it is designed.
3. Do not use the power tool if the
Power Switch does not turn it on
or off. Any tool that cannot be con-
trolled with its Power Switch is dan-
gerous and must be replaced.
4. Disconnect Power Cord Plug from
the power source before making
any adjustments, changing acces-
sories, or storing the tool. Such
preventive safety measures reduce
risk of starting the tool accidentally.
5. Store idle tools out of reach of chil-
dren and other untrained persons.
Tools are dangerous in the hands of
untrained users.
6. Maintain tools with care. Keep
tools clean. Properly maintained
tools are easier to control. Do not
use a damaged tool. Tag damaged
tools “Do not use” until repaired.
7. Check for misalignment or binding
of moving parts, breakage of parts,
and any other condition that may
affect the tool’s operation. If dam-
aged, have the tool serviced before
using. Many accidents are caused
by poorly maintained tools.
8. Use only accessories that are
recommended by the manufacturer
for your tool. Accessories suitable
for one tool may become hazardous
when used on another tool.
Work Piece and Work Area Set Up
1. Designate a work area that is clean
and well lit. The work area must not
allow access by children or pets to
prevent injury and distraction.
2. Route the power cord along a safe
route to reach the work area with-
out creating a tripping hazard or
exposing the power cord to pos-
sible damage. The power cord must
reach the work area with enough
extra length to allow free movement
while working.
3. Secure loose work pieces using
clamps (not included) to prevent
movement while working.

General Operating Instructions
1. Fill Tray (17) with water and carefully
slide Tray under Blade. Make sure
water level is deep enough to cover
lower edge of Cutting Wheel Blade,
but not so deep as to spill over edge
of Tray. (See Figure 3, below.)
2. Loosen Star Knob (20) and adjust the
Cutting Guide (57) to set desired cut-
ting width. Retighten the Star Knob.
3. If necessary, loosen second Star
Knob (53) and tilt Table (51) to adjust
angle of cut. Retighten Star Knob.
4. Connect Power Cord/Plug (34) of Tile
Saw to the nearest 120 volt, ground-
ed, electrical outlet.
5. Put on ANSI-approved safety
glasses under ANSI-approved
safety impact full face shield.
6. Fill water in Tray (17) to proper level.
Turn Power Switch (21) to its “ON”
position, and allow Blade to spin up
to full speed.

off Tile Saw. Unplug machine, and
rell Tray to appropriate level. Re-
start Tile Saw.
8. Place workpiece you are cutting
rmly against Cutting Guide (57) and
slowly feed workpiece into Blade.
9. CAUTION! Keep hands and ngers
away from Blade. Also hold the work-
piece you are cutting rmly against
Cutting Guide (57) throughout cutting
process. Failure to do so may cause
