WORK AREA
1.
2.
Keep your work area clean and well lit. Cluttered benches and dark areas
invite accidents.
Do not operate power tools in explosive atmospheres, such as in the
presence of flammable liquids, gases, or dust. Power tools create sparks
which may ignite flammables.
3.
Keep bystanders, children, and visitors away while operating a power tool.
Distractions can cause you to lose control. Protect others in the work area from
debris such as chips and sparks. Provide barriers or shields as needed.
PERSONAL SAFETY
1.
Stay alert. Watch what you are doing, and use common sense when oper-
ating a power tool. Do not use a power tool while tired or under the influ-
ence of drugs, alcohol, or medication. A moment of inattention while operat-
ing power tools may result in serious personal injury.
2.
3.
4.
5.
6.
Dress properly. Do not wear loose clothing or jewelry. Contain long hair.
Keep your hair, clothing, and gloves away from moving parts. Loose
clothes, jewelry, or long hair can be caught in moving parts.
Avoid accidental starting. Be sure the Power Switch is off before plugging
in. Carrying power tools with your finger on the Power Switch, or plugging in
power tools with the Power Switch on, invites accidents.
Remove adjusting keys or wrenches before turning the power tool on. A
wrench or a key that is left attached to a rotating part of the power tool may result
in personal injury.
Do not overreach. Keep proper footing and balance at all times. Proper
footing and balance enables better control of the power tool in unexpected
situations.
Use safety equipment. Always wear ANSI-approved safety goggles, a
dust mask or respirator, and hearing protection.
TOOL USE AND CARE
1.
Do not force the tool. Use the correct tool for your application. The correct
tool will do the job better and safer at the rate for which it is designed.

2.
3.
Do not use the power tool if the Power Switch does not turn it on or off.
Any tool that cannot be controlled with the Power Switch is dangerous and must
be replaced.
Disconnect the Power Cord Plug from the power source before making any
adjustments, changing accessories, or storing the tool. Such preventive
safety measures reduce the risk of starting the tool accidentally.
4.
5.
6.
Store idle tools out of reach of children and other untrained persons. Tools
are dangerous in the hands of untrained users.
Maintain tools with care. Do not use a damaged tool. Tag damaged tools “Do
not use” until repaired.
Check for misalignment or binding of moving parts, breakage of parts,
cracking or breakage of the Blade, and any other condition that may affect
the tool’s operation. If damaged, have the tool serviced before using. Many
accidents are caused by poorly maintained tools.
7.
Use only accessories that are recommended by the manufacturer for your
model. Accessories that may be suitable for one tool may become hazardous
when used on another tool.
SERVICE
1.
2.
Tool service must be performed only by qualified repair personnel. Service
or maintenance performed by unqualified personnel could result in a risk of injury.
When servicing a tool, use only identical replacement parts. Follow
instructions in the “Inspection, Maintenance, And Cleaning” section of this
manual. Use of unauthorized parts or failure to follow maintenance instructions
may create a risk of electric shock or injury.
ELECTRICAL SAFETY
1.
Grounded tools must be plugged into an outlet properly installed and
grounded in accordance with all codes and ordinances. Never remove the
grounding prong or modify the plug in any way. Do not use any adapter
plugs. Check with a qualified electrician if you are in doubt as to whether
the outlet is properly grounded. If the tools should electrically malfunction or
break down, grounding provides a low resistance path to carry electricity away
from the user.

2.
Double insulated tools are equipped with a polarized plug (one prong is
wider than the other). This plug will fit in a polarized outlet only one way. If
the plug does not fit fully in the outlet, reverse the plug. If it still does not
fit, contact a qualified electrician to install a polarized outlet. Do not
change the plug in any way. Double insulation
eliminates the need for the
three wire grounded power cord and grounded power supply system.
3.
4.
5.
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.
Do not expose power tools to external rain or wet conditions. Water
entering unprotected parts of this power tool will increase the risk of
electric shock.
Do not abuse the Power Cord. Never use the Power Cord to carry the tools
or pull the Plug from an outlet. Keep the Power Cord away from heat, oil,
sharp edges, or moving parts. Replace damaged Power Cords immedi-
ately. Damaged Power Cords increase the risk of electric shock.
6.
When operating a power tool outside, use an outdoor extension cord
marked “W-A” or “W”. These extension cords are rated for outdoor use, and
reduce the risk of electric shock.
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 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 fit the outlet, have a proper
outlet installed by a qualified electrician.
GROUNDED TOOLS:TOOLS WITH THREE PRONG PLUGS
1.
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 elec-
tric shock. (See Figure A.)
2.
3.
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. (See Figure A.)
Your tool must be plugged into an appropriate outlet, properly installed and
grounded in accordance with all codes and ordinances. The plug and outlet
should look like those in the following illustration. (See Figure A.)
FIGURE A
EXTENSION CORDS
1.
2.
Grounded tools require a three wire extension cord. Double Insulated 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 in loss of power and possible tool damage.
(See Figure B, next page.)
3.
4.
The smaller the gauge number of the wire, the greater the capacity of the cord.
For example, a 14 gauge cord can carry a higher current than a 16 gauge cord.
(See Figure B.)
When using more than one extension cord to make up the total length, make
sure each cord contains at least the minimum wire size required. (See Figure B.)
SKU 91511

5.
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 Figure B.)
6.
7.
If you are using an extension cord outdoors, make sure it is marked with the suf-
fix “W-A” (“W” in Canada) to indicate it is acceptable for outdoor use.
Make sure your extension cord is properly wired and in good electrical condition.
Always replace a damaged extension cord or have it repaired by a qualified elec-
trician before using it.
8.
Protect your extension cords from sharp objects, excessive heat, and damp or
wet areas.

SPECIFIC SAFETY RULES
1.
Maintain labels and nameplates on the Wet Tile Saw. These carry important
information. If unreadable or missing, contact Harbor Freight Tools for a replace-
ment.
2.
3.
DANGER! Keep hands and fingers away from cutting area and Saw
Blade. Use a appropriate push stick (not included) whenever possible.
Check Blade Guard for proper upward/downward movement before each
use. Do not operate the Wet Tile Saw if the Blade Guard does not move
freely. Never clamp or tie the Blade Guard into the upward position. If the
Wet Tile Saw is accidentally dropped, the Blade Guard may be bent. Raise the
Blade Guard and make sure it moves freely and does not touch the Saw Blade or
any other part of the Saw, in all angles and depths of cut.
4.
Always use Diamond Blades with a 7” diameter, 5/8” round arbor hole, and
rated at a minimum 3,600 RPM. Blades that do not match the mounting
hardware of the Wet Tile Saw or that are rated at less than the required minimum
RPM will run eccentrically causing loss of control or may fly off the Saw.
5.
6.
Use the Wet Tile Saw only for cutting ceramic tile, quarry tile, marble, terra
cotta, and slate with a maximum thickness of 1-1/4”.
Do not use the Wet Tile Saw for cutting metals, or for cutting curves. This
may cause the Saw Blade to break, and reduce its service life.
7.
8.
Make sure the Saw Blade remains wet at all times while cutting.
Always keep the water level at the recommended level (1-1/2” deep). Do not
overfill or allow the Wet Tile Saw to run dry.
9.
Avoid splashing water on the Motor, Power Switch, or any electrical compo-
nent. Make sure to stand on a dry, insulated surface, such as a rubber mat,
while using this Wet Tile Saw.
10.
11.
Make sure to clean the water reservoir thoroughly after each use.
Never use damaged or incorrect Saw Blade washers or nuts. The Saw
Blade’s washers and nut were specially designed for your Saw, for optimum
performance and safety of operation.
12.
To avoid accidental injury, always wear heavy duty work gloves and long
sleeved work shirt when changing a Saw Blade.

mounted on the Saw Spindle. Make sure the Saw Blade is balanced, and is
not cracked or bent.
14.
15.
The Saw Blade will become hot while cutting. Allow the Saw Blade to
completely cool before touching.
Allow the Saw Blade to spin up to full speed before feeding a workpiece
into it. When turning off the Saw, allow the Saw Blade to spin down and stop on
its own. Do not press against the Saw Blade to stop it.
16.
17.
18.
19.
Do not force the workpiece into the Saw Blade when cutting. Apply moder-
ate pressure, allowing the Saw Blade to cut without being forced.
Turn off the Wet Tile Saw and allow the Saw Blade to stop on its own if the
Saw Blade is to be backed out of an uncompleted cut.
Never attempt to remove material stuck in the moving parts of the Wet Tile
Saw while it is plugged in and running.
When cutting a large workpiece, make sure its entire length is properly
supported. If necessary, use a roller stand (not included) with larger
workpieces.
20.
Never stand on the Wet Tile Saw. Serious injury could result if the Wet Tile
Saw is tipped or if the rotating Saw Blade is accidently contacted.
21.
22.
Industrial applications must follow OSHA requirements.
For your safety: In extreme working conditions, sensors in the Wet Tile Saw
will automatically switch off the Motor to prevent overheating. In this event, turn
the Power Switch to its “OFF” position. Wait five minutes or until the Motor has
cooled. Depress the Circuit Breaker. Then, turn the Power Switch to its “ON”
position to resume cutting.
23.
24.
Always turn off the Wet Tile Saw and unplug the Power Cord from its
electrical outlet before changing accessories or performing any inspection,
maintenance, or cleaning procedures.
Use the right tool or attachment for the job. Do not attempt to force a
small tool or attachment to do the work of a larger industrial tool or attachment.
There are certain applications for which this product was designed. It will do the
job better and more safely at the rate for which it was intended. Do not modify
