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

operating a power tool. Do not use a power tool while tired or under the

inﬂuence of drugs, alcohol, or medication. A moment of inattention while

operating power tools may result in serious personal injury.

SKU 91511 PAGE 3

2. 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.

3. 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.

4. 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.

5. 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.

6. 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. 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.

1. Keep your work area clean and well lit. Cluttered benches and dark areas

invite accidents.

WORK AREA

2. 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.

3. 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. Store idle tools out of reach of children and other untrained persons. Tools

are dangerous in the hands of untrained users.

5. Maintain tools with care. Do not use a damaged tool. Tag damaged tools “Do

not use” until repaired.

SKU 91511 PAGE 4

6. 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. Tool service must be performed only by qualiﬁed repair personnel. Service

or maintenance performed by unqualiﬁed personnel could result in a risk of injury.

2. 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.

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.

ELECTRICAL SAFETY

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. 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.

4. 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.

5. 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 immediately.

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

SKU 91511 PAGE 5

resistance path to carry electricity away from the user, reducing the risk of electric

shock. (See Figure A.)

2. 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.)

3. 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. 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 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. 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.)

4. 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 PAGE 6

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. If you are using an extension cord outdoors, make sure it is marked with the

sufﬁx “W-A” (“W” in Canada) to indicate it is acceptable for outdoor use.

7. 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

electrician 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

replacement.

2. DANGER! Keep hands and ﬁngers away from cutting area and Saw

Blade. Use a appropriate push stick (not included) whenever possible.

3. 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 (sold separately) with 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. 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”.

6. 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. Make sure the Saw Blade remains wet at all times while cutting.

SKU 91511 PAGE 8

8. 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

component. Make sure to stand on a dry, insulated surface, such as a rubber

mat, while using this Wet Tile Saw.

10. Make sure to clean the water reservoir thoroughly after each use.

11. 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.

Rev 07j; 09e

13. Before using the Wet Tile Saw, make sure the Saw Blade is properly

mounted on the Saw Spindle. Make sure the Saw Blade is balanced, and is

not cracked or bent.

14. The Saw Blade will become hot while cutting. Allow the Saw Blade to

completely cool before touching.

15. 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. Do not force the workpiece into the Saw Blade when cutting. Apply

moderate pressure, allowing the Saw Blade to cut without being forced.

17. 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.

18. Never attempt to remove material stuck in the moving parts of the Wet Tile

Saw while it is plugged in and running.

19. 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. Industrial applications must follow OSHA requirements.

22. 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. 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.

24. 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.
