8. Do not abuse the Power Cord. Never use the Power Cord to carry the tool 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.
9. 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.
Personal Safety
10. 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.
11. 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.
12. Avoid accidental starting. Be sure the Power Switch is off before plugging in. Plugging in power
tools with the Power Switch on invites accidents.
13. 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.
14. 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.
15. Use safety equipment. Always wear eye protection and full face shield when using this saw.
Dust mask, nonskid safety shoes, hard hat, or hearing protection must be used for appropriate
conditions.
Tool Use and Care
16. Be sure the wet saw is used only on a stable platform.
17. 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.
18. 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.
19. 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.
20. Store idle tools out of reach of children and other untrained persons. Tools are dangerous in the
hands of untrained users.
21. Maintain tools with care, keeping them adjusted and clean. Properly maintained tools are less
likely to bind and are easier to control. Do not use a damaged tool. Tag damaged tools “Do not use”
until repaired.
22. Check for misalignment or binding of moving parts, breakage of parts, 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.
23. 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
24. Tool service must be performed only by qualified repair personnel. Service or maintenance
performed by unqualified personnel could result in a risk of injury.
25. When servicing a tool, use only identical replacement parts. Follow instructions in the “Inspec-
tion, 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.
Specific Safety Rules
1. Ensure that the directional arrow on the blade is mounted the same direction as the rotational
direction of the motor.
2. Always wear ANSI-approved safety impact eye goggles when using the tool. Using personal
safety devices reduce the risk for injury. Safety impact eye goggles and other safety equipment are
available from Harbor FreightTools.
3. Periodically check to be sure the Locking Arbor Nut (38) is tight, and the Blade is securely
fastened to the Arbor Shaft.
4.
Never try to cut freehand. Only cut tile that is securely held against the fence of the
SlidingTable or the Miter Gauge. Never try to cut pieces that are too small to be held
securely or that do not allow you to keep your hands safely away from the blade.
5. When starting this power tool, always ensure that it remains in place on a stable work platform.
6. Only use a GFCI-protected power source.
7. Never cut more than one tile at a time.
8. Allow the motor to come to full speed before cutting. If the blade vibrates or makes an unusual
sound, turn off the tool, unplug it, and investigate to find the source of the problem.
9. Let the blade come to a full stop before attempting to remove any jammed material.
10. Never walk away from the tool until the motor has come to a complete stop. The tool may create
unforeseen risk while the motor cycles down. Never leave the tool unattended when it is plugged
into an electrical outlet. Turn off the tool, and unplug it from its electrical outlet before leaving.
11. Never allow the blade to run dry. Cutting with a dry blade will cause excessive wear and
possible damage to the blade and motor.
12. WARNING! Some dust created by power sanding, sawing, grinding, drilling, and other construction
activities, contain chemicals known (to the State of California) to cause cancer, birth defects or other
reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline
silica from bricks and cement or other masonry products, arsenic and chromium from chemically
treated lumber. Your risk from these exposures varies, 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
approved safety equipment, such as those dust masks that are specially designed to filter out micro-
scopic particles. (California Health & Safety Code § 25249.5, et seq.)
13. WARNING! People with pacemakers should consult their physician(s) before using this product.
Electromagnetic fields in close proximity to a heart pacemaker could cause interference to or failure
of the pacemaker.
14. Use only 8” wet type blades specifically designed for tile cutting. Do not use any blade rated for
less than 4500 RPM.

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
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
DOUBLE INSULATED TOOLS: TOOLS WITH TWO PRONG PLUGS
4. Tools marked“Double Insulated”do not require grounding.
They have a special double insulation system which satis-
fies OSHA requirements and complies with the applicable
standards of Underwriters Laboratories, Inc., the Canadian
Standard Association, and the National Electrical Code.
(See Figure B.)
5. Double insulated tools may be used in either of the 120 volt
outlets shown in the following illustration. (See Figure B.)
Figure B
NOTE: The 93334 Wet Saw uses a grounded three-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 extension cords with inadequately sized wire causes a serious drop in voltage, resulting in loss
of power and possible tool damage. (See Figure C.)
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 C.)
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 C.)
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 C.)
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.

Operation
Preliminary Safety Check
Before starting the saw, with the power cord unplugged, and the Power Switch turned to the
Angle Guide
OFF (“O”) position, check to ensure:
a) The safety shield is in place and properly adjusted.
b) The cutting wheel can be revolved freely by hand.
c) The Sliding Table is in place.
d) The tub has enough water to keep the blade wet.
e) The Access Cover is in place.
Tool Rest (31)
f) The wet saw is positioned on a solid, level surface which is sturdy enough to safely support the
tool and your work materials.
Using the Sliding Table
Tool Rest Adjusters (34)
The SlidingTable is an advanced feature of
this product which aids in making safe and
accurate cuts.
1) Grasp the handle of the Support Bar (50) and pull
it straight out as far as needed to support the size
tile you plan to cut.
2) If necessary, remove the Support Rod (52) from its
storage location under the Access Cover (42), and
place it under the Support Bar (50).
3) Unlock the Sliding Table (1) by moving the Table
Locking Switch (54) to the “Unlock” position as
shown in the photo.
4) The Sliding Table may now be moved forward and
back along the top of the tool.
Basic Cutting Operation
1) Pull the Sliding Table (1) back far enough from the
Blade (37) to place the tile on the table.
2) After making sure that it is safe to turn the power
on, turn the Power Switch (14) to the ON position.
Allow the Blade to come up to full speed. Check
to be sure that the Blade is wet.
3) Using both hands, hold the tile securely against
the fence at the back edge of the Sliding Table.
WARNING: Do not allow your hands or fingers
to protrude over the notch at the back edge of
the SlidingTable. The Blade will enter this
space during the cutting operation.
4) Slowly push the Sliding Table and tile forward
into the Blade (37). Feed the workpiece smoothly
into the Cutting Blade (37). Do not apply heavy pressure or bump the workpiece against the Cutting
Blade. Try to allow the Cutting Blade to continue to turn at full speed as you work.

5) Be sure that the Blade remains wet during the cutting operation. If the Motor (22) slows down
appreciably, slow down your feed rate or pull the tile smoothly back from the Blade. If the Blade runs
dry, pull the tile smoothly back from the blade until the blade picks up water from the tank.
6) Do not use this saw over 30 minutes each hour, or longer than 20 minutes continuously. This will help
prevent overheating of the saw, and extend saw life.
7) When done cutting, move the Power Switch (6) to the OFF position. Allow the Cutting Blade to come
to a stop on its own. Do not manually stop the Cutting Blade by grabbing it or holding an object
against it. Stopping the Cutting Blade causes stress and possible damage to the gears and belts.
Using the Miter Gauge Attachment
Nuts (20)
The Miter Gauge Attachment can be used to easily cut several pieces of the same size or to
cut pieces at an angle.
1) Attach the accessory Miter Gauge to the Sliding
Table on the left side. Place it onto the fence at
the back edge of the table and secure it in place
using the screw knob.
2) To cut several pieces of the same size, loosen
the Miter Gauge and slide it along the fence until
it is at the desired distance from the slot in the
middle of the table. Tighten the Miter Gauge in
place. Position the tile against the fence and
against the miter gauge when cutting. Additional
tiles cut in the same way will have the same
dimension.
3) To cut pieces at an angle, adjust the Miter Gauge
so it is the desired distance from the slot at the
The Miter Gauge
middle of the tile. Loosen the knob at the top of
the miter gauge and move to the desired angle.
