6. Use the right tool for the job. Do not attempt to force a small tool or attachment  
to do the work of a larger industrial tool. There are certain applications for  
which this tool was designed. Do not modify this tool and do not use this tool  
for a purpose for which it was not intended.  
7. Dress properly. Do not wear loose clothing or jewelry as they can be caught  
in moving parts. Protective, electrically nonconductive clothes and nonskid  
footwear are recommended when working. Wear restrictive hair covering to  
contain long hair.  
8. Use eye and ear protection. Always wear ANSI approved impact safety  
goggles.  
9. Do not overreach. Keep proper footing and balance at all times. Do not reach  
over or across running machines.  
10. Maintain tools with care. Keep tools sharp and clean for better and safer  
performance. Follow instructions for lubricating and changing accessories.  
Inspect tool cords periodically and, if damaged, have them repaired by an  
authorized technician. The handles must be kept clean, dry, and free from oil  
and grease at all times.  
11. Disconnect power. Unplug tool when not in use.  
12. Remove adjusting keys and wrenches. Check that keys and adjusting  
wrenches are removed from the tool or machine work surface before plugging  
it in.  
13. Avoid unintentional starting. Be sure the switch is in the Off position when  
not in use and before plugging in.  
14. Stay alert. Watch what you are doing, use common sense. Do not operate  
any tool when you are tired.  
15. Check for damaged parts. Before using any tool, any part that appears  
damaged should be carefully checked to determine that it will operate properly  
and perform its intended function. Check for alignment and binding of moving  
parts; any broken parts or mounting fixtures; and any other condition that may  
affect proper operation. Any part that is damaged should be properly repaired  
or replaced by a qualified technician. Do not use the tool if any switch does not  
turn On and Off properly.  
16. Guard against electric shock. Prevent body contact with grounded surfaces

18. Do not operate tool if under the influence of alcohol or drugs. Read warning  
labels on prescriptions to determine if your judgment or reflexes are impaired  
while taking drugs. If there is any doubt, do not operate the tool.  
19. Use proper size and type extension cord. If an extension cord is required, it  
must be of the proper size and type to supply the correct current to the tool  
without heating up. Otherwise, the extension cord could melt and catch fire, or  
cause electrical damage to the tool. If you are using the tool outdoors, use an  
extension cord rated for outdoor use (signified by “WA” on the jacket).  
20. Maintenance. For your safety, service and maintenance should be performed  
regularly by a qualified technician.  
Note: Performance of this tool (if powered by line voltage) may vary depending on  
variations in local line voltage. Extension cord usage may also affect tool perfor-  
mance.  
Warning:The warnings, cautions, and instructions discussed in this instruc-  
tion manual cannot cover all possible conditions and situations that may oc-  
cur. It must be understood by the operator that common sense and caution  
are factors which cannot be built into this product, but must be supplied by  
the operator.  
Grounding/VoltageWarning  
Warning: Before using this tool, make sure that the power cord will be plugged  
into an outlet which has a three-prong ground, is 120V AC, is protected by a  
30 Amp circuit breaker and has a Ground Fault Interrupter.  
Common household current is 110-120V. As long as the outlet used with the Tile  
Saw is rated from 110-120V there will be no complications using it with house-  
hold receptacles. Plug the tool into a 110-120V properly grounded outlet pro-  
tected by a 15-Amp, dual element time delay or circuit breaker.  
NEVER try to plug a 110-120V tool into a 220-240V circuit, or serious complica-  
tions and possible injury to the operator may occur. The plugs have different  
shapes to prevent this.  
This tool has a three-prong plug. The third round prong is the ground. Cutting off  
the ground will result in a safety hazard and void the warranty.  
If the outlet you are planning to use is the two-prong type, do not remove or alter  
the grounding prong in any way. Use an adaptor and always connect the ground-  
ing lug to a known grounding source. It is recommended that you have a qualified  
electrician replace the two-prong outlet with a properly grounded three-prong  
outlet.

Extension Cords  
Your tool has a three-prong plug, therefore you must use a three-prong extension  
cord. Only use rounded jacket extension cords listed by the UL. Improper use of  
extension cords may cause inefficient operation of your tool which can result in  
overheating. Be sure your extension cord is rated to allow sufficient current flow to  
the Motor. If you are using the tool outdoors, use an extension cord rated for out-  
door use (signified by “WA” on the jacket).  
Unpacking  
When unpacking, check to make all parts listed on Pages 10-11 are included. If any  
parts are missing or broken, please call Harbor Freight Tools at the number on the  
cover of this manual.  
Note: Table Stand SKU #46310 is specifically designed for use with this 10” Tile  
Saw and is not included. Stand is available for purchase from Harbor Freight Tools.  
See Fig. 1 on Page 9 for a view of the Table Saw and Stand assembly.  
If the Stand is not to be used with the Tile Saw, the Saw must be securely mounted  
onto a flat, level surface capable of supporting the weight of the Tile Saw in addition  
to the weight of all work pieces.  
Assembly  
1. Slide the Water Tank [1] through the slots in the Machine Frame [6] so that the  
entire Tank rests inside the Machine Frame.  
2. Mount the Motor [19] to the Machine Frame by connecting the Supporting  
Frame [12] to the Machine Frame at the point shown in the Assembly Diagram  
on Page 12. Secure using two Bolts [7], Elastic Washers [8] and Big Flat  
Washers [9] as shown.  
3. Next, attach the Blade Guard [20] to the Motor using the Locking Knob [23]  
and Flat Washer [24] provided. Please note: this product does not include a  
Blade. Please see the following section, “Changing/Installing the Blade,” for  
instructions on how to properly install a new Blade.  
REV 08/04  
SKU 46225 For technical questions, please call 1-800-444-3353.

4. Plug the Pump [59] into the back of the Motor and attach the Pump to the  
WaterTank using the four suction feet on the bottom of the Pump. See Fig. 2 on  
Page 11.  
5. Slide the Table Holder [51] through the middle of the Rail Cover [47] and fit the  
two Inserts [45] over the ends of the Cover to prevent the Table Holder from  
slipping out.  
6. Attach the Rail and Table [52] Assembly you created in Step 5 to the Frame  
using two sets of the Bolts [3], Flat Washers [4] and Teeth Washers [5] as  
shown in the Assembly Diagram.  
7. Before operating this tool, mount theTable Saw to theTable Stand (SKU #46310,  
sold separately) by following the steps outlined in the Assembly and Operating  
Instructions for the Table Stand. If the Stand is not to be used with the Tile Saw,  
the Saw must be securely mounted onto a flat, level surface capable of  
supporting the weight of theTile Saw in addition to the weight of all work pieces.  
Changing/Installing the Blade  
1. Be sure the Power Cord is unplugged from its power source.  
2. Loosen the Locking Knob located on the side of the Blade Guard [20] and  
raise Guard. Tighten the Knob to lock the Guard in an “up” position.  
3. Depress the Brake Shaft Button [26] (See Fig. 1 on Page 10) while turning the  
Blade (or Spindle [44] if you have not yet installed a Blade) with your hand until  
the Shaft button depresses fully. This will prevent the Spindle from spinning  
and allow you to unscrew the Nut [29] and Outer Flange [30].  
4. Slide the new Blade over the Spindle, and refasten the Outer Flange and Nut.  
Be sure to tighten the Nut fully before use.  
5. Lower the Blade Guard and tighten the Locking Knob.  
Installing the Water Supply  
To prevent excessive wear on the Blade, be sure to maintain a continuous flow of  
water over the Blade while cutting. Never cut anything if the water flow is not con-  
tinuous.  
1. Attach the Pump as described in Step 4, “Assembly.” Position the Pump so it  
will not interfere with the motion of the Table while cutting.  
2. Fill the Water Tank with enough water so that the Pump is completely  
submerged, but not so much water that the Tank overflows.  
Note:When using theTile Saw, extreme care must be taken to insure that the  
Saw’s Power Cord is positioned to remain dry and free from water at all times.  
Severe personal injury or death can occur if the Power Cord or the operator of  
this tool should become wet at any time while this tool is in use. Care and  
common sense must be used in planning a safe work area.  
SKU 46225 For technical questions, please call 1-800-444-3353.

Operation  
Preparing to Cut:  
1. Mark the tile you wish to cut and place it aside for a moment.  
2. Fill the Tank with water as described in “Installing the Water Supply,” above.  
3. Plug the Pump’s Power Cord into the Power Unit. Make sure the Pump Power  
Cord is positioned so it will remain in a dry location once the machine is in use.  
If an extension cord is used, make sure it is of appropriate size and length  
-see Recommended Minimum Wire Gauge for Extension Cords page 5.  
4. When it is safe to do so, plug the Power Unit Cord into an appropriate outlet.  
5. Put on your ANSI-approved eye protection.  
6. Flip the Power Switch located on the front of the Motor (see Fig. 2 on Page 11)  
to the “on” position.  
7. Before operating the Tile Saw, let the Motor run for approximately one minute.  
Make sure the Blade is rotating at full speed and there are no unusual noises.  
If you feel the unit is not operating properly, do not use this tool.  
8. To keep the pump working properly, the water in the tub may need to be  
changed in the middle of a long project. Never allow the water to become  
muddy or full of silt. When changing the water, always rinse out the intake of  
the pump in clean water to help prevent silt buildup.  
9. When finished, flip the power switch to theoffposition, unplug the unit, dispose  
of the dirty water in an appropriate manner, rinse the pump’s inlet, and clean  
any silt out of the bottom of the tank.  
Cutting Tile:  
1. Place your marked tile on the Table and brace it against the upturned edge  
(Fence) on the back of the Table. Align the cut mark with the Blade.  
2. Once the Tile Saw has been turned on, allow the Blade to spin up to full speed.  
Watch to be sure that the Pump is supplying a continuous flow of water to the  
Blade.  
3. Keeping your hands clear of the Blade, move the Table and the tile underneath  
the Blade. Feed the tile underneath the Blade very slowly. Do not force it. If the  
rotational speed of the Blade slows down significantly, then you are forcing the  
tile. No spectators should be allowed in the working area.  
4. While cutting, watch to be sure that the Blade remains wet. If it runs dry, check  
the action of the Pump and the Water level of the Tub.

5. If the Motor stops suddenly, flip the Power Switch to the “off” position. Wait  
approximately 15 minutes, remove the Circuit Breaker Cap located directly  
above the Power Switch, and push the Reset Button.  
Using the Parallel Guide:  
If you have to cut a number of tiles to the same dimension, using the Parallel Guide  
may save you a significant amount of time.  
1. Mark the first tile to the correct dimensions, allowing space for grout.  
2. With the Motor turned off, place the marked tile on theTable against the Fence.  
Align the cut mark with the Blade.  
3. Loosen the Locking Knob [23] on the Parallel Guide [57]. Place the hooked  
portion of the Guide over the upturned edge of the Table, on the side of the  
cutting groove where you have placed the part of the marked tile that you  
intend to keep and use after cutting. The Parallel Guide will be parallel to the  
tile, and perpendicular to the Fence.  
4. Slide the Parallel Guide along the Fence until it abuts the tile, keeping sure that  
the mark on your tile remains in line with the Blade.  
5. Tighten the Locking Knob on the Parallel Guide.  
6. When you are satisfied that the tile is aligned with the Blade, and the Guide is  
in place, and it is safe to do so, turn on the Power Switch.Cut the tile as described  
in previous instructions.  
7. Check to be sure that the tile has been cut to the proper dimensions before  
using the Parallel Guide to cut your other tiles. Periodically test the fit of each  
tile as you continue cutting, to be sure the Parallel Guide has not moved.  
Using the Angle Guide:  
Use the Angle Guide for cutting angled edges on your tiles.  
1. Attach the Angle Guide [58] to the Fence as you did the Parallel Guide, using  
the two Locking Knobs [23] to hold the Guide in place.  
2. Use the Cutting Groove in the middle of the Table to brace the edge of your tile  
as you slide the tile and the Table underneath the Blade.  
Maintenance  
Always unplug the Power Cord before servicing and before performing any  
maintenance.  
General Maintenance:  
1. Regularly inspect the Diamond Saw Blade. Using a dull Blade will cause  
excessive wear on the Motor, and will not produce a satisfactory cut. Replace  
with a new one when needed.  
SKU 46225 For technical questions, please call 1-800-444-3353.  
Page 8  
 
2. Inspect the Mounting Screws on all safety covers, and the Arbor Nut on the  
Cutting Wheel Shaft. Tighten any that appear loose.  
3. Protect the Motor and electrical components from prolonged or excessive  
exposure to water or wet conditions. Wipe the unit dry as needed.  
4. Periodically apply a light lubricant to the Rail Cover.  
5. Note: The Pump is non-serviceable. If it should fail, first try clearing the intake  
of debris and be sure the hole is not plugged.  
6. To clean the Pump Filter, remove the front cover and impeller. See Figure A.  
7. Ue a small brush or stream of water to remove any debris.  
8. If the Pump is used on a dirty surface, raise it slightly to reduce the amount of  
debris entering the intake.  
9. Adjust the Flow Control on the end of the Pump to restrict flow.  
10. Do not let the Pump run when it is not submerged in water. Running the Pump  
out of the water will damage the Pump.  
11. If the Pump still does not work, it must be replaced. Replacement Pumps are  
available through Harbor FreightTools.
