Important Safety Information
1. Assemble only according to these instructions.  
Improper assembly can create hazards.
2. Wear ANSI-approved safety goggles 
and heavy-duty work gloves 
during assembly and use.
3. Keep assembly area clean and well lit.
4. Keep bystanders out of the 
area during assembly.
5. Do not assemble when tired or when under 
the influence of drugs or medication.
Assembly Instructions
1. Insert the threaded end of the Breaking 
Bar (21) into the Connector (17). 
Operating Instructions
1. Mark the cut line on the tile with 
a soft carpenter’s pencil. 
2. Loosen the Try Square Knob (23) and slide 
the Try Square out so there is room for the tile.
3. With the glazed side up, place the tile 
against the Ruler Bar (7), with the pencil 
line directly under the Cutting Wheel (16).
4. Slide the Try Square to the edge of the 
tile and tighten the Try Square Knob. 
Note: Once the Try Square is secured at the 
desired setting, you can make multiple cuts of the 
same size without marking the cut line on the tile.
6. This product is not a toy. Do not allow 
children to play with or near this item.
7. Use as intended only. Do not use 
handle extension to increase force.
8. Inspect before every use; do not use 
if parts are loose or damaged.
9. Maintain product labels and nameplates.  
These carry important safety information.  
If unreadable or missing, contact 
Harbor Freight Tools for a replacement.
2. Screw the Knob (22) clockwise onto the 
Breaking Bar until it is tightly in place. 
5. Holding the tile firmly, score along 
the pencil line with the Cutting Wheel 
several times across the pencil line.
6. Raise the Breaking Bar (21), and 
position the tile so that the front edge 
of the pencil line is lined up with the 
center of the Breaking Foot (20). 
7. Holding the Knob (22), press down firmly to 
split the tile along the scored pencil line.
Note: The scoring action occurs by moving 
the Carriage (14) from the back to the front 
each time and pressing down slightly. At the 
end of the motion, raise the Breaking Bar, 
and move it backwards. Repeat this action 
several times, depending on the thickness 
of the tile, until a scored line appears.
