Keep your body positioned to either side of the wheel, but not in line with the wheel. It is important to support the tool properly and to position your body such as to minimize body exposure from possible wheel binding and recoil. 3. Grip the tool firmly while cutting and always be ready and able to manage the cut. 4. Avoid jamming, twisting or pinching the wheel with the workpiece of otherwise applying excessive side pressure to the wheel. CUTTING TILE Make sure material being cut is secured in a vise or fixture before attempting to cut. Turn the tool on and wait for the wheel to reach full speed. For cuts that extend to the edge of a tile, cut all the way through edge(s) along your cut line. Score the tile first along your cut line, making multiple passes to progressively cut through the tile. accessory has come to a complete stop. This tool does not use wheels designed for face-grinding. If your cut requires a smooth, 1. Make sure material being cut is secured in a finished edge, use an appropriate tile finishing vise or fixture before attempting to cut tool to refine the tile edge. PLUNGE OR INTERIOR CUTS The size and versatility of the Dremel SM20 make it an excellent option for making plunge or interior cuts into a workpiece such as flooring, paneling, or siding. 1. Mark the surface to be cut with the desired cut lines 2. Loosen the Depth Adjustment Lever so that the spring loaded foot releases and goes to the zero depth setting. Leave the Depth Adjustment Lever loose during this cut. 3. Rest the Foot of the tool on the workpieces and Align the tool’s wheel with the cut line (Fig. 8). 4. While holding the tool firmly, Press the Paddle Switch and allow the tool’s wheel to come up to full speed. 5. Slowly plunge/lower the tool and wheel into the workpiece (Fig. 9). 6. Guide the tool forward and complete the cut 7. Release the Paddle Switch and allow the tool to come to a complete stop. 8. Remove the tool from the workpiece. 9. Repeat steps 3-8 as required to complete your cuts.

For flooring installation, add up the thickness of your flooring adhesive, the flooring itself, and any underlayments or other material that will add to the thickness of the finished floor. 1. Install the flush cutting wheel on the tool as described in “Flush Cutting Wheel Assembly”, page 10. 2. Adjust the depth of the wheel to the desired depth setting. 3. Turn the tool on it’s side so that the flush cut foot rests against the flooring. 4. Firmly grip the tool. Turn tool on and allow it to come to full speed before entering workpiece. CUTTING LARGE SHEETS Large sheets and long boards sag or bend, depending on support. If you attempt to cut without leveling and properly supporting the piece, the wheel will tend to bind, causing KICK- BACK and extra load on the motor (Fig. 11). Support the panel or board close to the cut, as shown in (Fig. 12). Be sure to set the depth of the cut so that you cut through the sheet or 5. Complete your cut and remove the tool from the workpiece before turning the tool off. FIG. 10 board only and not the table or work bench. The two-by-fours used to raise and support the work should be positioned so that the broadest sides support the work and rest on the table or bench. Do not support the work with the narrow sides as this is an unsteady arrangement. If the sheet or board to be cut is too large for a table or work bench, use the supporting two-by-fours on the floor and secure.
