4. Use Wall and Floor tiling tools and equipment 1 Identify hand and power tools . Power tools Electricity can be dangerous and care should be taken in its use. Even if you have worked in the industry a long time or feel you know about electrical safety, do not take risks with electricity. To prevent accidental electrocution, always use earth leakage circuit breakers (ELCBs) Before power tools are used , operators must be given extensive instruction in the safe use of each power tool to be used Figure 5.4 -Earth Leakage Circuit Breaker (ELCB) As part of the Wall and Floor Tiling Trade course, students will be instructed in the safe use of numerous power tools, including: Basic electrical safety Earth Leakage Circuit Breakers (ELCBs) Extension leads Drills Rotary hammer Figure 5.4-Earth Leakage Circuit Breakers (ELCBs)
5. Use Wall and Floor tiling tools and equipment 1 Select tools for project There are many other tools that a tiler may need to carry out wall and floor tiling. Specific tasks may require the use of special tools that can be purchased as needed.

20. Use Wall and Floor tiling tools and equipment 1 Use tools General procedure for hand cutting dust-pressed tiles The glaze of the tile is cut or scored by drawing the cutting tool firmly across the glaze (once should be all that is needed). This then becomes a weak point in the glaze and when pressure is applied by placing that line on a nail (or similar) and exerting a firm downward pressure, the tile will break along that line. Ascertain the size needed, either by measuring the area where the cut is going or by putting the tile on the space and marking the tile directly. After the tile has been marked, place a guide on that mark. Draw the cutter firmly along the guide, once only should be enough. Place the line of the cut over a nail (or similar object). Place the base of the thumbs (or the top of the thumbs if the cut is small) on either side of the cut or apply steady, downward pressure. Rub down the edges of the cut (if necessary) with carborundum block, (or similar). If a number of tiles are to be cut at the same size use one tile as a * template and cut the rest on a * gauge board .

Take extra care when getting near the finish marks. When cutting around taps you should leave a small gap so the tap bodies can be removed for servicing.
30. Use Wall and Floor tiling tools and equipment 1 Cutting tiles with manual tile cutting machines Dust pressed wall tiles are easily cut by scribing the glazed surface with a tungsten carbide tipped cutter and snapping the tile either by hand or placing the scribe mark over some sort of raised section placed under the tile.
