• Wear safety goggles or face shield to protect yourself from flying chips.
• Wear hearing protection that is suitable for the level and frequency of the noise you are exposed to in the
woodworking area.
• Wear a dusk mask when dust is generated (e.g., during sanding operations).
• Work in well-lighted area.
• Before the lathe is turned on, ensure that all clamps and fittings are secure and that the work piece is free to turn.
• Use stock free of defects.
• Hold tools firmly with both hands and against the tool rest.
• Hold the stock securely on the faceplate or between the centres.
• Use only furnished or approved tools.
• Use sharp, well-maintained chisels and gouges.
• Select a speed that is appropriate for the job. Operate the lathe at a low speed and use a moderate cut depth to
prevent splinters from flying out during roughing operations. The actual speed of the lathe depends on type of
wood, a diameter of stock, nature of work being done and type of tool used.
• Adjust tool rests so that they are parallel and as close as possible to the stock. They should also be set high enough
so that tools will cut into the wood slightly above the centre of the work being turned.
• Remove the tool rest when sanding or polishing.
• Use appropriate tools to hold the sand paper or emery paper whenever possible. Examples include a 'nut cracker'
or the paper fixed to a piece of flat wood. If you must use your hands always hold the paper in a way that will
allow the paper to catch, pull or entangle around the stock.
• To make a faceplate turning, the one hand steadies the tip of the chisel, which holds the edge against the tool rest
while the other hand guides the tool. Keep the tip of the chisel held higher than the handle.
