General Safety Rules

When using electric tools basic safety precautions should always be followed to reduce the risk of fire, electric shock and personal injury.

• Keep guards in place and in working order.

• Remove adjusting keys and wrenches. Form the habit of checking to see that keys and adjusting wrenches are removed from the machine before turning it on.

• Keep the working area clean. Cluttered areas and benches invite  accidents.

• Don’t use in a dangerous environment. Don’t use power tools in damp or wet locations, or expose them to rain.

• Keep work area well lighted.

• Keep children away. All visitors should be kept at a safe distance from the work area.

• Make your workshop kid proof. Lock your workshop. Tools not used should be kept in a dry place, inaccessible for children.

• Don’t force the tool. It will do the job better and safer at the rate for which it was designed.

• Use the right tool. Don’t force the tool or attachment to do a job for which is was not designed.

• Use proper extension cord. Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in voltage resulting in loss of power and overheating.

• Wear proper clothing. Do not wear loose clothing, gloves, neckties, rings, bracelets, or other jewelry which may get caught in moving parts. Nonslip shoes are recommended. Wear protective hair covering to contain long hair. Roll your sleeves up to above the elbows.

• Protect your eyes by safety goggles. Everyday eyeglasses offer only little protection. They are no safety glasses. Wear a face or dust mask when working in a dusty environment.

• Secure work. Use clamps or a vice to hold work, when practical. It is safer than using your hand, and it frees both hands to operate the tool.

• Don’t overreach. Keep proper footing and balance at all times.

• Maintain tools with care. Keep tools sharp and clean for best and safest performance. Follow the instructions for lubricating, and changing accessories.

• Always disconnect the machine before servicing, and when changing accessories, such as blades, bits, cutters, and the like.

• Only use recommended accessories. Consult the operating instructions for the recommended accessories. The use of improper accessories may cause risk of injury to persons.

• Never stand on the machine. Serious injury could occur if the machine is tipped or if the cutting tool is unintentionally contacted.

• Check for damaged parts. Before further use of the tool, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment or binding of moving parts, breakage of parts, mounting, and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced.

• Direction of work. Push the workpiece towards the sawblade or cutter only in the moving direction of the tool.

• Never leave the machine unattended while it is running. Wait until the tool has come to an absolute standstill, before you leave the machine.

• Use the correct power connection. Do not pull the power plug to stop the machine during work. Never remove the plug from the socket by pulling the extension cord.

• Always stay attentive to what you are doing, even when using the machine regularly. Bear in mind that a fraction of a second is sufficient to cause an injury.

• Keep your safety in mind. Safety is a combination of common sense and staying alert as long as the machine is switched on.
  Additional safety rules for the belt and disc sanding machine
