SDG Safety MAKE THE WORKSHOP KID PROOF Make the workshops kid proof by using padlocks, master switches or by removing starter keys. DO NOT FORCE THE TOOL A power tool will do a job better and safer operating at the rate for which it was designed. USE THE RIGHT TOOL DO NOT force a tool or an attachment, to do a job that it was not designed to do. USE THE PROPER EXTENSION CORD If using an extension cord make sure it is in good condition first.
SDG Safety DISCONNECT TOOLS Power tools should always be disconnected before servicing or when changing accessories, such as blades, bits, cutters, and the like. ON / OFF ALWAYS place the power ON/OFF switch in the OFF position when the saw is not in use. USE RECOMMENDED ACCESSORIES Consult the owner’s manual for recommended accessories. Using improper accessories may increase the risk of personal or by-stander injury.
SDG Safety SILICA DUST WARNING Grinding/cutting/drilling of masonry, concrete, metal and other materials with silica in their composition may give off dust or mists containing crystalline silica. Silica is a basic component of sand, quartz, brick clay, granite and numerous other minerals and rocks. Repeated and/or substantial inhalation of airborne crystalline silica can cause serious or fatal respiratory diseases, including silicosis.
SDG Safety ELECTRICAL REQUIREMENTS AND GROUNDING INSTRUCTIONS In order to prevent potential electrical shock and injury, the following electrical safety precautions and symbols should be followed at all times! WARNING In case of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment-grounding conductor and a grounding plug.
SDG Safety WARNING To avoid the possibility of the appliance plug or receptacle getting wet, position the machine to one side of a wall mounted receptacle. This will prevent water from dripping onto the receptacle or plug. A “drip loop,” should be arranged by the user to properly position the power cord relative to the power source. The “drip loop” is that part of the cord below the level of the receptacle, or the connector, if an extension cord is used.
SDG Safety WARNING Use of under sized extension cords result in low voltage to the motor that can result in motor burnout and premature failure. MK Diamond warns that equipment returned to us showing signs of being run in a low voltage condition, through the use of undersized extension cords will be repaired or replaced totally at the customer's expense. There will be no warranty claim. To choose the proper extension cord, • Locate the length of extension cord needed in the table below.
SDG Safety OPERATION & SAFETY DECALS The SDG is equipped with a number of safety decals. These decals are provided for operator safety and maintenance information. Should any of these operation or safety decals become unreadable, replacements can be obtained by calling (800) 262-1575.
