GENERAL SAFETY PRECAUTIONS AND HAZARD SYMBOLS In order to prevent injury, the following safety precautions and symbols should be followed at all times! Safety Precautions ALWAYS read this Owner s Manual before operating the machine. ALWAYS keep the Blade Guards in place. REMOVE ADJUSTING KEYS AND WRENCHES Form a habit of checking to see that keys and adjusting wrenches are removed from the power tool before it is turned on. KEEP WORK AREA CLEAN Cluttered work areas and benches invite accidents. DO NOT USE IN DANGEROUS PLACES DO NOT use power tools in damp or wet locations nor expose them to rain. Always keep the work area well lighted. KEEP CHILDREN AWAY All visitors and children should be kept a safe distance from work area. 4
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. 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 line voltage that will result in a loss of power and overheating. TABLE 1, Page 10 shows the correct AWG size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord. USE PROPER APPAREL DO NOT wear loose clothing, gloves, neckties, rings, bracelets, or other jewelry that may be caught in moving parts. Non-slip footwear is recommended. Wear protective hair covering to contain long hair. ALWAYS wear approved eye protection. ALWAYS wear approved respiratory protection. SECURE WORK Clamps or a vise should be used to hold work whenever practical. Keeping your hands free to operate a power tool is safer. DO NOT OVERREACH Keep proper footing and balance at all times by not overreaching. MAINTAIN TOOLS WITH CARE Keep tools clean for the best and safest performance. Always follow maintenance instructions for lubricating, and when changing accessories. 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. 5
SAFETY Hazard Symbols ELECTRICAL SHOCK NEVER touch electrical wires or components while the engine is running. They can be sources of electrical shock which could cause severe injury or burns. ROTATING PARTS Keep hands, feet, hair, and clothing away from all moving parts to prevent injury. Never operate the motor with covers, shrouds, or guards removed. (( )) OVER SPEED NEVER tamper with the governor components or settings to increase the maximum speed. Severe personal injury and damage to the engine or equipment can result if operated at speeds above maximum. DO NOT EXPOSE TO RAIN DO NOT expose to rain or use in damp locations. WARNING Sawing and drilling generates dust. Excessive airborne particles may cause irritation to eyes, skin and respiratory tract. To avoid breathing impairment, always employ dust controls and protection suitable to the material being sawed or drilled; See OSHA (29 CFR Part 1910.1200). Diamond Blades improperly used are dangerous. Comply with American National Standards Institute Safety Code, B7.1 and, Occupational Safety and Health Act covering Speed, Safety Guards, Flanges, Mounting Procedures, General Operating Rules, Handling, Storage and General Machine Conditions WARNING Diamond Blades improperly used are dangerous. Comply with American National Standards Institute Safety Code, B7.1 and, Occupational Safety and Health Act covering Speed, Safety Guards, Flanges, Mounting Procedures, General Operating Rules, Handling, Storage and General Machine Conditions 6
SAFETY USE RECOMMENDED ACCESSORIES Consult the owner s manual for recommended accessories. Using improper accessories may increase the risk of personal or by-stander injury. NEVER STAND ON THE TOOL Serious injury could occur if a power tool is tipped, or if a cutting tool is unintentionally contacted. CHECK FOR DAMAGED PARTS Before using a power tool, check for damaged part. A guard or any other part that is damaged should be carefully checked to determine if would operate properly and perform its intended function. Always check moving parts for proper alignment or binding. Check for broken parts and mountings and all other conditions that may affect the operation of the power tool. A guard, or any damaged part, should be properly repaired or replaced. DIRECTION OF FEED ALWAYS feed work into a blade or cutter against the direction of rotation. A blade or cutter should always be installed such that rotation is in the direction of the arrow imprinted on the side of the blade or cutter. NEVER LEAVE A TOOL UNATTENDED TURN POWER OFF - Do not leave a tool until it comes to a complete stop. Always turn a power tool OFF when leaving the work area, or, when a cut is finished. CALIFORNIA PROPOSITION 65 MESSAGE WARNING Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contain chemicals known (to the State of California) to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are: Lead, from lead-based paints Crystalline silica, from bricks and cement and other masonry products Arsenic and chromium, from chemically treated lumber For further information, consult the following sources: http://www.osha.gov/sltc/silicacrystalline/index.html http://www.cdc.gov/niosh/consilic.html http://oehha.ca.gov/prop65/law/p65law72003.html http://www.dir.ca.gov/title8/sub4.html Your risk from these exposures varies depending on how often you do this type of work. To reduce your exposure to these chemicals, work in a well-ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles. 7
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. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances. Do not modify the plug provided if it will not fit the outlet; have the proper outlet installed by a qualified electrician Improper connections of the equipment-grounding conductor can result in a risk of electric shock. The equipment-grounding conductor is the insulated conductor that has an outer surface that is green, with or without yellow stripes. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the tool s plug Repair or replace a damaged or worn cord immediately WARNING This tool is intended for use on a circuit that has an outlet that looks like the one shown in Sketch A. The tool has a grounding plug that looks like the plug illustrated in Sketch A. A temporary adapter, which looks like the adapter illustrated in sketches B and C, may be used to connect this plug to a 2-pole receptacle as shown in Sketch B, if a properly grounded outlet is not available. The temporary adapter should be used only until a properly grounded outlet can be installed by a qualified electrician. The green-colored rigid ear, lug, and the like, extending from the adapter, must be connected to a permanent ground such as a properly grounded outlet box. NOTE: Use of a temporary adapter is not permitted in Canada.

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, shown in the picture below, 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. This method of positioning the cord prevents the travel of water along the power cord and coming in contact with the receptacle. If the plug or receptacle gets wet, DO NOT unplug the cord. Disconnect the fuse or circuit breaker that supplies power to the tool. Then unplug and examine for presence of water in the receptacle. Power Cord Power Tool Supporting Surface Drip Loop Drip Loop Information WARNING Use only extension cords that are intended for outdoor use. These extension cords are identified by a marking Acceptable for use with outdoor appliances; store indoors while not in use." Use only extension cords having an electrical rating not less than the rating of the product. Do not use damaged extension cords. Examine extension cords before using and replace if damaged. Do not abuse extension cords and do not yank on any cord to disconnect. Keep cords away from heat and sharp edges. Always disconnect the extension cord from the receptacle before disconnecting the product from the extension cord. 9
SAFETY WARNING To reduce the risk of electrocution, keep all connections dry and off the ground. Do not touch the plug with wet hands. 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. Once the proper length is found, move down the column to obtain the correct AWG size required for that length of extension cord.
