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.

MK-SDG Safety n 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.
MK-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.
MK-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,” 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.
MK-SDG 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.
