NEVER STAND ON THE TOOL Serious injury could occur if a power tool is tipped, or if a cutting tool is unintentionally contacted.

  • Page 8: Electrical Requirements And Ground Instructions

    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 cur- rent to reduce the risk of electric shock.
  • Page 9 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.
  • Page 10 MK-1280 ELECTRIC SAW 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.

Over time and use, diamonds on the outer edge will become smoothed or “glazed” over. This will reduce grinding efficiency and may cause the blade to “wander” or bend giving the illusion of an alignment problem.
