    SAFETY § 2 In this manual, Signal Words are used to designate a degree or level of safety alerting, whose definitions are as follows. Indicates a potentially hazardous situation which, if not avoided, WARNING: could result in death or serious injury. CAUTION: Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury or property damage accident.
  • Page 10 2 - 2 CAUTION • Never disassemble nor touch the internal structure. Electric shock or failure of the instrument may occur. • Never yank the power cord to disconnect it from the wall outlet. Always hold the plug. This can damage the metal core of the cord and may result in fire, short circuit or electric shock.

    MAINTENANCE § 8 8.1 Wheel Dressing A clogged wheel requires a longer time for processing and makes the finished size inaccurate. It is necessary, therefore, to regularly dress the wheels. CAUTION • In the dressing mode, the cover sensor is released and the wheels turn with the soundproof cover open.
  • Page 102 8 - 2 3. Open the soundproof cover. 4. Start dressing. CAUTION • Apply the end surface of the dressing stick to the wheel, not the corner or the edge. Otherwise, the wheel may be damaged. • Hold the dressing stick with both hands. If the stick is held with one hand, the stick cannot be held strongly enough, the corner of the stick may collide with the wheel and damage it.
