    § 8 MAINTENANCE 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 103 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.
