  • Page 41 Model W1678 (For Machines Mfd. Since 02/24) Note: Sanding drum should touch gauge blocks and still be able to rotate with moderate force. Drum should touch both gauge blocks with equal resistance on both sides. — If drum is aligned equally on both gauges, no adjustment is necessary.
  • Page 42 Model W1678 (For Machines Mfd. Since 02/24) 8. Lower table two full turns, then position gauge blocks under rear drum. 9. Slowly raise table to height referenced in Step 7. Note: If either gauge block touches sanding drum before reaching reference mark, rotate micro- adjustment knobs clockwise to raise rear sanding drum out of the way.

  • Page 43: Adjusting Pressure Roller Height & Tension

    Model W1678 (For Machines Mfd. Since 02/24) Adjusting Pressure Roller Height & Tension Proper pressure on the workpiece helps avoid kickback and keeps the workpiece from slipping.
