MAINTENANCE

Replacing or Changing Grinding Wheels

Disconnect the machine from the power source.

For steps 1-4, refer to Figures 4 & 5 on page 10:

1.Remove the thumb screws securing the outer face of the wheel guard to the tool frame.

2.Rotate the wheel guard to free it from the retaining screws and remove guard.

3.Raise both wings of the arbor nut.

4.Firmly grasp the wings of the arbor nut with one hand while using the other hand to keep the wheel from moving. Loosen the arbor nut.

NOTE: You may also use the 13mm flat wrench (provided) positioned on the flat of the arbor shaft, (located between left side wheel and motor) to keep the shaft steady as you tighten the arbor nut.

NOTE: To loosen the arbor nut on the right side rotate it counterclockwise. To loosen the arbor nut on the left side rotate it clockwise.

5.Remove the arbor nut (A), wheel flange (B), and old grinding wheel (C), as shown in Figure 10.

6.Place the new grinding wheel on the arbor.

NOTE: Grinding wheels for the 23-198 must be ¾" wide while grinding wheels for the 23-199 must be 1" wide.

7.Place the flange on the arbor and thread the arbor nut on the arbor until the arbor nut makes contact with the arbor flange.

8.Tighten the arbor nut as tight as you can by hand.

9.Push the arbor nut wings out and down to the closed position so that they lay flat against the thick wheel flange.

10.Replace the wheel guard and secure with thumb screws.

Other Recommended Maintenance

1.Periodically blow out all air passages with dry compressed air. All plastic parts should be cleaned with a soft damp cloth. NEVER use solvents to clean plastic parts. They could possibly dissolve or otherwise damage the material.

2.Periodically inspect the tightness of the arbor nuts.

3.Periodically check tightness on all other hardware and listen for any unusual vibrations as you work as these may be a sign of loose hardware.
