Replacing the Rubber Driver Pulley
The sharpener is driven by a rubber driver pulley, as shown
in Figure 2. Replace this driver pulley whenever it appears
to be worn or damaged, as follows:
1. Remove the sharpener from the machine (see Remov-
ing the Sharpener on page 3).
2. Press the sharpener lever (Page 3, Figure 1, K) to a
neutral position and lower the sharpener until an inch
of the square shaft (Figure 2, W) is exposed.
3. Hold the square shaft with a wrench. Position the
wrench as close as possible on the shaft to the sharp-
ener housing.
4. Use a spanner wrench to remove the driver pulley
by turning it clockwise as indicated by the arrow in
Figure 2.
Note: The pulley has a left-hand thread.
5. Reassemble the new pulley on the sharpener.
6. Reassemble the sharpener on the machine.
