Checking the Sharpener Shoes
The shoes should swing in and out freely without excessive
up and down play . If adjustment is necessary, proceed as
follows:
1. Loosen the locknuts (Figure 6, 3) and tighten the screws
(Figure 6, 7) as required.
Checking the Extreme Down Position of the Sharpener
The correct down position is with the tip of the knife at the
center of the belt on the shoe (Figure 6, 12). The belt should
be in the most downward position, and the knife should be
in the most upward position. If the belts are too high, the
bottom point of the knife will not sharpen. If the belts are
too low, the bottom point of the knife will round off excessively. If adjustment is necessary:
1. Raise the belt carrier to the up position.
2. Remove the plastic cap from the tube for the screw
shaft.
3. Insert a pin through the hole in the tube (Figure 6, 13) to
prevent the spacer (Figure 6, 14) from turning. Then
remove the locknut (Figure 6, 15).
The following step describes the correct procedure for
setting spacer adjustment on different stroke machines:
Note: Prior to beginning adjustment, be sure that the
spacer is threaded fully onto screw shaft.
Stroke Turns
2. Check the clamping arm (Figure 6, 10) with the belt
carrier in the most downward position and the knife in the
most upward position. The clamping arm should keep
the sharpener shoe from moving in. If it fails to do so,
the serrations on the clamping arm are worn or the
sharpener shoe (Figure 6, 11) is worn.
3. Replace worn part(s) as necessary.

Note: Each turn = 1/32"
4. Turn the spacer clockwise with wrench C6153 to raise
the bottom position, or turn counter-clockwise to lower
the position.
Note: One turn in either direction adjusts the position
by 1/32".
