drive belt. If, however, it becomes necessary to adjust
the belt, follow the steps listed below:
1. Remove belt as previously instructed.
2. Move control lever to the highest apron speed
position.
3. Check upper sheaves (A), if base of sheaves are
not tight together, it is necessary to adjust.
4. Remove bolt from control rod (B).
5. Slide sheaves tight together, being sure control
yoke (C) is tight against thrust bearing and
sheaves.
6. Adjust control rod (B) so hole in control yoke and
rod align, then one additional turn.
7. Replace bolt. Allow sufficient play when tightening,
so control rod pivots.
