VARIABLE SPEED BELT ADJUSTMENT
ADJUSTMENT
You should rarely have to adjust the variable speed
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.
8. Place control lever in beater disengage position
and replace belt.

OIL
LEVEL
The operator should become familiar with all lubrica-
tion points and establish a systematic routine to insure
complete and quick lubrication of the machine.
GEAR BOXES – Before using your new machine,
check the oil in the main apron drive and beater drive
gear box. Keep the main apron gear box filled to the oil
level plug in cover of gear box. Beater drive gear box
should be filled to the center of the shafts. Use 80W-90
gear lube.
DRIVE CHAINS – Lubricate the drive chains with a
light machine oil. Keep chains aligned with sprockets.
This will lengthen the life of the sprockets and chain.
Lubricate chains often.
