FAULT FINDING
1. Grains are too crushed, i.e. have a doughy appearance:

Rollers are adjusted too close to each other.

Machine speed is too high.

Add the distance between the rollers and reduce the speed so that the grain slides
through the rollers and does not stick to the roller surface. The recommended PTO
operation speed is 350 - 540 rpm.
The machine is now ready for Start Up Procedure
2. A mixture of whole uncrushed grains and doughy grains:

Rollers are not parallel to each other.

Adjust the rollers so that the distance is the same at both ends.

Check tension of leaf springs/hydraulic rams
The machine is now ready for Starting Up
3. Rollers have a doughy appearance and some grains are scattered around:

Scraper knives under the rollers are incorrectly adjusted or spring not fitted.

Clean scraper knives and check they peel the grains off the surface of the rollers
evenly. If necessary, adjust the position of the knives. The loadspring should press
each knife against the roller.
The machine is now ready for Starting Up
4. The Discharge Auger clogs up:

Elevator belts are broken or belt tension is loose.

Tighten the elevator chain and tighten or replace drive belts.

If the grain is too coarse, wind the crank anti-clockwise (taking care that the rollers
do not touch) to get the rollers closer to each other; or if the grain is too fine, wind
the crank clockwise to get rollers further apart.

Check that the flow of feed is not too high.

Check cross auger is clean from previous use.

Check PTO speed is between 350 - 540 rpm.
