Safety instructions
2. Do not move the mill during use,
when the hopper is full or when the
hopper is being filled. Make sure
that the hopper is empty before
driving.
3. It is recommended to wear type-
approved safety glasses during
crimping.
4. Keep your hands, clothes, tools
etc. out of the hopper.
5. Do not stand on the PTO shaft
or between the tractor and the

INSTRUCTIONS FOR USE
Recommendations
1. Routine checks before use
Perform these checks every time the device is used after it has been unused for a
while and before any other maintenance is performed.
2. Adjusting rollers
Roller adjustments are always checked before starting the machine and after any
maintenance work. Check roller adjustment at least once daily when the machine
is being used.
3. Start-up, starting crimping and use
Always performed after the routine checks have been carried out.
4. Ending crimping
Carry out every time the device is stopped and crimping has ended.

15
Routine checks before use
1. Check that all screws and bolts are tight enough. Replace any worn or rusty parts.
2. Place the elevator in an upright position and check elevator chain tightness at the
tensioner. Movement in line with the tensioner’s axis is allowed. Adjust the gear at the
top of the elevator if necessary.
3. In the bagger model, check the condition and tension of the auger chain as well as the
amount of lubricant in the lubricator.
4. Check the tension of the v-belts. When pressing with a finger, the belt must yield 1cm.
5. Make sure there are no foreign objects in the hopper.
6. Check the feeder (feeder shaft). Remove any straws or strings from the shaft. Clean the
platforms and level if necessary. Clean the guard magnets.
7. Check the condition of the acidifier system.
8. Monitor the condition of the hydraulics components. Repair any possible leaks.
9. Lubricate indicated points (grease nipples) with petroleum jelly.
NOTE! Make sure that all guards are correctly placed and installed before start-up!

Basic roller adjustments
The rollers must always be adjusted at the beginning and during the harvest season. If the
machine is in constant use, check the adjustments daily.
Checking the rollers
1. Adjust the roller clearance to the minimum using the adjustment crank (to open, turn
counter-clockwise).
Picture. Quick adjustment using the crank.
2. Adjust the roller tension spring to maximum. Use the hand pump to apply maximum
pressure to the cylinder (max.140 bar).
Picture. Hydraulic pump, ball valves and pressure gauge

17
3. Measure the roller clearance at both ends using a feeler gauge.
The minimum clearance is 0.3mm
The roller clearance must be same at both ends, i.e. the rollers must be perfectly
aligned.
Picture. Measuring the roller clearance
4. If the clearance is suitable and rollers are aligned, there is no need for further adjustments.

18
Roller adjustment
Roller adjustment is always carried out for both roller pairs, one side at a time. The mill is
delivered with default adjustments.
NOTE! If the rollers touch each other when turning, they may wear out very fast. The
warranty will not cover wear that results from incorrect use of rollers.
Picture. Roller adjustment
List of components:
1) Roller clearance adjustment crank
2) Hydraulics cylinder
3) Roller clearance coarse adjustment
4) Feeder hatch handle
5) Coarse adjustment locking nut
1. Release the coarse adjustment locking nuts (5) and release the roller clearance adjustment
screws (3).
2. Use the hydraulic pump to apply approximately half the maximum tension to the springs.
When the tension is fully released, the transmission gears are not necessarily fully
in line. First, pump the pressure up carefully and ensure that the gearwheels
connect correctly

3. Wind the roller clearance adjustment crank (1) so that the adjustment shaft arm is at the
furthest position.
4. Finger tighten the adjustment screws (3)
5. Tighten the adjustment screws (3) half a turn using a wrench
6. Adjust the roller clearance to 0.3mm at both ends using a feeler gauge
7. Tighten the locking nuts (5)
The mill is now appropriately adjusted and you can start crimping.
NOTE! Make sure that all guards are correctly placed and installed before start-up!
Adjusting rollers during crimping
The rollers can be adjusted during crimping using the adjustment crank. You can adjust the
coarseness of the grain by turning the crank. If the grain is too coarse or is not being ground
properly, the rollers can be moved closer to each other by turning the crank counter-clockwise. If
the grain is too fine, the roller clearance can be increased by turning the crank clockwise.
Monitor the quality of the grain regularly during crimping because the result may differ between
batches. Factors influencing the crimping result include the variety of grain, grain size,
temperature etc. In addition, monitor the moisture of grain because this will affect the correct
roller adjustments and the amount of preservatives needed.

Start-up, starting crimping and use
1. Make sure you have carried out the routine checks before starting.
2. Make sure that the crimper is adjusted appropriately.
3. Make sure that the crimper is placed evenly on the ground. If the mill is askew during
crimping, the grain may roll to one side of the machine.
4. (Ensure that the flow gauge is calibrated for the used preservative.)
5. Make sure that all guards are correctly placed and installed.
6. Close the feeder hatches.
7. Fill up the hopper with grain.
8. Apply maximum tension to the roller springs: (700HD ca. 120bar. and 1000HD ca.
140bar.)
9. Engage tractor PTO at 540rpm.
10. Open the feeder hatch so that the grain starts pouring down onto the rollers in a steady
stream.
11. Make sure that the rollers have enough time to pull all grain through. As flow increases,
tractor revs may require adjustment.
12. Make sure that the grain is flowing steadily onto the rollers and that all grain passes
through the rollers instead of accumulating on them.
13. Check the crimping result to make sure that every grain is ground. If you spot any
unground grain, move the rollers closer to each other. If dough balls are produced,
increase roller clearance. If there are both unground and doughy grains among the
crimped grain, the rollers are touching at one end and the clearance is too big at the other
end. Adjust the mill according to the above instructions.
a. The sampling point is located between the machine and the bagger. In the
elevator model the sampling is done from the pile of ground grain.
14. Start the acid pump and adjust the flow gauge according to how much grain passes
through the rollers.
15. Crimping coarseness can also be adjusted by changing the rotation rate of the rollers.
16. Monitor the cleanliness of the rollers and the functioning of the scraper knives during
operation.
17. Add water during crimping if necessary.
18. Ensure maintenance as instructed in this manual.
NOTE! Make sure that all guards are correctly placed and installed before start-up!
