Operating advice for PCS dosing elements.

1. PCS dosing elements should be serviced annually. For performance optimization, test

your sowing material on a PCS test stand.

2. For seed treatment always use graphite. 1-2 table spoons is enough per big pack.

3. The ideal working speed is 6.0 bis 8.0 kmh. Excess speed leads to a decrease in dis-

tance precision, and imprecise depth control.

4. Occasionally check the brush bristles for wear .

5. Pay attention to the use of seed treatment materials and additives. They may cause

dosing difﬁ culties, premature wear and increased deposits on the dosing parts of the

machine.

6. Check all important elements of the machine for ﬁ ne tuning, including blower, air distrib-

utor ﬂ ap, PCS dosing elements, sowing hoses and tubes, PCS sensors, drilling depth

adjustment and the coulter system with double disc coulters, seed furrow former, catcher

rollers and pressure rollers.

7. Check brush lever and adjust if needed. The brush is so designed that setting position 3

equates to a standard brush. This position works well for medium-grain seed. The lever

can be engaged to ﬁ ne tune the dosing efﬁ ciency for larger or smaller seeds by turning it

to the left or to the right. See table or sticker for details about brush setting.

Brush position adjustment table:

Grain shape Grain size in mm Brush position

Round grain > 6.5 1

Flat grain (dent maize) > 4.5 1

Round grain 5.5-6.5 2

Flat grain (dent maize) 3.5-4.5 2

Round grain 4.5-5.5 3

16 | Operating Instructions - Extract PCS 8652.80.101.1_en_8_0

Start-up and operation

Grain shape Grain size in mm Brush position

Flat grain (dent maize) < 3.5 3

Round grain 3.5-4.5 4

Round grain < 3.5 5

• Compare the grain size and form with the

adjustment table or with the size informa-

tion on the PCS dosing elements.

• Shift the brush lever to the correct po-

sition. In the example, position 4 is set for

round grain of size 3.5 to 4.5 mm.

• Adjust brush lever to the left if under-dos-

ing occurs.

• Adjust brush lever to the right if over-dos-

ing occurs.

Working

Sowing

1. Implement safety precautions for working.

2. Switch on tramline switching if tramlines are to be generated.

3. Switch on the half machine width shut-off if sowing is to start with only half the machine

width.

1. Move tractor servo to working position (= ﬂ oating position).

2. The machine combination is lowered.

3. Lower track marker.

4. Lower forward running marker.

5. Turn on p.t.o. and increase the rpm quickly up to the nominal speed.

6. Switch on the seed blower and set at the speed shown.

7. Switch on the PCS single-seeding.

8. Start the dosing procedure and wait for the drive-off signal.

Drive off when the signal sounds.

9. Bring the tractor quickly up to the given speed.

10. Keep the driving speed within the green range if possible.

Care and maintenance

Annually

Clean and check PCS-dosing elements

Fitting, inner cleaning and control of the PCS-dosing elements.

NOTE

Defects to PCS-dosing elements are possible through moisture and corrosion.

• Because of the hygroscopic characteristics of seed dressings, we recommend that the

PCS-dosing elements be thoroughly cleaned before a longer sowing break and at sea-

son's end.

Fitting the PCS-dosing elements

PCS-dosing elements are precision devices. They should be checked annually and main-

tained carefully.

Pre-stressed ﬁ nger elements accept the single seed grains

and feed them along a backplate to the elevator belts

. The grain brush

can be adjusted to suit various grain siz-

es and shapes. A stopper element with a soft rubber insert

slows the seed grain down and prevents skipping.

Check PCS-dosing elements

11. Take the black plastic cover off and remove the residues from the dosing element. Wipe

pelleting residues and buildup from the ﬁ nger elements and the backplate with a moist

cloth.

12. Check ﬁ nger elements and springs for damage and wear. The primary wearing part on a

ﬁ nger element is the inner heel which rubs against the backplate. Change ﬁ nger set if the

ﬂ at area is larger than 1.5 mm.

13. Check backplate and replace it if the brush in the area of the grain conveyor shows signs

of wear on the left side.

14. Check brush and replace it annually or after 30-40 hectares per row. Use only an adjust-

able PCS-brush. Other brushes are too stiff and increase skipping.

15. Check the stopper element for trapped deposits and wear. The inner side of the stopper

is visible through the exit hole in the backplate.

18 | Operating Instructions - Extract PCS 8652.80.101.1_en_8_0

Care and maintenance

16. Check the belt housing on the underside of the dosing element for dents and rough edg-

es.

17. Check plastic cover for damage or tearing.

18. Test the dosage elements on a PCS- test stand for performance optimization and correct

brush setting .

Clean PCS-dosing elements

Clean the PCS-housing interior by blowing it out with dry compressed air. Cleaning is to take

place outdoors. The seed tank must be empty.

CAUTION

Seed dressing is toxic and may irritate eyes, respiratory tract and skin.

• Use a face guard for eye and airway protection.

• Wear gloves to protect hands.

CAUTION

Danger of crushing from a running elevator belt with inspection cover open.

• Do not reach into the PCS-housing.

1. Open the PCS-housing inspection cover

2. Open the discharge aperture.

3. Activate the emergency operation mode

and set a speed of 1 kmh.

4. Activate and switch on the PCS-drive, and

switch on the seed blower.

5. Blow out the PCS-housing with com-

pressed air while the elevator belt is

running.

6. Check the edge of the grain conveyor and the housing backplate for wear. Have

maintenance performed in a specialist workshop if there is severe wear.

7. The elevator belt must run in the middle and the belt nubs must all be equidistant to

the housing backplate in the area of the grain conveyor.

8. Check the elevator belt and the belt nubs visually for cracks. Have the elevator belt re-

placed if it runs unevenly, if it is torn or has become brittle.

9. Visually check that the elevator wheel retainer nubs are complete. Have the elevator

wheel replaced if belt nubs are missing or broken.

10. Spray the inside of the PCS-housing with a preserving agent. A special preserving spray

suited to this purpose is available upon request. No lubricants containing preserving

agents e.g. WD-40

8652.80.101.1_en_8_0 Operating Instructions - Extract PCS | 19

Care and maintenance

NOTE

Maintenance and replacement recommendations.

• We recommend having the PCS- dosing elements inspected in a specialist workshop at

the end of the season.

• The elevator belts should be replaced in a specialist workshop after a operating period

of three years, at the most.

• The brushes should be replaced in a specialist workshop after 30-40 hectares of sowing

per row.

Storing removed PCS-dosing elements

1. Before storing the PCS-dosing elements, remove all seed grains and blow out all resi-

dues and dirt from the dosing elements using dry compressed air .

2. Shift the elevator belt so that all retainers are inside the belt housing, and to protect it

from damage.

3. Store the PCS-dosing elements in such a way that no seed grains lie on the stopper

element.

4. Store in a dry, rodent-free container.
