Function Problems

If the cylinder winds up and gets clogged, check for:

•  crop too damp or green

•  forward speed too high

•  cylinder-concave clearance too wide

•  cylinder speed too low

•  cylinder bars damaged or worn

•  rear beater damaged

If the grain conveyor is clogging, check for:

•  chauffer sieve set too far open

•  insufficient fan speed

Cleaning Instructions When Going From One Crop To Another

Although the combine has been built to “self-cleaning” it is necessary to clean it carefully

when going to one crop to another. Some grains may be left anyhow. This may happen 

especially when harvesting in wet condition.

Drive the combine to suitable open place. Move gear lever to neutral and engage the parking

brake. Stop the engine and remove the ignition key so that no unauthorised person can start it.

Do not carry out any cleaning operation while engine running

Cleaning with compressed air is recommended, also appropriate brush can be used.

•  Open all cleaning doors.

•  Remove sieve and clean it.

•  Clean the supporting grooves of the sieves in the shaker shoe.

•  Clean the straw walker bottoms

•  Run the combine threshing machinery for 2 to 3 minutes with the cleaning fan at maximum 

speed and pushing the direction lever to and fro. Lift and lower the cutting table against the 

ground without starting it.

•  Stop the threshing machinery.

•  Check that the grain pan is empty; if necessary clean it.

•  Check the spaces below the grain conveyor and remove any grain remaining.

•  Shake the chain of the feed conveyor and clean the housing inside and out.

•  Clean up the cutting table.

•  Remove the bottom auger of the grain tank and brush up the bottom furrows.

•  Clean the unloading pipe by agitating and turning the auger by hand to the left while the 

pipe is unlocked and the grain is running down off the lower pipe end.

•  Fit the parts removed properly and close the doors.

¹ (if return system fitted)

*) With open bottom of fan housing

**) Use wide space, heavy wire concave

***) Use 3…4 deawning plates in front of concave

The normal concave front to rear clearance ratio is 2 to 1. In dry conditions when the straw

is extremely brittle, it is better to use a concave ratio of 1.5 to 1...1 to 1, see fig. 31. In other

words, the clearance at the rear of the concave is bigger than in the normal setting. This will

reduce straw damage and therefore walker losses.

The basic setting is changed by extending the rear supports of the concave as instructed

in chapter “Maintenance“ fig. 66. The ratio shall be checked every time the clearance is

adjusted using the wheel in the cab. The mechanism always changes the clearance in the ratio

of 2 to 1.

Return to the basic setting as soon as the conditions get back to normal.

Service and maintenance

SAFETY

Safety regulations and instructions

Installations and adjustments can only be made by a person with the required skills and qualifi-

cations and the necessary knowledge of the machine in question.

 

Installations, adjustments and repairs must be undertaken with the engine stopped and the igni-

tion key off. 

All the moving parts must be in balance and stopped and, when necessary, locked. Support the 

cutting table and the reel in their top positions. Ensure that there is no pressurized energy in the 

fluid systems before opening mechanical or hydraulic couplings. (The gas accumulator for the 

table, the air conditioning equipment, the radiator, etc.)

Double-check that there is no risk of injury when starting the engine either during or after service 

measures. 

 

Ensure that all periodic checks and cleaning are carried out on time in compliance with the in-

structions so that no such malfunctions may occur which can cause any risk or hazard. 

When installing, adjusting, servicing or repairing a technical device,

•  without unhampered visibility to all its parts, or

•  on which several people are working, or

•  which is started from a control centre, or

•  which is started from such a place that the whole device can not be seen, it must be 

ascertained that the device may not be started unintentionally or defectively.

This can be guaranteed by locking the starting device in the stop position.

When installing, adjusting, servicing or repairing a technical device with energy reserves, no

measures are allowed to be taken before it has been ascertained that no hazardous machine

movements may occur.

When starting a technical device, the operator must ascertain that nobody will be injured.

The service and periodic checks of a technical device must be carried out in accordance with

the Manufacturer’s instructions and operating conditions so that no such malfunctions may

occur which can cause any risk or hazard.

General Instructions

•  Make sure you are skilled enough to service the combine before undertaking any 

maintenance work. If not sure, contact a qualified service man.

•  Get acquainted with the combine structure and the following service instructions before 

undertaking any work.

•  Wear appropriate protective clothing.

•  Use appropriate tools and other equipment.

•  Handle the combine and any work materials in such a manner that there’s no risk of injuring 

yourself or anybody else, or damaging the environment.

The Functioning of the

Combine Is Based on the

Condition of the Knife

Check that each knife holder touches the

knife section lightly. Adjust by bending the

holder down, fig. 52.

Check the reversing points of the knife, fig.

53. The knife sections should centre in the

knife fingers at the inner and outer extremity

of its stroke.

If adjustments are made, make sure that

the knife joint is turned into the right depth

at the end of the knife, fig. 55.

The final adjustment is made by removing

both clasp nuts B of knife drive shaft A,

fig. 54, and turning the shaft in the required

direction. When turning clockwise, the

reversing point is shifted to the left, when

turning counter-clockwise, it is shifted to

the right. One turn of the shaft shifts the

reversing point by some 7.5 mm.

Removing the Knife

When removing the knife count the number

of turns required to unscrew the ball joint.

Remove fixing screws A, fig. 55, on the 

connecting lever and remove the knife.

When changing the knife, loosen lock nut B

on the ball joint and count the number of 

turns required to unscrew the ball joint from 

the knife.

Screw the ball joint into the end of the

new knife using the same number of turns 

and check if the reversing point of the knife 

needs adjusting.
