This operators manual applies to the
Kongskilde combi cleaner type KDC 4000
Preface:
This users manual has been prepared in accord-
ance with EU-directive 2006/42/EC (Machinery
Directive).
Marking:
See enclosed Declaration of Conformity.
Description:
KDC 4000 is a combined screen- and aspiration
cleaner, designed for separation of grain and
impurities. The rotating screens are driven by an
electrical gear motor, and the cleaned crop can
be conveyed via the bottom outlet to a transport
system. The impurities are blown away together
with the aspirator air, and should be separated
through a cyclone and collected.
The cleaner can be equipped with screens
containing different hole sizes, depending on the
nature of the crop.
Capacity varies depending on the crop to be pro-
cessed, up to 40 tonnes per hour in easy oating
crop, depending on the requirements towards purity
of the crop.
The cleaner is primarily designed to be used for
pre cleaning of grain, corn, canola, sun ower
and beans from larger and smaller impurities.
Furthermore, the cleaner can be used for grading of
malting barley.
The cleaner should be feed continuously.
Typical application:
The combi cleaner has been designed for the pre-
cleaning of wheat, barley, rye, oats, rapeseed,
maize, peas, soybeans and sunower for larger and
minor impurities.
Warning notes:
• Take care that all guards are in correct position
and xed during operation.
• Always stop the combi cleaner prior to repair
and maintenance and avoid unintentional start of
the combi cleaner. Lock e.g. the on/off switch on
the built in control box or install a safety switch
mounted in the electrical installations to avoid
unintentional start of the cleaner.
• Only turn the screen drum manually when re-
placing the screens. Never turn the screen drum
by switching on the gear motor, when replacing
the screens.
• Use always gloves when replacing screens. The
screens may have sharp edges.
• Never put the hand in the outlet of the trough
auger.
• Never leave the outlet open, while the cleaner is
in operation. Connect the outlet to a container or
to a min. 800 mm long OK160 pipe, to prevent
access to the rotating parts. Never use quick
couplings, use only the provided bolt couplings.
• Never put your hand into the inlet or outlet open-
ing of the blower during operation.
• All electrical installations must be effected ac-
cording to the current legislation.
• In case of abnormal vibrations or noise, stop the
cleaner immediately and investigate. If in doubt,
call in expert assistance for repair and mainte-
nance.
• Mount the cleaner on a solid and plane base, to
avoid the cleaner tipping over.
• If the cleaner is to be moved, use the four lift-
ing points in the corners (marked with the chain
symbol) or use a forklift or the like grabbing in
the rails under the base frame of the cleaner
at the indicated points. The forks must be long
enough to lift in both sides of the cleaner.
Warning signs:
Avoid accidents by always following the safety
instructions given in the manual and on the warning
signs placed on the cleaner.
Safety signs without text are used on the machine.
The signs are explained below.
Read carefully the manual
before using the cleaner, and
observe the warning signs on
the cleaner.

Floor brackets:
If the cleaner is mounted on a platform or similar,
it is important that the cleaner is secured against
falling down. It is therefore advised to bolt it to the
oor, by means of the two supplied oor brackets.
The oor brackets are attached to the angled brace
at delivery of the cleaner. They can be removed for
attachment onto the transport wheels´ axle. Hereaf-
ter the oor bracket can be bolted onto the oor.
Height adjustment:
The height of the cleaner can be adjusted in both
ends by means of the telescopic legs. Lift the clean-
er above desired height, move bolts to a suitable
hole location, and lower the cleaner. Make sure the
cleaner rests on all four legs.
Take care that the guard for the V-belt transmission
is in correct position and xed during operation.
Never put the hand in the
outlet of the trough auger,
while the cleaner is in
operation.

Transport brackets:
KDC 4000 can be equipped with transport brackets
for the purpose of protection of the cleaner during
shipment.
When the cleaner is installed in the nal set up,
the transport brackets can be removed.

The cleaner is having small wheels in the back
end for transportation in the length direction. This
can be useful when loading the unit into or out of a
container.
Do not attempt to pull the cleaner acroos the oor,
this can bend the legs. In case a hoist is available,
the cleaner can be lifted by means of the 4 lifting
eyes located in the upper corners.

Principle of operation:
Unclean grain ows into the conical shaped inner
screen. The inner screen hole diameter allows the
grain to pass through, keeping the large impurities
back.
Having passed through the inner screen the grain
falls onto the outer cylindrically shaped screen.
Its slot dimensions are designed to keep the grain
back and allow light impurities to fall through. The
drum containing the inner and outer screens rotates
at approx. 22 rpm.
The combi cleaner is installed at an angle of inclina-
tion of approx. 9° to the rear, causing the crop to
move across the screens as a result of the rotary
movement of the drum.
After the mechanical cleaning, the crop is carried
to an aspiration cleaner where light impurities and
dust are extracted.
The impurities from both screens are collected in a
trough at the bottom of the unit.
At the bottom of the trough is an auger carrying the
trash to the front of the unit where the screenings
may either be discharged through a separate grav-
ity outlet (e.g. used when grading malting barley)
or delivered into the trash blow line by the combi
cleaner's fan and discharged together with the light
impurities.
Oversized impurities separated by inner screen can
also be discharged separately.
