General machine Safety and accident prevention
All aspects of safety advice, whether through this manual or by national accident
prevention regulations must be observed:
1. Warning signs and other notices on the machine are there to provide you with
visible important information for safe operation of the machine and to reduce the
risk of personal injury.
2. Before attempting to start work, please familiarise yourself with all equipment and
controls and the functions they perform.
3. Please ensure any users wear close-fitting clothing. Avoid using loose fitting
clothing.
4. Keep the machine clean at all times to see visible signs of wear.
5. Check around the machine before starting it up, to ensure there are no obstacles
in the way (including people)
6. Only start the machine up if all protective guards are fitted correctly and in their
protective positions.
7. Dangerous parts are located behind the protective covers. These do not
necessarily come to a standstill when the drive is switched OFF. Therefore, keep
well clear until such parts have come to a complete standstill.
8. Only carry out maintenance, repair and cleaning work on the machine when the
machine is electrically isolated.
9. NEVER allow persons to stand on the machine whilst working!
10. The designs and functions of intake and discharge mechanisms i.e. rotating
shafts, conveyors etc. means they cannot be fully protected. Therefore always
keep a safe distance from such moving parts when the machine is in operation.
This advice also applies to any ancillary equipment.
Only carry out work on the unit when the isolator is switched OFF

Functions and operations of the Separator
Exercise extreme caution when performing any
adjustments to the machine.
The unit consists of:
1. 4 or more Spiral Shafts (variable speed)
2. 4 or more Clod Roller shafts (variable speed)
3. Spring tension adjustment for the clod rollers
4. Clod roller height adjustment
5. Clod roller gap adjustment
1. Spiral Shaft
The spiral shafts consist of up to 14, 6 fluted spiral segments per shaft. The spiral shafts
are fi ed in position and cannot be moved.
In order to remove a spiral shaft (for replacement of spiral segments), there is a plate
bolted to the main side panel which when removed, allows the shaft to be drawn straight
out of the side.
Chain adjustment for the transfer roller drive is not necessary as this operation is
performed by the self-adjusting chain tensioner which should be set pre-tensioned.
2. Clod Rollers
The clod rollers are held in position by a hanger which is fi ed to the up/ down
adjustment profile using a circlip. The clod rollers are adjustable up and down as well as
left to right in order to increase/ decrease to gap between spiral and clod roller to
achieve more/ less separation.
There is a scraper positioned under each clod roller to keep the roller free from soil etc.
sticking to it. It is important that these scrapers are correctly adjusted with a minimum
gap of 3 mm.
Direction of rotation is an important factor. The unit is supplied with the option of running
the clod roller in either direction .If the direction of the clod roller is needed to be
changed for any reason we strongly recommend the scrapers are turned around at reset
to their 3mm gap for correct scraping of the roller. Warranty claims will not be upheld if
the scrapers are not correctly fitted for their use.
3. Spring tension adjustment for the clod rollers
Clod rollers should not “spring away” e cessively only to allow larger particles to pass
through such as stones 1” or greater. Spring tension is usually set at the factory but if
more tension is required or if springs are replaced etc the tension on each spring can be
adjusted by the M12 studs located below each clod roller. First loosen the locking nut
then adjust with a 19mm spanner to the required position, you may find that this will alter
age 4

the gap between the clod roller and the spiral roller which will affect the separating of the
machine. Therefore it is important to adjust all other spring tension adjusters to obtain
equal gaps throughout the machine.
4. Clod roller height Adjustment
5. Clod roller gap Adjustment
6. Do’s and dont’s
Never run the machine when the clod rollers are in contact with the spiral rollers (there
must always be a gap present) or severe damage may occur!
If the clod rollers are in the e traction mode e.g. running in the opposite direction to the
spiral rollers it is permitted to have the rollers touching. Care must be taken however in
dry conditions as both rollers surface speeds should be similar as one may act as a
brake against the other. In wet conditions the clod roller can be run at a much slower
speed if required in the e traction mode.
age 5
In order to adjust the Clod Roller height, there is a
turnbuckle adjuster or a linear ram located on the top
edge of the main panel. To adjust the height,
lengthen the turnbuckle to lower the clod rollers and
shorten it to lift the rollers. It is advisable to adjust
the turnbuckle in small amounts to avoid jamming of
the movement. As the turnbuckle adjust both sides
of the machine at once, both left and right settings
will remain equal.
Adjustment of the gap is achieved b firstl loosening
the 2 x M12 pinch bolts and then turning the starwheel
adjuster either forwards or backwards with a 19mm
socket. This adjusts all of the clod rollers together,
closer to or further awa from the spiral rollers. Ensure
the gap on both sides of the machine is adjusted
equall b using the guide under the pointer. The
spring tension is not effected during this adjusting and
therefore will not need re-adjusting. Remember to re-
tighten pinch bolts after adjusting. To fine tune the gap
there is an M12 bolt which moves the clod rollers
individuall and increases the spring tension (as
mentioned above).

Getting the best from your Evolution Separator
Do not attempt to adjust the settings of the machine until you have read and
understood the information contained in this booklet.
Summary
There is an infinite set of adjustments available on this machine and care should be
taken when adjusting parts of the machine. It is advisable only to alter 1 setting at once
so to avoid confusing what is happening with the machine.
Shaft speeds
This has the most pronounced effect in terms of separation. Generally speaking the
faster the spirals turn the less the machine will separate (ideally between 120 and 130
RPM). The aim is to run the spiral shafts at the minimum speed to achieve ma imum
separation without loss of the crop. To help achieve this it is possible to run the clod
rollers at different speeds: faster for ma imum e traction, and slower for less separation
(this can be as little as 30 RPM).
Clod roller Adjustment
The clod rollers become more aggressive at separating when they are in a higher
position and much less when lowered. When separating large particles such as clods of
earth, a higher position for the clod roller allows such debris to stall for a while which will
allow the flutes of the spiral rollers to grind down the clod.
The gap adjustment is also critical and once set to a minimum will eliminate the loss of a
small crop such as salad potatoes or baby carrots and dramatically improve self-
cleaning on sticky soils.
Clod roller direction
For root crops such as carrots parsnips, onions, shallots, bulbs etc we recommend that
clod rollers run in the same direction as the spiral rollers. On main crop potatoes
generally 2 or more of the clod rollers can be reversed, this will allow haulm to be
e tracted and larger clods depending on the level of debris.
In Summary (contra rotating)
Ma imum separation
• Reduce speed of spiral rollers
• Increase speed of clod rollers
• Lift clod rollers up
• Increase gap between spiral and clod roller (Can reduce self-cleaning in wet
• conditions)
Minimum Separation
• Increase speed of spiral rollers
• Decrease speed of clod rollers (or change direction to forward)
• Lower clod rollers
• Decrease gap between spiral and clod roller

Maintenance
General
Regular cleaning is a precondition for good operational reliability. The following advice
is to be observed before starting any servicing, maintenance or repair work on the
machine.
Observe the instructions for adjustments, inspection and maintenance activities provided
in this manual at all times.
Instruct operators before beginning maintenance work and appoint a person to
supervise such work.
To avoid the risk of accidents when replacing larger parts, ensure suitable lifting and
safety equipment is used. Never work or stand under suspended parts!
Always observe safety procedures when carrying out maintenance concerning
operation, adaptation, conversion, adjustment, inspection and servicing of the machine.
Before cleaning the machine with water or high-pressure cleaners or other cleaning
agents, cover any openings (for safety and operational reasons) must be protected
against ingress of water, steam or cleaning agents. Special care must be taken with
hydraulic motors and any electrical components.
After cleaning remove any areas covered by tape or other materials used for guarding
against water, steam or cleaning agent ingress.
Always retighten any screwed connections that have become loose during maintenance
and repairs.
Any safety devices removed for cleaning, maintenance or servicing purposes, must be
refitted and secure upon completion of the work carried out.
Ensure that all oils, consumables and replaced parts are disposed of safely and with
minimum environmental impact. If you are unsure where to dispose of any of these
materials, contact your local waste management office for advice.
Cleaning the machine
Only carry out cleaning work when the isolator is switched off!

Cleaning after every operation
In order to keep wear down to a minimum, please observe the following advice:
 Remove all deposits from the whole machine
 Inspect the machine for damage and replace defective parts immediately
 Clean the machine thoroughly inside and out as dirt attracts moisture and leads
to corrosion
 If using high-pressure cleaning equipment do not direct the jet of water at
bearings and always use a wide-jet nozzle moving from side to side.
 Do not use any cleaning additives.
 Spraying pressure ma imum 100 bar and water temperature no higher than
20°C.
Please follow the instructions below at regular intervals:
 Clean the machine thoroughly (see cleaning after every operation)
 Clean all drive chains thoroughly and seal with a good quality chain lubricant to
prevent corrosion
 Smear grease on the discs and threads of all spindles as well as any
adjusting/tensioning screws
 Check moving parts (hinges, etc) for ease of movement (dismantle if necessary)
clean and check for signs of wear. Replace with new parts as needed.
 Lubricate all hinges, pivots, etc.
 Grease bearings weekly
 Repair paint defects, protect any bare metal with a rust inhibitor
 Make a list of spare parts needed and order them in good time. Use only genuine
parts as listed in the parts list to ensure full compatibility and ma imum wearing
characteristics.
Switch off isolator prior to carrying out any maintenance work.
Screwed connections
Check all bolts for tightness, retighten if necessary.
Mechanical drives- Electrical motor / Gearbox
Clean the gearbox before carrying out any maintenance!
Regularly check the gearbo for leaks. The recommended oil change periods are:
 After first 50 hours of operation
 Thereafter every 500-800 hours of operation and/ or once annually.

Chain drives
Caution! Mount all guards correctly after completing any
adjustments.
Caution! RISK OF INJURY!
Mechanical drives
Carry out a visual check on all feed in/ transfer
roller drive chain on a regular basis for damage.
Replace if needed. Chain tension is normally
performed by the spring loaded chain tensioner
and do not normally need any attention, but some
stretching of the chain may occur over time and a
chain link may need e tracting to obtain required
tension.
Lubricate all chain drives periodically with a good quality non-fling chain lubricate to seal
the chain and prevent corrosion. It is recommended that during the first few hours of
operation the chains are checked for tension.
• Chains which are too loose cause rapid and e cessive wear on the roller links
and sprocket wheels.
• Chains which are too taut cause e cessive wear on the chain, the bearings and
the shafts.
Lubrication points/ grease nipples
Lubrication points are to be greased with multi-purpose grease. E cess grease
escaping from bearings is to be removed.
Bearing housings
All cast bearing housings (see e ample) have a grease
nipple located on them to grease the bearing inserts.
These housings are located:
• spiral shafts (both ends)
• clod rollers(both ends)
• clod roller hangers(both sides)
Lubricate all bearing housing greasers weekly
Remember to remove escaping grease from bearings.
