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

Warning Symbols and Advice

The warning symbols are to indicate dangerous areas of the machine and specific

operations for safety and trouble-free operation.

Please follow all warning symbols and information stickers at all times!

Always ensure warning symbols and information stickers are kept clean and in legible

condition. Any stickers that are not legible must be replaced immediately and attached

in their designated positions on the machine!

All guards must be securely closed when machine is

running

Do not remove or render illegible any warning stickers.

Replace any immediately if this happens!

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).

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!
