EU-COMPLAINCE DECLARATION

DALBO A/S

DK-7183 Randbøl

declares herewith that the above machine ismanufactured in accordance with theprovisions of directive 2006/42/EC, which

replaced directive 98/373/EC and change directives 91/368/ECC, 93/44/ECC and 93/68/ECC on harmonisation of member state

legislation concerning health and safety requirements related totheconstruction and manufacture of machines.

hine corresponds to the safety requirements in the European Safety Guidelines.

Date:

Carsten Jensen, CEO

Application:

The Compact is used before andaftersowing to break up clods and press down

stones;it also improvesgermination. The Compact can beequipped

with a hydraulically controlled levelling bar, asan optional extra. It makes the

machine very effective on rough-ploughed land.

It is also used with advantage after stubble cultivation, to expedite the rotting of

straw and stubble remains andalso the germination of waste- and weed- seeds.For

rolling very loose soil,it must befitted with at least 50 cmrings.

The Compact is also used for rolling grasslands in the spring.This should bedoneas

soon asthe land can be driven over. Rolling eliminates stones andlumps of earth

from the surface,so that they donot cause obstruction later when the grass is

mowed.At the sametime, the Compact breaks up the surface of the soil, allowing

air to reachthe roots.

Noise:

Dust: V

Handling:

The Compact must not be used asa transport vehicle, pile driver, hydraulic press or

the like. Ifyou are in anydoubt, ask your dealer or DALBO.

The Compact must not be used to roll areas of road or similar hard surfaces.

When using the roller the operator must sit in the driver's seat on the tractor, and

there must beno other people eitheronorin the immediate vicinity of the roller.

Theroller may make somenoise when rolling with wom Cambridge rings, but this will

be far below the <langerlimit for tractor drivers.

A lot of dust can be raised during rolling under very dry conditions.

It is recommended that either the tractor doors and windows be closed or a dust

mask wom.

For transport purposes, the roller is supplied in the following separate parts:

The parts will be handled with a crane. Hook onto the side sections in the middle of

the squarepipe.

It must be fitted so that it tightens around the pipe during lifting.

V On the central section and drawbar yellow sitckers showing a lifting hook

indicate where to hook ontofor effective lifting.

Fitting:

Should be carried out in a workshop.See

Fig.7 and8.

A level floor, an approved crane cabable of lifting a minimum of 1000 kg and a

hydraulic pump with a single-acting and a double-acting take-off is required. It must

be able to exert a pressureof atleast 170 bar.

Install the central section vertically on the roller rings and wheel hubs. Fit the

drawbar with the pin in position 15,remember the split pin.

Fit the tilting ram, position 59.

Fit and adjust the support so that the height of the drawbar isapprox. 40 cm.

Connect the tilting ram to a single-acting hydraulic take-off; the hose ismarked

white.

Lift one of the wheel hubs with the cranewhilst carefully allowing the oil to drain out

ofthe ram

This will cause the central section to assume a horizontal position.

Lift each side section into position with the crane hooking onto it as described under

"handling". Secure the side sections with the pins, pos. 35, which are in tum secured

with the screws,pos.36.

Connect the hoses to the folding ram to a double-acting take-off.

Push the folding ram out almost to their full extent and fit, making sure that the

hoses donot cross.

Fit the wheels.

Apply pressure in order to push the folding ram all the way out.

Carefully rock the roller upwards by applyingpressure on the single-acting ram,

making sure that all the hoses are able to move freely.

Carefully retract the roller with the double-acting valve, keeping aneye on the hoses.

Ease the pressure on the single-acting ram sothat the side sections drop down into

their transport bearing.

Secure the hoses to the folding ram with the hose clipsand self-tapping

screws.

Fold the roller in and out a couple oftimes. Keepaneye on the hoses. Thefolding

ramsare throttled opprevent toofast a movement.This isnot of crusial

importance but it may giverise toa whistling soundin the pressure valve on the

hydraulic pump.

Tighten all screws securely, including hub nuts.

Theroller sections areswivelled back to the transport position in the reverse order

toextension.

Start-up:

Operation:

Maintenance:

No adjustments or similar action is necessary before starting to use the

Compact. The roller is drawn by the pickup-hitch of the tractor; which should

be about 40 cmabove the ground.

Remember to secure the draw bolt with a split pin or similar device.

Connect the hydraulic hose (marked white) to a single-acting valve. Connect the

othertwo hoses (marked red) to a double-acting valve.

All the hoses arefitted with 1/2"connectors. If the tractor is not equipped for these,

your dealer can help. A maximumpump pressure of 160bar isrequired.

Defective hoses must be repaired or replaced immediately.A broken hose can in bad

casescause personal injury or mechanical damage to the roller.

All operation must take place fromthe driver's seat andthere must be no-oneelse

in the vicinity of the machine.The changefrom transport to operational mode, and

vice versa, must be made while stationary on more or less levelground,with the

tractor almost idling. Tounfold, operate first the single- acting valve,sothat the

sidesections arelifted clear oftheir transport bearings;usethe double-acting

valvetounfold the side sections completely. Then lower the pressure from the

single-actingvalve, sothat the roller tilts down to the ground. It isadvantageous to

to allow the valves to float freelyduring rolling, if possible.

Toraise the roller, apply the pressure first with the double-acting valve, sothat the

long cylinder acrossthe roller is completely compressed. Then lift the roller

completely vertical with the single-acting valve. Fold the side sections in by means

of the double-acting valve. Lastly,lower them intotheir transport bearings using the

single-acting valve.

Theroller must be raised only for transport. It is not necessary to raise it when

tuming. It can also run backwards in the operating.position.

Recommended speed of travel: 4-5 mph.Moveslowly over stony ground. Tighten all

the screws, and alsobuh nuts, after the first working day.

Chassis - 3 lubrication points - lubricate daily.

Roller bearings - 6 units - lubricate every 50operatinghours. Lubricate the

wheel bearings onceper season.

Adjust the wheel bearings once a year,followingthe instructions for replace-ment

of bearings, points 1,2,11,12and 13.

After the first season the surface of the rings will have wom smooth and they will

therefore take up slightly less space. Adjust the resulting clearance down to max.

5 mm by moving the stop rings (see fig. 1). Remember to tighten the stop ring

screws well. It is advisable to slacken and retighten the screws a couple oftimes

so that they grip better.

Fig. 1:

Check the air pressure in the tyres before the season. It should be 5.2 bar.

For prolonged indoor parking in the transport position, the piston rod should be

lubricated with oil or grease.

REPAIRS:

Wheels: For changing wheels owing to punctures, etc., set the machine in the operating

position. This enables the wheel to be removed without using ajack.

Bearings, rings

and shafts:

Dismounting roller shaft with rings for replacement of bearings, rings or shaft.

This should be done in the workshop.

Side section - DISMOUNTING:

For this, an approved crane capable of lifting at least 1000 kg is required.

The roller should be positioned with the appropriate section beneath the crane

- preferably coupled to a tractor, otherwise, a hydraulic pump with a single- acting

and a double-acting valve is needed. It must be able to deliver a pressure of at least

170 bar. Connect the opposite section to the guide over the transport bearing so

that it can still be moved upand down. Using the single- acting valve, lift the side

sections clear of the transport bearing. Use the double-acting valve to swing the

side section concemed about 1 m out from the side.

Start carefully with two chains/slings around the rings about 1 m apart. Lift until the

chains/slings are taut. Thoroughly loosen the bearing nuts. Lift with the crane until

the screws are loose. Remove them and the whole shaft can be manoeuvred out.

Clear all grease from the bearing housings. Remove any burrs on the protruding

shaft end with a file. Loosen the pointed screws in the bearings; the bearings

can then be pulled out.

When the stop ring with the two pointed screws has been removed, the roller

rings can be pulled off the shaft.

MOUNTING:

Cambridge rings. Start with a smooth ring with the "nose" pointing inwards (see fig.

3). This is followed by a serrated ring with the smooth side facing outwards. This

must be pushed right over the boss ("nose") of the smooth ring. Fill the shaft up in

this way until a space of about 12cm remains. Omit the last serrated ring. Ensure

that the rings arepacked tight together.

Fig. 3:

roller middle

Crosskill rings. Note the direction of rotation of the shaft.

Start with a small ring, which must face the direction shown in fig. 4.

Then fit a bush, and a large ring above this, facing the direction shown in fig.

4. Finish with a small ring. Ensure that the rings fit tightly together. Fig.

roller middle

Welled rings. Start with two rings, screwed together as shown in fig. 5.Fill the

shaft until a gapof about 22cm is lefl. Close off the shaft with two rings bolted

together. Ensure that the rings arepacked tightlytogether.

Fig.5:

roller middle

Insert the stop ring, fig. 3-5, pos.2, and tighten well. It is recommended

that the screws be tightened and loosened a few times to ensure that they grip

betler.

Then insert the bearings on the shaft.

V Unfold the roller frame asdescribed above.Attach two slings/chains to the

frame. Lift the complete shaft with rings, using anapproved crane (min.lifting

capacity 800 kg)and lower it into the roller frame.The end with the last mounted

stopring (fig. 3-5,pos. 2) must point inwards on the roller.

Fit the bearings and tighten. Remember to turn the lubrication nipples to

allow for lubrication (fig. 6). Use Locktite no. 270 on the pointed screws and

tighten well. Close up the roller as described under "Operation".

Fig. 6:

Center section - DISMANTLING:

If possible, attach the roller to a tractor; if not, a hydraulic pump with a single-

acting and a double-acting valve will be required. The pump must be able to deliver

a pressure of at least 170 bar.

Use the single-acting valve to lift the side sections clear of the transport

bearings and use the double-acting valve to swing them right out.

V If the roller is not attached toa tractor, it must be opened up gently toensure

that it does not tip overbackwards.

Use the single-acting valve to lower the roller until the roller rings are resting on the

ground.

V Thedouble-acting valve MUST NOT BE OPERATED in this situation.

V Secure the roller mechanically in this position, asa safeguard against the

possibility of hose rupture.

V Thebolts holding the ball bearings can now beremoved. Take care not toinjure

your fingers.

Next, using the single-acting valve carefully tilt the roller upwards, ensure that

the roller shaft stays down on the ground.

ASSEMBLY:

Cambridge rings. Fit a stop ring about 12cm in along the shaft (see fig. 3). Then start

with a smooth ring with the "nose" pointing outwards (see fig. 3),and follow with a

serrated ring with the smooth side facing inwards. This must be pushed right in on

the boss ("nose") of the smooth ring. Fill the shaft up in this way until a space of

about 12cm is lefl.Omit the last serrated ring and finish with a stop ring.

Crosskill rings. Fit a stopring about 12 cm in along the shaft (see fig. 4). Start with

a small ring, then fit a bush, and a large ring above this, the spokes of which run

the same way as on the first ...... And so on,finishing with a small ring and a stop

ring.

Welled rings. Fit a stop ring about 12cminto the shaft. Start with two rings, screwed

together asshown in fig. 5.Fill the shaft until a space of about 22 cmislefl.Close

off the shaft with two rings bolted together and a stop ring.

Loosen the stop ring screws. The projecting shaft ends must be of equal length. This

is achieved by striking the shaft. Make sure that the rings are very tightly packed.

Tighten the stop rings well. It is recommended that the screws be tightened and

loosened a few times toensure that they gripwell.

Then push the bearings in along the shaft ends.

Open up the roller frame as described above under 'Dismantling'. Push the whole

shaft into the frame. If it isa crosskill roller, ensure that the direction of rotation is

the sameasshown in fig. 4. Mount the bearings and tighten securely.Remember to

tum the grease nipples soasto allow for

lubrication (fig. 6).

Rams:

Raise the roller to the vertical position, using the single-acting valve. The

DOUBLE-ACTING VALVE MUST NOT OPERATED until the

single-acting valve is fully extended.

Folding ram:

This can be done with the roller in either the transport or the operating position,

where the ram is in both instances pressureless; but the operating position is

recommended.

Remove the hoses. It isrecommended that a bucket beplaced undemeath to

catch anyoil. Remove split pins and washers. The ram, weighing 21 kg, can be

dismountedalso.
