[1] When fitting a wheel & tire to a hub, do the wheel nuts up in rotation to the correct tension. To achieve this choose a wheel nut & tighten, then go clockwise to the next wheel nut & tighten & so on until all wheel nuts are tight. Then repeat the procedure to check that all nuts are tight. Do not use impact tools to tighten wheel nuts. For a guide to the correct tension of the wheel nuts please use the appropriate tension for your size wheel nuts from the Bolt Torque Settings table.

Torque values are for dry threads and surfaces however it is permissible to apply a small amount of anti corrosive oil to the threads.

Section 1Unpacking

Unpacking We recommend the use of suitable lifting equipment

for unloading and assembly

• Before unloading any loads please inspect exterior

for damage

CAUTIONTake care when opening doors as load may have shifted or restraints may have broken.

• Remove boxes from doorway of container one at a time using a forklift truck. Each box weighs approximately 2600 lbs (1200kg)

• Check strapping on each bundle before attempting to remove

• Attach chains to the packing frame using shackles and using suitable equipment (eg. fork-lift or tractor) drag framework bundles out of container. To move bundles away from front of container lift from side with forklift. Do not lift under angle iron frame, lift only under centre frame. Each bundle weighs approximately 7000 lb (3200 kg).

Connect chains to these points

We recommend the use of suitable lifting equipment

for unloading and assembly

CAUTIONBefore cutting straps attach slings or chains and take the weight of the frames to avoid them slipping or falling and causing injury.

CAUTIONWear eye and hand protection when cutting straps. Sharp edges are exposed as straps separate and may cause injury.

CAUTIONTo avoid falling or moving components, before cutting straps attach slings or chains to individual pieces and only cut the straps holding the piece to be lifted.

• Remove boxes from rear of container one at a time using a forklift truck. Each box weighs approximately 2600 lbs (1200 kg)

• Cut straps holding bundles and separate parts and place in assembly area

• Once all parts have been identified machines are ready for assembly

• Identify parts for each machine by serial no. or description and separate. Open parts box and check that all parts are accounted for against checklist

• Read assembly instructions before proceeding.

Lift under centre frame only

Do not lift under packing frame

Mounting Swivels Page 1 of 1

Fixed housing end of swivel should always face forward

Rotating seal end of swivel should always face rearward

Mounting like this prevents dirt getting forced into the seals of the swivel increasing longevity of the swivel

Swivels attached to the leading ends of the chains should have the rotating seal end attached to the chain like shown

Swivels attached to the trailing ends of the chains should have the fixed housing end attached to the chain like shown

For Example

Fixed housing end of swivel should always face forward

Rotating seal end of swivel should always face rearward

For example

Swivels attached to the leading ends of the chains should have the rotating seal end attached to the chain, as shown

Swivels attached to the trailing ends of the chains should have the fixed housing end attached to the chain, as shown

Mounting like this prevents dirt getting forced into the seals of the swivel increasing longevity of the swivel

` Fitting cast link retaining pins

Please install cast link retaining Pins (3/8” x 3” Roll Pin, part number 0262-3-8X3) on all cast disc links. Failure to do this could lead to the discs becoming dislodged during transport causing severe damage or injury.

Hydraulics

Before folding the machine for the first time, ensure all hydraulic cylinders are charged with oil.

To do this, run the hydraulics through the unfold sequence until the outer wings are straight and the centre cylinders are centred in the slots. (It may take a few minutes for the cylinders to charge completely).

Failure to do this could result in severe personal injury and/or damage to the machine.

Basic operation and chain tension

Model inches mm

30 12.9 330

When less than 4” (100mm) of thread remains visible on the adjustor bolt then a link must be removed from the chain

Basic OperationUnfolding:1. Walk around and inspect the machine. a. Check that chains are not hooked on framework b. Check swivel bolts are in place and not broken c. Check th at height adjusting chains have not fallen out of their slotted plates during transport. d.Ensure front lift cylinder depth stops are fully engaged on cylinder shaft.2. Lower front A frame to working height.3. Unfold wings holding the hydraulic lever until both the main center cylinder pins have centered in their slots. (If chain pulls tight during unfold, stop and inspect if chain is hooked) 4. Lower rear tail by holding hydraulic lever until tail and modules are completely lowered to working position.5. Walk around and check that all chain links are straight and that working height of all swivels is correct for field conditions. Adjust if neccessary.6. Move off with all chains in working position. If neccessary it is acceptabe to raise front A pull to transport height. This will lift the front chains off the ground and reduce the load on the tractor. Lower the front A pull once moving satisfactorily.

Folding:1. Lower the front A frame to working height. (This is important to ensure that all chains locate correctly in their transport rests).2. Raise the Rear Tail and modules by holding the hydraulic lever until they come to a complete stop.3. Fold the wings. They should move as follows; main center cylinders will retract, one or both, until the wings stand vertically. The left outer wing then the right outer wing will fold down.4. Raise front A frame to transport height.5. Walk around and check that chains have located correctly in transport rests. (30’ only, close wing transport lock valves).

Setting for correct chain tensionWingsUse the spanner supplied. Loosen the lock nut adjacent to the tensioner assembly body.Turn the tension bolt clockwise to compress the coil spring. Correct tension is acheived when spring retains its set length when operator rolls the chain fore and aft on the ground. Retighten the lock nut.

See table below

Spring Compression Length

Module and chain tension

ModulesLoosen the lock nut on the draw bolt.Tighten the adjusting nut clockwise until the outer face of the spring retaining washer is flush with the body of the module tensioning unit.Retighten the lock nut.If more than 8” (200mm) of thread is exposed then a link should be removed to maintain correct adjustment.

Importance of chain tensionOperationalIt is imperative that the correct adjustment be maintained. Only through correct adjustment can a smooth and level finish be achieved in field working. Loose chains lead to :• Uneven performance across the width of the machine • Uneven weed control• Unsatisfactory incorporation• Ineffective levelling• Accelerated or premature chain wear• Chains failing to engage with transport locators when folded• Machine damage when folding or unfolding• Uneven field surface with ridges and furrows being created. The leading 1/3rd of a loose chain is much more aggressive than the trailing 1/3rd and the center. This will mean that middle of the machine’s front pair of chains will aggressively move soil outwards. The machine’s rear pair of chains, if loose, have their aggressive 1/3rd near the wing extremity. It follows then that as the front discs push soil outwards, the least aggressive portion of the rear chain follows them and does not balance the soil movement. This is exacerbated at the wings, effectively creating a broad ridge about halfway out each wing. It won’t be evident in one pass, but is possible if care is not taken over time. A correctly adjusted machine will not cause this phenomenon.

Correct working height

Settings for correct working height

To adjust the swivel height at the wings, relocate one of the polyurethane spacers either above or below the fixed mounting tube.

Adjustment

1 Loosen chain tension completely

2 Undo self tapping screw from corresponding spacer then prise open the spacer and spring it off of the drop leg tube

3 Replace it in the selected position after raising or lowering the drop leg

4 Reinstall the self tapping screw and re-tension the chain

It is possible to install all spacers either above or below the mounting tube giving a maximum of 4” (100mm) of adjustment.
