MACHINE OPERATION

SECTION 2 MACHINE OPERATION
Before operation
• Carefully study and understand this manual.
• Do not wear loose fitting clothing that may catch in moving parts.
• Always wear protective clothing and footwear.
• Be sure that there are no tools lying in or on the equipment.
• Do not use the machine until you are sure that the area is clear, particularly of children or animals.
• If this machine is being used in a dry area, or in the presence of combustibles, care should be taken
to prevent fires and firefighting equipment should be readily available.
• Familiarise yourself and other operators with the machine’s operation before using.
Pre-operation Checklist
Check Item:
Done
1. All wheel nuts, bolts and nuts are tightened to the correct torque setting
2. Split pins are in place
3. Stickers and warning signs are in place
4. Hydraulic fittings are tight and have no leaks
5. Chains are adjusted so that all springs are compressed to 330mm/ 1’ 1”
6. Check swivel bearings are not seized and still turning freely

CHAIN OPERATION
SECTION 3

13
SECTION 3 CHAIN OPERATION & CORRECT SETUP
Importance of Chain Tension
Operational
It 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
• 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 centre.
This will mean that the 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 will not be evident in one
pass but is possible if care is not taken over time.
A correctly adjusted machine will not have this problem.
Chain Tension
1. Loosen the lock nut on the draw bolt.
2. Tighten the adjusting nut clockwise until the outer face of the spring retaining washer is pushed
with the body of the module tensioning unit.
3. When 7-7/8" / 200mm or more of tensioner thread is visible then one link must be removed from
the chain set to maintain correct tension adjustment. Spring length of 330mm / 1’ 1”
4. Retighten the lock nut.

15
Chain Curve
Correct chain tension will ensure that the entire length of discs will roll as one. This minimises the
movement between each link. If a chain is not adjusted and runs loose, each link acts as a
universal joint as the curved chain rolls along. The wear rate between each link is greatly
accelerated and can lead to premature failure. The chain should not wear out before the discs are worn
down.
ONLY POOR ADJUSTMENT CAUSES PREMATURE WEAR
Indicator line shows acceptable curvature when operating.

16
Chain Mount Arm Height Adjustment
1. Use tractor hydraulics to raise the module chain or chain mount plate that requires adjustment. Position
a suitable block or stand to support the arm. Using the tractor hydraulics, lower the machine until the
height adjusting chains are loose.
2. Remove spring retaining clip. Slide chain up to the top of the slot in lifting arm to pass the chain through
the cross at top of plate.
3. Slide chain back down to the bottom when the desired position is reached. To achieve “one link” of
adjustment, lift chain to the top of the slot, pass one link through the slot and rotate 90 degrees to allow
the next link in the adjusting chain to lower into the same slot.
To achieve “half link” of adjustment lift the chain to the top of the slot and slide chain horizontally and
lower the same link into the second slot. This will raise or lower the chain mount plate by half a link
depending on which slot the chain started in. Any excess chain can be fed back through the second slot.
4. Install retaining clip. Remove stand.

Maintenance and Inspection
Good maintenance is your responsibility
• Before working on your machine, ensure all moving parts have stopped
• Always use a safety support and block the wheels
• Use extreme caution when making adjustments
• Replace shields and guards after servicing and before moving
• After servicing, make sure all tools, parts and service equipment are removed
• Where replacement parts are necessary for periodic maintenance and servicing, genuine factory
parts must be used. Kelly will not guarantee the use of unapproved parts and other damages as a
result of their use and will not be liable for injury or warranty if equipment has been altered in any
way
• An appropriate fire extinguisher and first aid kit should be kept readily available while performing
maintenance.
