  • Page 67: Breakaway

    BREAKAWAY The machine is fitted with a hydraulic breakaway device which protects the structure of the machine should an unforeseen obstacle be encountered. NOTE The breakaway function does not relieve the operator of his responsibility to drive carefully, be alert and AVOID OBVIOUS HAZARDS BEFORE CONTACT OCCURS. Breakaway may occur momentarily during normal work should an extra thick or dense patch of vegetation be encountered.
  • Page 68: Powered Slew

    POWERED SLEW The slew feature allows a 95° arc of powered arm movement on the working side from right angles to the tractor to 5° beyond the direct line astern. The feature is required to place the machine in the transport position but can also be used to sweep the arm to and fro whilst cutting awkward areas and corners thus avoiding the need to constantly re-position the tractor.
  • Page 69: Moving Into Transport Position

    MOVING INTO TRANSPORT POSITION Select ‘Rotor Off’ and wait for the rotor to stop turning completely. Ensure that both ‘lift’ and ‘angle float’ functions are switched off. Select ‘slew’ mode on the controls. Operate ‘slew in’ function to bring the arms into position directly behind the tractor.

Transport Position with Flailhead Attached Transport Position with Flailhead Removed For transportation without a flailhead attached, the machines arms must be fully folded and the lift ram fully retracted so the mass of the arms is behind the centre line –...
  • Page 71: Transporting The Machine

    TRANSPORTING THE MACHINE Transport Height There is no fixed dimension for the transport height as this will vary for differing applications i.e. tractor size, carrying height, and degree of arm fold the particular tractor cab will permit. For the majority of installations the transport height will be in the region of approximately 3.45m to 3.65m.
  • Page 72: Operating Speeds

    OPERATING SPEEDS PTO Operating Speed The correct PTO speeds for operation of machines is: 500 - 540 rpm (Max) WARNING: Damage to the machine may occur if the maximum PTO speed is exceeded. Engaging Drive Ensure the rotor control lever/switch is in the ‘stop’ position before engaging the PTO. Allow the oil to circulate for a minute or so before operating the armhead controls.
  • Page 73: Hazards & Dangers

    HAZARDS & DANGERS Adverse Slopes When working with the flailhead high and reach fully in it is possible for the main arm balance to go over centre and take the weight off the lift ram. A restrictor in the gland circuit of the lift ram will prevent sudden unpredictable movements if this should occur - for reasons of safety this restrictor should not be removed.
  • Page 74: Overhead Power Lines

    OVERHEAD POWER LINES (OHPLs) It cannot be stressed enough the dangers involved when working in the vicinity of Overhead Power Lines (OHPLs). Some of our machines are capable of reach in excess of 8 metres (26’); they have the potential to well exceed, by possibly 3 metres (9’ 9”), the lowest legal minimum height of 5.2 metres from the ground for 11,000 and 33,000 volt power lines.
  • Page 75 Definitions of Exclusion Zones Risk Assessment Before starting to work near OHPLs you should always assess the risks. The following points should be observed;  Know the risks of contacting OHPLs and the risk of flashover.  Find out the maximum height and maximum vertical reach of your machine. ...
  • Page 76: Hedgecutting Procedure

    HEDGECUTTING PROCEDURE Cut the side and bottom of the field side first. This leaves the maximum thickness of hedge on the road side to prevent the possibility of any debris being thrown through the hedge into the path of oncoming vehicles. Cut the side and bottom of the road side.
  • Page 77: Lift Float (Option)

    LIFT FLOAT (Optional Extra for Ground Work) Work without lift float requires far more concentration and input from the operator to quickly react and re-adjust to the ground contours often resulting in patches of higher cut material where the head is cutting too high and ‘scalping’ of the ground where it is cutting too low –...
  • Page 78: Angle Float

    ANGLE FLOAT KIT (Standard Feature) Machines are fitted with Angle Float as standard – when activated the feature connects the base and gland circuits of the angle ram to allow free movement of oil in both directions thus allowing the head to automatically angle itself to match the contours of the ground. Refer to specific controls section for details of operation.
  • Page 79: Maintenance

    GENERAL MAINTENANCE General Lubrication The example illustration below indicates the general locations of lubrication points - all points should be greased on a daily basis and prior storage of the machine.
