  • Page 58: Preparation & General Precautions

    NEW MACHINES: PREPARATION & GENERAL PRECAUTIONS IMPORTANT: Always read the book first before attempting to operate the machine – practise operating the machine, without the rotor running, in a safe open space until you are fully familiar with all controls and functions of the machine. Only begin using the machine for work when you are confident that you have mastered the controls and operation sufficient for safe use of the machine.
  • Page 59: Breakaway

    BREAKAWAY The machine is fitted with a hydraulic breakaway device which protects the structure of the machine should an unforeseen obstacle be encountered. The breakaway function does not relieve the operator of his responsibility to drive carefully. Always stay 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 60: Powered Slew

    POWERED SLEW The slew feature allows a 108° arc of powered arm movement on the working side, from right angles to the tractor, to 18° beyond the direct line astern. This feature is required to place the machine in the transport position but can also be used to sweep the arm ‘to and fro’...
  • Page 61: Vfr Arm Operating Caution

    VFR ARMS – OPERATING CAUTION The advanced manoeuvrability that VFR armsets offer permits cutting attachments to be positioned extremely close to the rear and working side of the tractor; this increases the opportunity of tractor and machine to suffer accidental damage from each other. Apply extreme caution whilst operating the armset close to the tractor and keep at a safe distance.
  • Page 62 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.
  • Page 63: Transport Position

    TRANSPORT POSITION The machine is transported inline to the rear of the tractor with a minimum of 300mm (12”) clearance between the tension link and the rear cross member of the tractor cab. 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 64: Transport Locks

    TRANSPORT LOCKS (SLEW & LIFT LOCKS) Slew Lock All machines with slewing capability are fitted with a slew lock – depending on the particular machine this will either be in the form of a lock tap fitted to the slew ram or a slew locking pin that locates through the pillar into the top of the mainframe.
  • Page 65: Transporting The Machine

    TRANSPORTING THE MACHINE In transport the PTO must be disengaged and the power to the control box switched off. The acceptable speed of transport will vary greatly depending upon the ground conditions. In any conditions avoid driving at a speed which causes exaggerated bouncing as this will put unnecessary strain on the tractors top hitch position and increase the likelihood of the tension link contacting the cab rear cross member.
  • Page 66 MOVING FROM TRANSPORT TO WORK Reverting to the work position is basically a reversal of the previous work to transport procedure. Always remember to release the slew and lift locking devices before attempting to move the machine from the transport position. Engaging Drive Ensure the rotor control lever/switch is in the ‘stop’...
  • Page 67: Lift Stop Kit (Option)

    LIFT STOP KIT (Option) For additional machine and tractor protection an optional Lift Stop Kit (Part No. 22493.03) is available. The kit, which hooks over and bolts to the machine’s pillar, is adjustable to suit a wide range of differing applications; when correctly adjusted in its respective positions it will offer both tractor cab protection during transportation and machine components protection when working the arms in and out of positions that risk components coming into contact with each other.
  • Page 68: Easy Drive System

    EASY DRIVE SYSTEM (EDS) The Easy Drive System (EDS) is an optional extra on larger proportional machines with V4 digital controls – where fitted it provides ‘hands free’ cruise control operation with automatic head and lift float at greater working speed that increase both safety and efficiency.
  • Page 69: 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 71: 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 72 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. Find out the location and route of all Power Lines within the work area.
  • 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: 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 75: Maintenance

    MAINTENANCE General Lubrication All points shown above should be greased on a daily basis and prior to storage of the machine. New machines must be greased prior to first use. Gearbox Lubrication Check gearbox oil level on new machines prior to first use, top up if required before using the machine.
  • Page 76 Oil Changes Drainage of the gearbox for changes of oil is via the drain plug located on the base of the gearbox, ensure gearbox is level and allow sufficient time for all the oil to drain out before replacing the plug. For refilling or for ‘topping up’ the oil remove both the filler plug and the level plug;...
  • Page 77 SERVICE SCHEDULE Every Day  Grease machine fully prior to work (and prior to storage). NOTE: New machines must be greased before initial use.  Check for broken or damaged flails.  Check tightness of flail nuts and bolts.  Visually check for oil leaks and damaged hoses. ...
  • Page 78 HYDRAULIC SYSTEM Oil Supply Check the oil level in the reservoir daily. Oil Condition & Replacement No fixed time period can be quoted for oil changes as operating conditions can vary widely but a visually inspection of the oil will often indicate its current overall state. Signs of a reduction in its condition will be apparent by changes in colour and appearance when compared to new oil.
  • Page 79 The breather pressurises the fluid trapped in the tank up to 0.3Bar; this is to reduce pump cavitation and reduces the air flow through the breather - extending the filter life. To avoid danger; unscrew the breather two revolutions and then wait until pressure in tank is equal to the atmosphere - the breather can then be removed safely.
  • Page 80 All Hydraulic Hoses (BSP) now fitted to McConnel Power Arm Hedge/Grass Cutters have ‘Soft Seal’ connections on both flail and ram circuit hoses.
  • Page 81 CABLES The cables operate on a push/pull system with the spool centring springs always returning the spool to the neutral position when the handle is released. Care should be taken during installation and operation to ensure that the cables are not trapped or kinked.
  • Page 82 PTO SHAFT PTO Shaft Lubrication The PTO shaft should be lubricated on a regular basis using lithium based grease – each end of the shaft has 2 greasing points; one for lubrication of the universal joint and one for lubricating the rotating fixing ring of the shaft shield – access to the lubrication points is gained by releasing the shaft shield from its fixing ring and sliding it back along the body of the driveshaft –...
  • Page 83 TELE ARM WEAR PADS Over a period of time during normal use the contact faces of the replaceable wear pads will erode due to friction generated from the sliding surfaces of the tele arm – the wear rate of these nylon compound pads may vary considerably and will be determined by the frequency of use of the telescopic function.
  • Page 84 With the dipper arm socket and telescopic dipper separated coat the inner surfaces of the socket arm and outer surfaces of the tele arm with wax oil prior to re-assembly this will serve to both protect and lubricate the arms - this procedure should be performed in a clean and dry dust free environment to ensure the lubricated sliding surfaces of the arms do not become contaminated by dirt, grit or moisture.
  • Page 85 When tightening second sets of nuts the first nuts should be held in position with a spanner to ensure their correct torque setting is retained. The tele arm should now be extended out to its furthest point and a coating of good quality agri-grease applied to its sliding surfaces.
  • Page 86 TORQUE SETTINGS FOR FASTENERS The chart below lists the correct tightening torque for fasteners. This chart should be referred to when tightening or replacing bolts in order to determine the grade of bolt and the correct torque unless specific torque values are assigned in the text of the manual. Recommended torque is quoted in Foot-Pounds and Newton-Metres within this manual.
