  • Page 74: Vfr 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 75: Easy Drive System (Eds)

    EASY DRIVE SYSTEM (EDS) The Easy Drive System (EDS) is an optional extra on larger proportional machines with V4 or Revolution 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 76: Angle Float & Lift Float

    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 – in the case of the latter this can lead to increased flail wear, damage or even loss of flails.

  • Page 77: Telescopic Arm

    LIFT FLOAT KIT for non EDS machines (Part No. 8126351) The after market lift float kit is mounted to the inner side of the tank as shown in the illustration below left, a mounting plate with threaded holes is provided on the tank for this purpose.

  • Page 85: 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 86: 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 87 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 94: Hydraulic System

    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 95 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 96: Hydraulic Hoses

     Avoid twisting the hose. Adjust the hose line to ensure freedom from rubbing or trapping before tightening hose end connections. 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 101: Tele Arm Wear Pads

    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 102 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 103 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.

    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.
