Page 44: Operator Guard
OPERATION Operator Guard Machine Guards Before each period of work, check that all the relevant tractor and machine guards are in place and in good working condition. Small splits and abrasions on the lower edges of the flail head rubber flaps are permissible, but should one or more of these cuts or splits become fifty per cent or more of the flap height they should be replaced immediately as they will have become ineffective for debris containment. -
Page 45: Pre-Work Preparation & Precautions
PRE-WORK PREPARATION & 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 46 ‘Running In’ a New Machine For the first day’s work with a new machine it is recommended that tractor forward speed is restricted to 3 km/hr. (2 mph) maximum. This will allow machine components ‘bed in’ and allow the operator to become familiar with the controls and their response under working conditions whilst operating at a relatively slow speed.

Page 65: 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 66: Vfr Operating Caution
VFR ARMS – OPERATING CAUTION The advanced manoeuvrability that VFR armset s offer permits cutting att achments to be positioned extremely close to t he rear and working side of the tractor; this increases the opportunity of tractor and machine to suffer accidental damage from each other. Apply extr eme caution whilst operating the arms et cl ose to the tractor and keep at a safe distance. -
Page 67: Powered Slew
POWERED SLEW The slew feature allows a 100° arc of powered arm movement on the working side of the tractor – from the position at right angles to the tractor rearwards to 10° 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 68: 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 –... -
Page 69: Easy Drive System (Eds)
EASY DRIVE SYSTEM (EDS) The Easy Drive System (EDS) is an optional extra on larger proportional machines with V3, 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 70: Parallel Arm Geometry
PARALLEL ARM GEOMETRY Parallel Arm Geometry This feature enables the operator to adjust the 'in and out' reach of the machines arms, without the need to continuously adjust the 'lift' service in order to compensate for the change in head pivot height - as would be the case with conventional arm geometry. The performance of this feature is at its most accurate during the mid-range of the reach travel, with some deterioration in performance being experienced when the outer extremities of reach adjustment are approached. -
Page 71: Telescopic Dipper Arm
TELESCOPIC DIPPER – PA6500T /PA7700T / PA8000T PA6500T / PA7700T / PA8000T models are equipped with telescopic dipper arms giving them extended reach capabilities. In normal working conditions, the 'tele' will be pre-set and the machine operated using the controls in the normal manner - the tele function mode can be used as an alternative to 'reach' but a slower response to the commands must be expected. -
Page 72: Moving Into Transport Position
MOVING INTO TRANSPORT POSITION Select 'Rotor Off' and wait until the rotor has stopped turning. Ensure that the lift and angle float are switched off and, on tele models operate 'Tele In' and fully retract the telescopic arms. Select ‘Slew’ mode on the controls and operate ‘Slew In’... -
Page 73: Transport Position
TRANSPORT POSITION The machine is transported in line to the rear of the tractor with a minimum of 300mm clearance between the tension link and the rear cross member of the tractor cab. Transport Position with Flailhead Removed With the flailhead removed the arms are fully folded but the lift ram remains fully retracted. If the lift ram is extended the weight of the arms will cause the balance of the machine to go ‘over centre’... -
Page 74: Transport
TRANSPORTING THE MACHINE Transport Height There is no fixed dimension for the transport height as this will vary for differing models and 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 4.1m height will fall within the region of approximately 4.1m to 4.4m. -
Page 75: Cab Protection System (Option)
CAB PROTECTION SYSTEM (Option) The cab protection system safeguards the rear crossmember of the tractor cab from possible damage caused by the arms coming into contact with it during transportation or when the arms are being manoeuvred directly behind the tractor. The system consists of a ‘shoe stop’... -
Page 76: Slew & Lift 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 78: Tractor Forward Speed
Tractor Forward Speed The material being cut will determine the tractor forward speed. Forward speed can be as fast as that which allows the flail head sufficient time to cut the vegetation both efficiently and neatly. If forward speed is too fast this be indicated by over frequent operation of the breakaway system, a fall off in tractor revs and a poor untidy finish to the work leaving ragged uncut tufts and poorly mulched... -
Page 79: 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 80 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 87 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 88 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 89 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.
