        • 10. Check that the rotor control valve is in the STOP position.
        • 11. With PTO engaged on Ti model or with tractor external services activated on Si model, select “Lift Down”. This will level the frame and enable the lower yoke pins to be fitted. Select the hole which will, as near as possible position the PTO ...
        • 12. Lower the quadrant lever so that the machines weight is taken by the yoke.
        • 13. Adjust the top link to bring the pillar upright.
        • 14. Carry out final adjustment of the tractor lift arm leveling box to bring the main frame horizontal. This should be checked with the arms at approximately half reach with the flail head clear of the ground.
        • 15. Tighten up the check chains or adjustable stabilizers to hold the machine rigid without side-sway.
        • 16. Remove the parking feet, turn inward 90 degrees and relocate in their housings.
        • 17. Carefully operate the machine through its full range of movement while checking that the hoses are not strained, pinched, chaffed or kinked and that all movements are functioning correctly.

    • 1. Ensure that the rotor control is in “STOP” position, start the tractor, engage PTO and allow the oil to circulate for about 5 minutes before operating the arms.
    • 2. Operate the armhead levers through their complete range ensuring that all movements are functioning correctly.
    • 3. Check that the flail nuts and bolts are tight. Place the flail head at a safe position and move the rotor control to “ON” position. After initial fluctuation due to priming, the rotor should settle to a steady speed. Increase PTO speed to appr...
    • 4. Check the hose runs and observe that they are free from any pinching, chafing, straining or kinks. Recheck the oil level in the tank and top up as necessary.
  • PA92 Si
    • 1. Ensure PTO lever is in neutral position, and isolate tractor hydraulic linkage. Start the tractor and select external service supply on the hydraulic controls. Allow the tractor to run for several minutes before attempting to operate any of the ma...
    • 2. While operating, move the levers through their complete range ensuring that all movements are functioning correctly.
    • 3. Check the tractor rear axle oil level and top up if necessary.
    • 4. Place the flail head at a safe position and bring tractor engine revolutions to 1000 RPM to avoid stalling when the starting load is placed on the motor. Engage PTO and allow the rotor to run for several minutes. Do not leave the tractor cab or al...
    • 5. After running up the machine, increase PTO speed to approximately 360 RPM. Run machine further for five minutes before disengaging the PTO and stopping tractor. The reason for this running period under a no load condition is to thoroughly circulat...
    • 6. Check the hose runs and observe that they are free from any pinching, chafing, straining or kinks. Recheck the oil level in the tank and top up as necessary.
• REMOVAL FROM TRACTOR

  • 2. Remove the parking feet, turn through 90 degrees and relocate in their housings.
  • 3. Unscrew the lift ram tap and with the machine at approximately half reach in normal working position, i.e. not broken back. Operate the hydraulic services until the flail head roller is horizontal and level with the feet of the main frame.
  • 4. Disengage tractor PTO and remove.
  • 5. Disconnect stabilizers bars or loosen check chains as applicable.
  • 6. Unbolt the control unit from the mounting pillar, remove from tractor cab and stow in a suitable location clear of the ground. On Si models only, the supply and return hoses must be disconnected from the tractor and stowed with their ends covered ...
  • 7. Raise the machine on the tractor’s linkage to take the weight off the yoke and remove the lower yoke pins.
  • 8. Lower the tractor draft links and place machine firmly on the ground.

    • MAINTENANCE SECTION
  • LUBRICATION
    • 1. Power take-off shaft - The PTO shaft should be regularly examined to ensure that it is in good condition together with the guards. The universal joints should be greased very sparingly, i.e., one shot a week.
    • 2. The two halves of the plastic guard should be checked daily to ensure that they can spin freely on the shaft. The nylon slip rings which support the guard on the drive shaft should be lightly greased at weekly intervals.
    • 3. The telescoping drive shaft should be similarly separated and grease applied to the internal shaft at approximately 100 hour intervals.
• HYDRAULIC SYSTEM
  • Oil Supply
    • 1. Cleaning off around the reservoir cap before removal, and keeping that area clean.
    • 2. Using clean containers when replenishing the system.
    • 3. Regular servicing of the filtration system.
  • Filtration Maintenance
    • 1. Suction Strainer
    • 2. Return Line Filter
  • HYDRAULIC HOSES
    • Hose Replacement
      • 1. Replace one hose at a time to avoid the risk of wrong connections.
      • 2. When the hose is screwed to an additional fitting or union, use a second spanner on the union to avoid breaking both seals.
      • 3. Do not use jointing compound on the threads.
      • 4. Avoid twisting the hose. Adjust the hose line to ensure freedom from rubbing or trapping before tightening hose end connections.

  • P.T.O. GEARBOX
• FLAILHEAD
  • 1. Frequently inspect the rotor assembly for damaged or missing flails. Bolts and nuts securing the flails to the rotor should be regularly checked and kept tight. The correct torque setting for these locknuts is 135 Nm (100 lbs/ft.). Use only the co...
  • 2. Do not attempt to run the rotor with flails missing. Imbalance will cause severe vibration and can rapidly damage the rotor shaft bearings. As an emergency measure, if a flail is broken off or lost, remove another on the opposite site of the rotor...
  • 3. Blunt flails absorb a lot of power and leave an untidy finish to work. They should be sharpened on a grindstone or with a portable grinder periodically.
  • 4. Wear protective gear when sharpening flails.
  • 5. Ensure that the bearing housings and hydraulic mounting nuts and bolts are kept tight. They should be checked during servicing.
