The advantage here is that the hedge will be as thick as possible to resist debris flying through it onto the road. The side(s), top and then the bottom can then be cut from the roadside.
  • Page 108 Cutting head 1 meter If the obstruction has still not been removed it’ll need removing manually. Ensure that the cutting head is lowered to the ground or supported in such a way that hydraulic or mechanical failure cannot injure any personnel. Position the Cutting head vertically upright so the rotor can be accessed.
  • Page 109 On HD700 trimmer controls an auto-return function is fitted as standard. With auto- return switched on the machine senses if the booms have broken back and if so automatically returns them to the working position.

  • Page 110: Telescopic Arm

    7.15 TELESCOPIC ARM See section 2.7 for accident prevention when operating. Telescopic outer arms are an option on HD700 trimmers. These give an extra 1.2m (6.0mT), 1.5m (7.0T) or 1.83m (8.0T) of horizontal reach, which can be useful for high hedges, deep or wide ditches and banks, while still keeping a compact arrangement for close work when closed-in.
  • Page 111 7.17 NARROW LANE BRACKET See section 2.7 for accident prevention when operating. Narrow lane bracket is an option on all models. This feature allows the head to rotate up 53 degrees using the tractor spool valve (see section 6). Using the narrow lane bracket enables the operator to tuck the trimmer booms and head behind the tractor wheel when cutting the side of a hedge when working within narrow lanes.
  • Page 112 When the narrow lane bracket is not being used it can be locked in its fully closed position by inserting the locking pin and retaining with the pin into the hole nearest the pin handle. Locking pin To unlock the narrow lane bracket with draw the locking pin, then fit the retaining pin in the locking...
  • Page 113 Set the valve to fully open, fully anti-clockwise To ensure the fan is running smooth turn the tractor spools flow down to between 20 – 30 l/min or if the fan blower is hunting turn the tractor spool flow down until it runs smooth.
  • Page 114 Lowest height OHPLs are those carrying 11kV to 33kV at a minimum height of 5.2 meters above ground. HD700 trimmers are capable of reaching higher than 8 meters which means there is high risk of the machine being able to contact the wires.
  • Page 115 Exclusion zones are shown in shaded area below. Exclusion Exclusion zone Exclusion zone zones for high voltage low voltage (LV) pole with (HV) transformer Never allow any part of the machine to enter the exclusion zone. Operation of any part of the Powerblade or tractor within 10 meters horizontally of an OHPL is not recommended.

The gearbox is prefilled with a Synthetic gear oil, grade SAE 75W-90. Brands of oil recommended are – Total SYN FE 75W90, BP Energear SHX SAE 75W- 90 or Mobilube SHC SAE 75W-90.

  • Page 119: Hydraulic Oil

    If a biodegradable oil is to be use, please contact Shelbourne Reynolds Ltd with the oil specification to check suitability. The interval at which the oil should be renewed will depend on the way in which the oil is worked and how well it is looked after.
  • Page 120 The machine is also fitted with an oil cooler located at the top of the oil tank. This should be cleaned out regularly using high pressure air as the cooler matrex may become blocked from dust and debris. To clean out the oil cooler unscrew the three M8 fasteners enabling the steel cover to be removed.

    after every 500 hours. Note that if the filter is allowed to become clogged then the oil will bypass the filter (to avoid the danger of the filter bursting) and could allow contaminants into the tank and hence into the system components. If another hydraulic component has failed then the return filter should also be renewed forthwith.
  • Page 122 ACCUMULATOR SAFE REMOVAL Refer to section 2.6 for accident prevention when using the hydraulic system The accumulator must be pressurised for the lift float to function correctly. If the tap has been moved to the de-pressurised position the head will constantly drop to the ground even if the lift float is not engaged.

  • Page 123: Flail Head

    Every machine has a rotor balance sheet supplied in its manual canister from new. If the balance sheet is missing contact Shelbourne Reynolds who hold a copy and will re-issue the balance sheet upon quoting the machine’s serial number.

Flail bolt longer versions used (105mm, 115mm & 130mm) Balance weight versions 20g (2mm), 30g (3mm) & 50g (5mm). Replace spacers, bolts and nuts exactly when replacing flails. The flails themselves should wear evenly and be replaced as a set.
  • Page 125 All HD700 cutting heads are belt driven, check the belt tension daily. This requires the removal of the drive cover. Loosen fixings to remove drive cover Note – Fixings are captive on drive cover A load of 5 Kgs (10lbs) should give a deflection of approximately 9mm at the mid span.

In the unlikely event these are subjected to extreme wear they should be renewed promptly to reduce shocks, keep movements predictable and protect the underlying steel. 8.12 RECOMMENDED TORQUE SETTING FOR FASTENERS Refer to section 2.10 for accident prevention when servicing/adjusting the machine The table on the next page gives correct torque values for various size and grade of...
  • Page 127 8.13 STORAGE Refer to section 2.12 for accident prevention when cleaning and storing the machine Clean the machine thoroughly, making sure that high-pressure water does not contact bearings, seals or electrical components. Avoid washing paintwork at very close range or with very high pressure. Release the tension in the drive belts, but replace the drive cover to keep the light out.
