HYDRAULIC CONTROLS - CUTTING POSITION
The cutting head must at all times be lowered gently into the cutting position. Never ‘drop’
a flailhead into a hedge at speed.
When cutting at ground level (grass etc.) the head must be lowered gently to give a slight
contact pressure of roller to ground.
WARNING:
Ensure flailhead does not come into contact with obstacles such as rocks, stones, stumps
etc. Keep rotor away and free from wire, as to entangle wire in a rotor is both dangerous
and costly.
Should large obstacles be encountered or wire become entangled in the rotor
stop
immediately and reset or clear before continuing.
DANGER WARNING
Always stop machine, switch off engine and pocket the key before
attempting to remove any items that foul the flailhead.
Normal obstacles and level variations should be overcome by the operator slowing
'forward motion' and raising/lowering the booms of trimmers to suit.
CUTTING HEAD
The cutting head rotor has been balanced prior to fitting; this will ensure a vibration free
cutting unit.
Should the rotor become blocked for any reason, hit an obstacle, loose a blade or blades,
the rotor may be put into a state of unbalance. This will result in vibration from the rotor
being transmitted through the head. Should this happen
stop immediately , as to continue
may have serious consequences.
Once stopped clean rotor and check for loss of blades and bolts, replace as required.
As a result of hitting solid objects with serious force the rotor can be bent, this will
obviously cause vibrations. In such cases the only answer will be to get the rotor
repaired/rebalanced or replaced.
Keep the cutting blades VERY SHARP: the flailhead should be inspected daily. Bolts and
nuts holding flails to rotor should be
checked frequently and kept tight. Missing or
broken flails should be replaced immediately, as the imbalance will rapidly harm bearings
and structure. When a flail is renewed its opposing flail (or pair if using Back to Back
flails) should be renewed also in order to maintain balance.
Check ‘vee’ belt tension on cutter head daily: a load of 5 Kgs
(10 lbs.) should give a
deflection of 9mm at these pulley centres. Access to the belts is by removing the guard
panel on the side of the drive end. Tension is adjusted by first slackening the bolts
mounting the motor
(nuts are held from turning on the inside). The nuts on the threaded
adjuster can now be turned to give the required tension and then re-tightened and the
motor mounting bolts then tightened also.
