13.5 Bale Restraint Beam Adjustment And Removal
To adjust the bale restraint beam(s) remove the two M12
bolts located in the holes on both sides of the restraint
beam, and loosen the third bolt in the slot.
the bale restraint beam by aligning the necessary holes,
replace and tighten bolts.
To remove, take the weight of the bale restraint beam
using a suitable lifting device. Remove the 3 bolts from
each end before extracting the bale restraint beam.
Refitting is the reverse of above.
13.6 Dual Chop Sieve Removal
Raise the blade beam and lock it in the upper position by
entering the bale chamber and sliding two bars through
the 19mm (¾") diameter holes in the slides.
Remove the bale restraint beam as detailed above.
Remove the six M10 bolts that hold the sieve to the mid
body panels. Remove the six cup square bolts retaining
the screen to the support beam. The sieve can then be
removed by rolling it over the crossbeater.
Refitting is the reverse of the above.

13.8 Gearbox
Check the oil level in the rotor gearbox and bed chain
drive gearbox (where fitted) monthly.
After 50 hours of use the gearbox oil should be drained

guards, remove the drain and filler plugs and allow it to
empty. Waste oil should be collected and disposed of at
an oil recycling facility approved by the local authorities.
Refill the gearbox with SAE90.EP gearbox oil.
The oil capacity of the gearboxes:
Rotor gearbox 5 litres (1.3 US gallons).
Bed chain gear box 2.5 litres (0.55 US gallons).
