 WARNING 
If at any time the universal joints have been
disturbed, it is vital that they are correctly aligned
before the Verticutter is used.
Significant damage can result if the machine is
operated with a poorly aligned universal joint
Note : a.
The universals are individually fitted and so must go back in their
original position using the same keys

The two wing blade reels are mirror images; the blades go on the
rotor shaft in opposite directions. If, at any time, both blade reels are
removed from the machine at the same time, be careful to return
each shaft to its’ original position and that the blade orientation is
correct.
