REPLACEMENT AND ADJUSTMENT OF BLADES
When replacing a single blade the blade must be placed at the same distance to the
shear-bar as the existing blades. To ensure that the rotor is in balance it may be
necessary also to replace the opposite blade as a used blade has a different weight
compared to a new blade.
Even if there is no visible damage to the blade bolts, they should always be replaced
together with the blades as they might have been overloaded.
CAUTION: Check the distance between the blade and the shear-bar (0.5
mm) with the supplied gauge before the bolts are tightened.
WARNING: Only use original blade bolts when replacing. Tighten the blade
bolts with a torque wrench to 40 kgm or with the supplied
spanner using approx. 40 kg leverage.
Fig. 4-24 When the blades have been worn max. 8 mm or to the first bend, i.e. approx. 12 mm
above the straight piece, they must be replaced.
DANGER: When all blades on the rotor have been worn and the rotor
adjusted towards the shear-bar, it MUST be adjusted back again
before new blades are mounted. Otherwise there is a risk that
the new blades collide with the shear-bar when the rotor is
turned.
