B Reversing the blades of group 2
Rule:
Every blade disk has four blade positions. The blades are positioned at an angle for two
positions
(1)
and the blades are approximately straight for two positions
(2)
. The front side (F) of
the blade must always be directed towards the axis line of the rotor for the slanted blades. One
blade will point
(F)
the front side to the right and the other will point
(F)
the front side to the left
for the straight blades.
Perform the following steps to consistently apply this rule:
• Disassemble two blades that are diametrically oppo-
site each other. Rotate them through 180° and change
them over. Do the same with the two remaining blades.
Repeat this operation for the three remaining blade
disks of group 2.
• Always clean the blades and blade holders before
reinstalling them.
