PRECAUTIONS AND SAFETY MEASURES

1 Untighten bolts (Fig. 1, 4) so that bolt heads does not contact outer propeller hub.
2 Unscrew bolts (Fig. 1, 2) about 2 revolutions.
3 Position propeller pitch adjustment tool with the inner side on outer propeller hub and profiled section on the
propeller blade.
4 Carefully adjust blade pitch by tapping with a 200 g rubber hammer in the area of the blade's nose section so
that blade pitch increases or decreases. Never use hammer on trailing edge as the blade may be damaged
that way.

allowing a small light gap between blade's back and the tool's profiled section.
6 Repeat work steps 3 to 5 for the remaining blades.
7 Hand-tighten bolts (Fig. 1, 2) and (Fig. 1, 4) and check blade pitch setting for all blades. If necessary,
untighten bolts and re-do from step 1.
