3. Before inserting the bolts, lubricate the stable with thin layer of grease. We recommend
using white silicon grease (use only clean grease, from closed tube). Then insert such
lubricated bolts to each propeller blades bushing, from each side, so that thin film of the
grease will be also transferred to inner surface of bushing. Clean away any exceed amount
of grease. If there is too much grease, it will be later spilled to inner surface of the spinner
by centrifugal force, so we recommend using only a minimum amount of grease. Take out
the bolts, and put them on clean surface, to be ready for assembly.
4. Align propeller blade so that its fixing hole is nicely aligned with hole of propeller holder.
From back side of the holder, insert lightly lubricated, special bolts.
This means that
head of the bolt must be on trailing edge side of propeller as on picture below!
One of the two special bolts is
marked
on the head with a small dot. Be sure to install it
to proper side of propeller holder which is marked with small dot.
5. Before placing washers, crown nuts, and split pins, it is strongly recommended to close
motor openings with a tape, as show on photo above in order to reduce possibility that
any of the small parts could enter into the motor, if it falls through the fingers by
coincidence. If this would happen, it is usually necessary to remove and open motor,
which is quite demanding job, so it is better to tape openings.
