9.3 Propeller replacement
Before you do anything with the propeller, ensure that the cables to the battery are
disconnected.
You can remove the propeller simply by loosening and removing the nuts using a
special key included in the scope of supply. It is necessary to hold the propeller by hands
while loosening the nuts, so that the propeller would not rotate. Never attempt to loosen
the nut with a hammer or a similar tool, as this may cause damage to the lock nut and the
shaft of the motor. After removing the lock nut you can remove the propeller.
When re-installing the propeller into its place, align the slots and grooves of the
propeller and the shaft, otherwise the propeller won’t be locked in place.
