4.1 Propeller and Spinner Installation

WARNING! DO NOT OPERATE THE ENGINE /
PROPELLER WITH ONLY THE SPINNER FILL-
IN PIECES INSTALLED!

IF THE ENGINE AND PROPELLER ARE TO BE RUN
WITHOUT THE SPINNER DOME INSTALLED IT IS
IMPARATIVE THAT THE FILL-IN PIECES ALSO BE
REMOVED. The centrifugal force will damage or destroy the
fill-in pieces without the support of the spinner dome. (The
engine and propeller can be operated with only the spinner
rear bulkhead installed.)

* For safety reasons always turn the propeller opposite
of the usual direction of rotation.
