The propellers covered by this manual may have a restricted
operating range that requires a cockpit placard. The restrictions,

General
A. Personnel Requirements
Personnel performing maintenance are expected to have
sufficient training and certifications (when required by
the applicable Aviation Authority) to accomplish the work
required in a safe and airworthy manner.
B. Maintenance Practices
(1) The propeller and its components are highly vulnerable
to damage while they are removed from the engine.
Properly protect all components until they are reinstalled
on the engine.
(2) Never attempt to move the aircraft by pulling on the
propeller.
(3) Avoid the use of blade paddles. Do not place the blade
paddle in the area of the de-ice boot when applying
torque to a blade assembly. Place the blade paddle in
the thickest area of the blade, just outside of the de-ice
boot. Use one blade paddle for each blade.
(4) Use only the approved consumables, e.g., cleaning
agents, lubricants, etc.
(5) Observe applicable torque values during maintenance.
