context key. This
action automatically erases the former reading.
CAUTION: Pressing
GO BACK
cancels (undoes or erases) the

NOTE: High-horsepower, coarse pitch propellers may stall at a
maximum static RPM. Do not attempt a balance with the propeller

inaccurate. A propeller is stalling if there is a noticeable change in
the propeller’s sound, from what the user normally hears.
