CAUTION
e
If the primer is activated for excessive
periods of time with the engine inoperative
on the ground or during flight, damage may
be incurred to the engine and/or aircraft
due to fuel accumulation in the induction
system.

when the engine is shutdown with the aux-
iliary fuel pump ON.

occur, the engine manifold must be purged

the drain under the nacelle.
(b)

draining periods recommended above,
with the auxiliary fuel pump OFF,
magnetos OFF, mixture idle cut-off and
throttle full open, turn engine with
starter or by hand a minimum of 15
revolutions.
