If
an
obstruction
ahead
requires a steep climb angle, the airplane
should
be
flown
at
the
all
engines best angle-of-climb speed with
wing
flaps
up
and
maximum
nonnal
operations
power.
This speed varies
from
84
KIAS
at
sea level
to
88
KIAS
at
16,000
feet.
During
cruise climbs, positioning the propeller synchrophaser to
PHASE
will eliminate the unpleasant audio beat
accompanying
unsynchronized opera-
tion.
The
propeller synchrophaser
can
also
provide a
significant
reduction
in
cabin vibration.
With
the propellers
slightly
out of synchronization so that
an
audio
beat
is
obtained approximately once
each
5 seconds,
it
should
be
noted that
the vibration level of the cabin
and
instrument
panel
will
increase
and
decrease
at
a rate
of
approximately
once
each
20
seconds.
Optimum
opera-
tion
wi11
be
obtained
by
manually synchronizing the propellers
and
posi-
tioning the synchrophaser switch
to
PHASE.
Best propeller synchronizing
is
obtained
by
making
the final adjustment of the propeller controls in a
DECREASE
RPM
direction.
For
best operation, securely tighten the quadrant
friction
lock to prevent the slaved propeller control fran creeping.

If
oxygen
use
is
desired, proceed as follows:
a.
Mask
-
Connect
mask
and
hose assembly
and
put

.
....-----IWARNING.---
.....
Pennlt
no
smoking
when
using oxygen.
Oil,
grease,
soap,
lipstick,
lip
balm,
and
other
fatty
materials
constitute
a serious
fire
hazard
when
in
contact
with oxygen.
Be
sure
hands
and
clothing are
oil-
free before handling
oxygen
equipment.
