Cessna 210B - Electrical System; Fuel Quantity Indicators; Fuel Strainer Drain Knob; Circuit Breakers

Description
labeled "HI, " operates both pumps
and closes the vapor return line,
supplying sufficient fuel flow to
maintain flight. This position is also
used for vapor elimination.
The auxiliary system is not to be
used during normal operation, be-
cause, with the engine-driven pump
functioning , a fuel/air ratio con-
siderably richer than best power
is produced and any vapor in the
system cannot be returned since the
vapor return line is closed.
NOTE
If electric pumps are turned on
with the engine stopped, intake
manifolds will be flooded unless
the mixture is in idle cut-off.
FUEl QUANTITY INDICATORS.
Two electrically - operated fuel
quantity indicators are provided,
each working in con.iunction with an
electric fuelleyel transmitter in its
respective fuel tank. Turned on by
the master switch, the indicators
continue to function until the master
switch is turned off.
FUEl STRAINER DRAIN KNOB.
The fuel strainer drain knob marked
"STRAINER DRAIN" provides a
quick, convenient method of draining
water and sediment that may have
collected in the fuel strainer. The
strainer is located in the nose wheel
well.
About two ounces of fuel (3 to 4
seconds of drain knob operation)
should be drained from the strainer
before the initial flight of the day t
insure against the presence of wat er
or sediment in the fuel.
The spring-loaded drain valve in
the strainer is open when the fu el
strainer drain knob is pulled out all
the way. The drain valve autom ati -
cally closes when the knob is r e-
leased.
ELE CT RICAL SYSTEM.
Electrical energy is suppli ed by
a 12-volt, direct-current sy s1. cr "
powered by a 50-ampere en gine
driven generator. The 12-vo lt stn l
age battery is located on the U PPI i
right-hand forward portion of II ..
firewall.
