Operation - Cessna TR182 1979 Pilot Operating Handbook

SECTION 4
NORMAL PROCEDURES
CESSNA
MODEL TR182
2. Propeller -- CLEAR.
3. Avionics Power Switch -- OFF.
4.
Master Switch -- ON.
5. Throttle -- CLOSED until engine starts.
6. Ignition Switch -- START (release to BOTH when engine starts).
Without Preheat:
1. Prime the engine two to four strokes with mixture full rich and
throttle closed.
2. Propeller -- CLEAR.
3. Avionics Power Switch -- OFF.
4. Master Switch -- ON.
5. Throttle -- CLOSED until engine starts.
6. Ignition Switch -- START.
7. Release ignition switch to BOTH when engine starts.
8. Oil Pressure -- CHECK.
9. Primer -- LOCK.
NOTE
If the engine does not start during the first few attempts, or
if engine firing diminishes in strength, it is probable that
the spark plugs have been frosted over. Preheat must be
used before another start is attempted.
NOTE
Pumping of the throttle will make starting more difficult
due to a rapidly varying mixture. The carburetor is not
equipped
w
i t.h an accelerator pump.
OPERATION
During cold weather operations, no indication will be apparent on the
oil temperature gage prior to takeoff if outside air temperatures are very
cold. After a suitable warm-up period (2 to 5 minutes at 1000 RPM),
smoothly accelerate the engine several times to higher engine RPM. If the
engine accelerates smoothly and the oil pressure remains normal and
steady, the airplane is ready for takeoff.
Rough engine operation in cold weather can be caused by a combina-
tion of an inherently leaner mixture due
to
the dense air and poor
vaporization and distribution of the fuel-air mixture
to
the cylinders. The
effects of these conditions
are especially noticeable during operation
on
one magneto in ground checks wh er-e only one spark plug fires in each
cylinder.
