2.
Remove valve stem cap and verify tire pressure with a dial-type
tire pressure gage.
3.
Inflate nose tire to 40 +2/-0 psi (276 +15/-0 kPa) and main wheel
tires to 53 +2/-0 psi (365 +15/-0 kPa).
4.
Replace valve stem cap and inspection buttons.
All wheels and tires are balanced before original installation and the
relationship of tire, tube, and wheel should be maintained upon
reinstallation. In the installation of new components, it may be
necessary to rebalance the wheels with the tires mounted.
Unbalanced wheels can cause extreme vibration in the landing gear.
Propeller Servicing
The spinner and backing plate should be cleaned and inspected for
cracks frequently. Before each flight the propeller should be inspected
for nicks, scratches, and corrosion. If found, they should be repaired
as soon as possible by a rated mechanic, since a nick or scratch
causes an area of increased stress which can lead to serious cracks
or the loss of a propeller tip. The back face of the blades should be
painted when necessary with flat black paint to retard glare. To
prevent corrosion, the surface should be cleaned and waxed
periodically.
Oil Servicing
The oil capacity of the Teledyne Continental IO-360-ES engine is 8
quarts. It is recommended that the oil be changed every 50 hours and
sooner under unfavorable operating conditions. The following grades
are recommended for the specified temperatures at sea level (SL):
An oil filler cap and dipstick are located at the left rear of the engine
and are accessible through an access door on the top left side of the
