To Inflate Tires
1. Open access doors on wheel pants to gain access to valve stems. It may
be necessary to move airplane to get valve stem aligned with the access
hole.
2. Remove valve stem cap and verify tire pressure with a dial-type tire
pressure gauge.
3. Inflate nose tire to 30 - 35 psi (207 - 241 kPa) and main wheel tires to
60 - 65 psi (414 - 448 kPa).
4. Replace valve stem cap and close access doors.

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.
Refer to the shot peening requirement described in
"Propeller".

Engine Oil Servicing

The oil capacity of the Continental Motors IO-550-N engine is 8 quarts.
It is recommended that the oil be changed every 50 hours and sooner under
unfavorable operating conditions.
Engine Break-In: For first 25 hours of operation or until oil consumption
stabilizes, use straight mineral oil conforming to MIL-C-6529. If engine oil
must be added to the factory installed oil, add only MIL-C-6529 straight
mineral oil.
