To clean the dry--type induction air filter:
1.
Remove engine cowling.
2.
Remove filter element.
3.
Direct a jet of air from inside of filter out (opposite normal airflow). Cover entire filter
area with air jet.
--CAUTION--
Do not use a compressor unit with a nozzle pressure greater than 100 PSI.
4.
After cleaning, inspect filter for damage. Discard if filter or gasket is damaged.
NOTE:
If filter shows an accumulation of carbon, soot, or oil, continue with cleaning
steps “5” through “8.”
5.
Soak filter in non--sudsing detergent for 15 minutes; then agitate filter back and forth
for two to five minutes to free filter element of deposits.
NOTE:
A Donaldson D-1400 Filter Cleaner is also recommended. Do not use solvents.
6.
Rinse filter element with a stream of clear water until rinse water is clear.
7.
Dry filter thoroughly. Do not use a light bulb or air heated above 180
o
F. for filter drying.
8.
Inspect for damage and ruptures by holding light bulb inside filter. If damage is evident, replace
filter with a new one.
GEAR & TIRES
The aircraft is equipped with 6-ply, Type III, standard--brand tires and tubes. Keep main gear tires
inflated at 42 PSI and the nose tire at 49 PSI for maximum service life. Proper inflation will mini-
mize tire wear and impact damage. Visually inspect tires during pre-flight for cracks, ruptures
and worn spots. Avoid taxi speeds that require heavy braking or fast turns. Keep the gear and
exposed gear retraction system components free of mud and ice to prevent retraction interfer-
ence and binding. It is recommended that retraction/extension cycles (5 minimum) be done any
time any tire is replaced to assure that no interference exists during the cycle.
--CAUTION--
After any landing, other than a smooth touchdown and rollout, when aircraft is
above 3200 Lbs (1,452 Kg), the aircraft should undergo the Gear System Opera-
tional Inspection as outlined in M20TN Service and Maintenance Manual,
Chapter 32.
The gear warning VOICE ALERT may be checked in flight by retarding throttle with the gear up.
The gear warning VOICE ALERT should sound when throttle is positioned 1/4 to 3/8 inch from
idle (while gear is up).
BATTERIES
The two 24-volt, 10 ampere-hour electrical sealed storage batteries are located in the tailcone,
aft of baggage compartment bulkhead, accessible through left and right side tailcone access
panels.
To service batteries, remove tailcone access cover(s) to gain access to battery(ies). Check ter-
minals and connectors for corrosion.
Keep battery at full charge to prevent freezing in cold weather and to prolong service life.
