MINOR MAINTENANCE

RUBBER SEALS

To prevent sticking of the rubber seals around the windows,
doors, and engine cowling, the seals should be coated with
Oakite 6 compound. The compound is non injurious to paint
and can be removed by employing normal cleaning methods.

HEATING AND VENTILATING SYSTEM

The heater fuel pump filter in the nose wheel well should be
removed and cleaned after each 100 hours of airplane opera-
tion. Remove the filter by turning the base of the pump coun-
terclockwise. Wash the filter in fresh cleaning solvent (see the
Baron Maintenance Manual) and dry with compressed air.
The iris valve at the heater blower inlet should be lubricated
occasionally with molybdenum disulfide (see the 55/58/G58
Baron Shop Manual). The valve should never be lubricated
with oil or any liquid lubricant which would collect dust.
Do not reset the overheat circuit breaker until a thorough
inspection of the system has determined the cause and the
malfunction has been corrected.

ALTERNATORS

Since the alternator and electronic voltage regulator are
designed for use on only one polarity system, the following
precautionary measures must be observed when working on
the charging circuit, or serious damage to the electrical equip-
ment will result:
1. When installing a battery, make certain that the ground
polarity of the battery and the ground polarity of the alter-
nator are the same.
2. When utilizing an external power source, ensure polarity
of the external power source and polarity of the airplane
electrical system is maintained (Negative to Negative;
Positive to Positive).
