CARE OF WINDSHIELD AND WINDOWS
A certain amount of care is needed to keep the Plexiglas windows clean and
unmarred. The following procedure is recommended:
1. Flush with clean water and dislodge excess dirt, mud, etc., with your hand.
2. Wash with mild soap and water. Use a soft cloth or sponge, do not rub.
3. Remove oil, grease or sealing compounds with a soft cloth and kerosene.
4. After cleaning, apply a thin coat of hard polishing wax. Rub lightly with a
soft cloth.
5. A severe scratch or mar may be removed by using jeweler's rouge to rub
out the scratch, smoothing, and then applying wax.
BATTERY SERVICE
Access to the 12 volt battery is through the right rear baggage compartment
panel. The stainless steel box has a plastic drain tube which is normally closed
off with a clamp and which should be opened occasionally to drain off any
accumulation of liquid. The battery should be checked for proper fluid level, but
must not be filled above the baffle plates. A hydrometer check should be
performed to determine the percent of charge present in the battery.
If the battery is discharged, charge it before take-off as three volts are needed
to excite the alternator. Recharge starting at a 4 amp rate and finishing with a
2 amp rate. Quick charges are not recommended.
FUEL REQUIREMENTS
The minimum aviation grade fuel is 91/96 for the PA-28-180. Since the use of
lower grades can cause serious engine damage in a short period of time, the
engine warranty is invalidated by the use of lower octanes.
Whenever 91/96 is not available, the lowest lead 100 grade should be used. (See
Fuel Grade Comparison Chart, next page.) Refer to the latest issue of Lycoming
Service Instruction No. 1070 for additional information.
The continuous use, more than 25% of the operating time, of the higher leaded
fuels can result in increased engine deposits, both in the combustion chamber
