system is drained and purged, and the source of contamination is
determined and corrected.
If sampling reveals the airplane has been serviced with an improper
fuel grade, do not fly the airplane until the fuel system is drained and
refueled with an approved fuel grade.
To help reduce the occurrence of contaminated fuel coming from the
supplier or fixed based operator, pilots should assure that the fuel
supply has been checked for contamination and that the fuel is
properly filtered. Also, between flights, the fuel tanks should be kept as
full as operational conditions permit to reduce condensation on the
inside of fuel tanks.
Draining Fuel System
The bulk of the fuel may be drained from the wing fuel tanks by the use
of a siphon hose placed in the cell or tank through the filler neck. The
remainder of the fuel may be drained by opening the drain valves. Use
the same precautions as when refueling airplane. Refer to the SR20
Maintenance Manual for specific procedures.

Battery Service
Access to the 24 volt battery is gained by removing the upper cowl. It
is mounted to the forward right side of the firewall. The battery vent is
connected to an acid resistant plastic tube that vents gases and
electrolyte overflow overboard.
The battery fluid level must not be brought above the baffle plates.
Until experience indicates a longer interval is justified, the battery
should be checked every 30 days to determine that the fluid level is
proper and the connections are tight and free of corrosion. Do not fill
the battery with acid use distilled water only.
If the battery is not properly charged, recharge it starting with a rate of
four amperes and finishing with a rate of two amperes in accordance
with Airplane Maintenance Manual (AMM) procedures. The battery
should be removed from the airplane for charging, and quick charges
are not recommended.
The external power receptacle is located on the left side of the
fuselage just aft of the firewall. Refer to the Airplane Maintenance
Manual (AMM) for battery servicing procedures.

Cleaning and Care
Cleaning Exterior Surfaces
• Note •
Prior to cleaning, place the airplane in a shaded area to allow
the surfaces to cool.
The airplane should be washed with a mild soap and water. Harsh
abrasives or alkaline soaps or detergents could make scratches on
painted or plastic surfaces or could cause corrosion of metal. Cover
static ports and other areas where cleaning solution could cause
damage. Be sure to remove the static port covers before flight. To
wash the airplane, use the following procedure:
1. Flush away loose dirt with water.
2. Apply cleaning solution with a soft cloth, a sponge or a soft bristle
brush.
3. To remove exhaust stains, allow the solution to remain on the
surface longer.
4. To remove stubborn oil and grease, use a cloth dampened with
naphtha.
5. Rinse all surfaces thoroughly.
Any good silicone free automotive wax may be used to preserve
painted surfaces. Soft cleaning cloths or a chamois should be used to
prevent scratches when cleaning or polishing. A heavier coating of
wax on the leading surfaces will reduce the abrasion problems in these
areas.
