PIPER CHEROKEE WARRIOR SERVICE MANUAL
Some fuels have anti-icing additives preblended in the fuel at
the refinery, so no further blending should be performed.
Fuel additive can not be used as a substitute for preflight
draining of the fuel system drains.
The operation of the aircraft is approved with an anti-icing additive in the fuel. When an anti-icing
additive is used it must meet the specification MIL-I-27686, must be uniformly blended with the fuel while
refueling, must not exceed .15% by volume of the refueled quantity, and to ensure its effectiveness, should be
blended at not less than .10% by volume. One and one half liquid ounces per ten gallon of fuel would fall within
this range. A blender supplied by the additive manufacturer should be used. Except for the information
c o ntained in this section, the manufacturer's mixing or blending instructions should be carefully followed.

DRAINING FUEL VALVE AND STRAINER:
a. The fuel strainer, equipped with an easy drain valve is mounted on the lower left side of the fire
wall. The fuel strainer should be drained regularly to check for water or dirt accumulations. (Refer to Figure
2-9.)
b. The procedure for draining the right and left tanks and lines is to open the easy drain valve for a
few seconds with the fuel tank selector valve on one tank. Then change the fuel selector to the opposite tank
and repeat the process, allowing enough fuel to flow out to clear the fuel line as well as the fuel strainer.

DRAINING FUEL SYSTEM: The bulk of the fuel may be drained from the system by opening the
drain valve at the manifold assembly inboard of each fuel tank at the wing root. Push up on the arms of the
drain valve and turn counterclockwise to hold the drain in the open position. The remaining fuel in the system
may be drained through the filter bowl. Any individual tank may be drained by closing the selector valve and
then draining the desired tank.

ELECTRICAL SYSTEM.
2-59.
S E RVICING ELECTRICAL SYSTEM: Servicing the electrical system involves adding distilled
water to the battery to maintain correct electrolyte level, checking cable connections, and checking for any
spilled electrolyte that would lead to corrosion. (Refer to latest Piper Service Bulletin No. 631.) The security
of all electrical connections should be checked as well as the operation of all lights, general condition of the
alternator and starter. All electrical wires should be inspected for chafing and bare wires. For detailed infor-
mation on this system, refer to Section XI of this manual.
