The engine manufacturer recommends ashless dis-
persant oils. However, a straight mineral oil should be
used for the first oil change period of 20 to 30 hours or
until oil consumption has stabilized in order to promote
faster ring seating and oil control. Oils must meet Con-
tinental Motors Corporation Specification MHS-248. Refer
to APPROVED ENGINE OILS.
BATIERY
The battery is accessible by opening the right engine
cowling. Check the electrolyte level after each 25 hours of
operation and add distilled water as necessary. Do not
overfill the battery.
Excessive water consumption may be an indication that
the voltage regulator requires resetting. The specific
gr13vity of the electrolyte should be checked periodically
and maintained within the limits placarded on the battery.
The battery box is vented overboard to dispose of
electrolyte and hydrogen gas fumes discharged during the
normal charging operation. To ensure disposal of these
fumes the vent tube should be checked frequently for
obstructions and should be kept open.
