4.2.8 External power
If the battery is dead, an external power source can be used when star
ting the engine.
If the glider has a battery mounted in the engine compartment, the
engine compartment doors must be open to reach the batterry ter
minals. Disconnect or loosen the engine brake in order to be able to
crank the engine with the doors open.
Use a 12-volt auxiliary battery and connect the terminals with the bat
tery cables. Be careful to connect positive terminal to positive and nega
tive to negative. Start the engine normally and disconnect the auxiliary
battery when the engine is running. Stop the engine when it is warm
enough to start with its own battery and connect the engine brake.
When the glider has the battery mounted below the instrument panel,
it is also equipped with wires for a jumper cable connection. An auxiliary
battery can then be connected to the wires and the engine started as
described above.
NOTE
The engine must not be run without a battery because the alternator
may then produce high voltage peaks.
4.2.9 Preserving the engine
When the engine is stored for longer periods without use (over 2
months) the engine must be preserved as follows:
— warm up the engine
— spray 20 ccm (0.8 oz) special preserving oil (Shell: Ensis, BP: Protec
tive Oil, Mobilarma 524 or equal) to carburettors and stop the engine
— turn the engine by hand until the compression feels higher
— cover carburettors and exhaust pipe
— drain the fuel system
Especially when the engine is stored during the winter period, the condi
tions can be rather corrosive without preserving. When the engine use
per year is little, good care lengthens the life of the engine.
