Maintenance Instructions

8
This chapter describes the performance of maintenance work. In addition, the preservation of engines as
well as winter and tropical operation is covered.
Caution:
Disconnect spark plug connectors before performing any work on the engine.
Caution:
When starting the engine, the propeller area must be clear. Secure the aircraft from
rolling. No persons may be present in the propeller area.
Note:
Vacuum pump equipped aircraft engines must never be turned opposite to the engine rotation
because the vacuum pump might be damaged.
Check with your airworthiness inspector if inspection is mandatory before starting work.
It is recommended to mark the position of parts to be removed before commencing disassembly
work in order to facilitate assembly later on.
This is only applicable to parts which might be installed in different positions. During assembly,
pay attention to markings provided by the manufacturer.
The spark plug connectors are marked with the cylinder numbers.
It is not important whether they are attached to the out- or inboard spark plugs.
