MAINTENANCE MANUAL STEMME S12
5.4.23 OPTIONAL EQUIPMENT
WING FOLDING DEVICE
The wing folding device itself is maintenance-free. The sliding surfaces should not be lubricated
in order to avoid sticking of dirt, which could result in the formation of marks on the swivel arm
and thus to wear. From time to time, the swivel arm should be cleaned by means of a soft cloth.
