Lubricate areas marked in yellow:
Side of handle (1), hinge joints and lever guides (5).
Generously lubricate the top side (2) and completely fill the lubricating groove (except W version – the top plate liners do not have to
be greased; JOST top plate liners are resistant to lubricating greases).
Lubricate lock jaw (3) and locking bar (4) with the fifth wheel coupling closed.
With the standard version (not the low-maintenance version), the centre area around the wearing ring (6) must be completely filled
with grease (see marked area).
Grease specification: We recommend JOST high-performance lubricant (article no. SKE 013 440 000).
