Flexible propeller shaft coupling UNIFLEX
ENGLISH
To prevent slipping between the clamping-joint and the pro-
peller shaft, they must be free of grease and dirt (*).
The numbers indicate the
sequence in which the bolts
have to be tightened.
If necessary, tighten the bolts
again.
Take care that the rub-
ber parts are not affect-
ed by solvents.
