Position the clamp collars so that the retaining collars are
located directly above the security flange of the hose con-
nector.
Place the nuts provided in the pockets in the clamp collar.
Screw the two clamp collars together. Tighten the screws
uniformly and alternating until a maximum gap height of
15 mm remains at both sides. The gap must run in parallel,
and must be absolutely identical at both sides.
You can carefully clamp the collars in a vice to make it easi-
er to screw them together.
The specified gap height can be used for the "HANSA Flex
TE 308 B (3TE)" hose.
When using other hoses, the gap height can deviate with
reference to safe and reliable mounting and installation.
