1) Saw or cut the hose in the right length.
a) Check the hose diameter.
Tolerance outside: A
Tolerance inside: B
2) Clean the ends for metal filings.
3) Screw on the covering to the hose
- note that the covering has left-hand thread.
4) Screw the covering as far as it will go and then back, so
the hose is allowed to expand when the insert is screwed
in (see drawing).
5) Lubricate the end of the insert with a detergent, and
install the insert by means of an Allen key.
6) Do not allow the hose to turn around while the insert
is being screwed in - use special tool from Nortec and
screw in the insert in one long movement.
7) Insert has to be screwed completely home, so it is locked.
8) Check with a C Allen key that there is a free passage
through the insert. The key must be led completely
through to the bottom without any resistance.
