4.3 Outlet connection
4.3.1 Connection coaxial line / outlet port
!
The coaxial line may be only con-
nected by authorized and trained
specialists.
!
The coaxial line has first to be
connected to the outlet port of the
VTEC, and then to the nozzle.
!
It is recommended to identify an
outlet in accordance with the noz-
zle it supplies, e.g. with tubes of different
colors, with identification rings or
others.
The coaxial line (from 1 to 5 m*) is connect-
ed to the VTEC outlet port by means of
quick-release connectors.
*) For greater line length, please contact the SKF service center.
D A N G E R !
Before connecting the pump to
the compressed air feed ensure that the
main air valve is closed.

Every outlet port has two quick-release con-
nectors (
† fig. 4
).
The lower connector holds the capillary
tube of the line (lubricant). The upper con-
nector (orange collar) holds the outer tube of
the coaxial line (air).
