The ambient temperature has been below -25
°C for a longer period.
The supply of grease to the LubeTronic
5Point
stops at an ambient
temperature of below -25 °C, because grease freezes at these tem-
peratures and cannot be dispensed.
When temperatures rise above -25 °C, the LubeTronic
5Point
auto-
matically resumes the grease supply, see section 3 "Intended use"
of this manual.
Lubricate the fifth wheel coupling plate manually.
The LubeTronic
5Point
was filled with grease
that has not been approved by JOST.
Replace the LubeTronic
5Point
unit.
3
The LubeTronic
5Point
does not lubri-
cate sufficiently, or at all.
The LubeTronic
5Point
connection to the vehicle
power supply is faulty or damaged.
Check the LubeTronic
5Point
connection to the vehicle power sup-
ply, see section 6.3.1 "Daimler/standard wiring diagram (4-pin con-
nector)" of this manual.
Check the connecting cable for damage and repair if necessary.
Check the routing of the connecting cable, see section 6.2 "Routing
the wiring harness" of this manual. The connecting cable must not
be crushed or stretched when the fifth wheel coupling is tilted (for-
wards or backwards). Replace damaged connecting cables.
No initial greasing was performed when the
LubeTronic
5Point
was commissioned, or after
cleaning the top of the fifth wheel coupling
plate.
Carry out initial greasing of the fifth wheel coupling as described in
section 6.4 "Initial greasing".
4
The surface of the fifth wheel coupling
is severely worn or rusty.
The LubeTronic
5Point
does not lubricate suffi-
ciently.
See fault 3 in this table.
5
The function lamp does not light up
when the ignition is switched on.
The LubeTronic
5Point
connection to the vehicle
power supply is faulty or damaged.
See fault 3 in this table.
