If your vehicle is equipped
with 2 different types of coup-
lings, you must use only one
type at the same time.
When the couplings are
mounting/demounting, the
parking brake of the truck and
trailer must be engaged.
If the brake parameters are
modified, your vehicle's brake
calculation might be non-sui-
table for regulations. Only aut-
horized services must service
to the EBS modulator.
Only authorized services and
personnel should make servi-
ce operations for the brake
system.
There might be test points on the chassis
or above the air couplings. When you re-
move the test points rubber protection
parts and push the points you can check
the air pressure on the brake lines.
One of the test points is the
service line. As long as there
is no brake signal from the
truck side, this line will be
empty, there will be no air at
the test point. The other test
point is the brake air tubes li-
ne. From this test point, it can
be checked whether there is
air in the vehicle.

Palm coupling with a test point
3.1.1.1. Mounting of Standard (Palm)
Couplings
Couplings
• Slightly slide plastic covers to the
up-per side. Slide plastic covers to
upper side.
• Be sure that sealing surfaces are
clean and durable. If necessary,
clean/change the air coupling.
• The coupling which comes from the
truck should be pushed slightly from
the upper side to the lower side and
connect the coupling. Be sure that
couplings are matched correctly.
• First mount service line yellow (1).
• Mount supply line red (2).
3.1.1.2. Demounting of Standart
(Palm) Couplings
• The coupling which comes from the
truck should be pushed slightly from
the lower side to the upper side and
demount the coupling.
