• When the coupling is closed, there must be approx.
10 mm clearance in the handle before the indicator/
locking pin moves outwards.
Safety check
Carry out the safety check once a week. If the check
shows that any of the wear limits have been exceeded
or that the coupling´s function is reduced, rectifi cation
must be carried out immediately.
Before any work or service is carried out on the coupling
all air supply to the coupling must be cut off. Cut off
the air supply by turning the control box’ red handle a
quarter turn anti-clockwise to OFF.
Function check
• Check that the coupling bolt can be raised easily
and that the handle and coupling bolt remain in the up
position.
• Open and close the coupling and check that it cor-
responds as per the pictures below. If an inductive
sensor is used, item (d) must be complied with.
ALWAYS check that the coupling is closed and secure
before driving. All criteria for closed coupling must be
fulfi lled before you start driving.
Warning!
Never put your fi ngers in the coup-
ling mouth because of the danger
of them being crushed.
If the coupling has been damaged
as a result of jack-knifi ng, driving
into a ditch, or being hit from be-
hind, you must stop and replace
the coupling.
