32 41 ... Notes on hydraulic line with quick-release coupling





1. Quick-release coupling with ID marking

Removing:
Push quick-release coupling (1) against pipe (4) (thereby relieving strain on spring (2)).
Press plastic ring (3) into quick-release coupling (1) and remove coupling (1).
Installing:
Markings (K) on coupling (1) and pipe (4) must be flush.
Push quick-release coupling (1) onto pipe (4) until a "click" can clearly be heard.
To check that quick-release coupling (1) has been installed correctly, pull it back forcefully.





2. Quick-release coupling with indication pins
Removing:
Press plastic ring (2) into quick-release coupling (1) and remove coupling (1).
Installing:
Push quick-release coupling (1) onto connector (3) until both indication pins (4) can be seen and felt to point outwards at outside diameter of housing.
To check that quick-release coupling (1) has been correctly fitted, feel indication pins (4) at outside diameter of housing. When correctly seated, indication pins (4) cannot be pressed into housing.

Caution: Coupling is not correctly engaged if both indication pins (4) fail to protrude from housing. Leakage is thus
