ExTe TU - Installation; Connecting Compressed Air

11
Connecting compressed air
TU has a valve kit. The vehicle's pneumatic system is connected to the valve and is used to shut o the air
supply to ExTe TU before the tensioner is put into the disengaging position. The installation and placing of
the valve kit can vary and can be adapted to the user's requirements. The main valve kit, item no. 802301
can be used to regulate the air supply to several TU tensioners at the same time.
m Note!
Plan the placing of the valve kit and air hoses
carefully to avoid them getting too close to other
moving parts, such as the disengaging lever.
Secure hoses in an appropriate way. Valves
should be easily accessible.
