To check that the pressure hose is fitted correctly, pull it slightly against the insertion direction. If it is fitted correctly, it cannot be pulled out or only pulls out when great force is applied.

The following points must be observed when choosing the repair point:

The repair point must lie in an area protected from water spray
The push-on connector must be fastened with tie-wraps to the structure or a cable guide
Straight pipe sections should be chosen for the repair
Position the pressure hose back in its original fastenings
Insert the ends of the pressure hoses firmly into the push-on connector.
