Annually check existence on hoses of cracks, hardenings, swellings and other damages. Hoses are recommended to be changed through 80000 km of a run.

For replacement of a hose release a collar and remove a hose. If necessary make an incision.

At installation dress a collar so that it settled down in 6 mm from edge of a branch pipe.

The removed intact hoses are recommended to be carried with themselves as they can be useful for replacement of incidentally failed hose.
