6. CLEANING

6.1 CLEANING, INJECTOR

}

The injector body (nozzle) must

never be cleaned with copper or

steel wire brush. When cleaning the

exterior of the injector nozzle, do not

pass the brush over the injector

nozzles. If this happens, the nozzle

must be replaced.

Injector nozzles
The use of steel or copper brushes can cause

deformation of the injector nozzles with the result

that the fuel is not injected in the corrrect way and

the amount of fuel injected is affected.

Such deformation cannot be detected by carrying

out the normal injector test.

}

The injector nozzles must not be

cleaned (with a needle).

Nozzle
Before cleaning the nozzle, cover the injector

nozzles and only clean the nozzle with the brass

hand brush in the injector cleaning set

(DAF no. 1329371).
