CAUTION:

Pay close attention to the following points when installing fuel injectors.

Blow out injector recesses, clean again with a non-woven cloth and then cover over. Fiber residues from woven cloths ARE NOT permissible.
Carefully carry out a visual inspection of the sealing surfaces of the injector recesses.
The length of the round brush can be adjusted and should be approximately 3 mm for cleaning the seal seat. Optimal cleaning is achieved only if a brush with a flat surface is used. If necessary the surface of the brush can be ground flat on a grinding stone.
ALWAYS replace the seals which seal off the injectors at the cylinder head to the combustion chamber. It is important that no grease gets onto the seal. Any impurities on the seal, on the sealing surfaces at the injector and cylinder head as a result of combustion residue or similar are absolutely not permissible.
The nuts attaching the injectors must always be replaced.
The tip of the injector nozzle MUST NOT be cleaned with a wire brush. Use a non-woven cloth.
Clean entire injector with a non-woven cloth.
Fiber residues from a woven cloths are not permissible.
