6	Compress compensating element, to do this depress the roller-type cam follower (1) using a suitable drift (01)	 Do not use a steel tool. The surface will be damaged otherwise.
		 The compensating element should not be pressed together with the normal force of the hand but only very slowly when applying a strong pressure.
		 Check the pressure oil supply to the cylinder head if more than one compensating element is defective.
