WARNING
Before fitting a new high pressure pipe, lightly
lubricate the nut threads with oil from the applica-
tor provided with the new part.
Be careful not to allow oil into the high pressure
pipe.
Do not lubricate high pressure pipes supplied
without an applicator, as these high pressure
pipes are self-lubricating.
WARNING
Do not remove the blanking plugs from each
component until the last moment.
