WARNING
Before fitting a new high-pressure pipe, lightly
lubricate the nut threads with the oil from the
applicator provided in the new parts kit.
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.
