Replacing the seals and assembling the assembly
1. Lightly grease the O-rings (e.g. with Syntheso Glep 1).
2. Replace the seals (O-rings) if necessary.
3. If you have not already done so, wrap Teflon tape around the thread of the retraction
pipe.
 This protects the seals from damage when inserting the retraction pipe.
4. Grease the retraction pipe.
5. Reassemble the assembly.
6. Make sure that the locking ring above the bayonet nut is correctly seated.
7. Remove the Teflon tape once you have inserted the retraction pipe.
