3. Swivel sealing rings, as shown at previous section "swivel & sealing
rings replacement".
4. Unscrew the shaft (4) (fig. 13). For doing this, it is needed to do
counterforce by introducing an Allen key 7mm between faces (1)
(fig. 8) inside the brass hexagon (2) (fig. 8), through the Tensor
piece (3) (fig. 8). Avoid to transmit stress to other hose reel
components.
5. Once the shaft has been taken apart, you will be able to reach the
inner sealing ring (5) (fig. 13). Replace it if necessary. This sealing
ring is used in all the hose reels models, located inside the inner
rotating part (6) (fig. 13).

It is no necessary to disassemble the casing for easily replace the swivel.
Follow the next steps to do it:
1. Make sure the hose stopper is in contact with the rollers outlet.
2. Take apart the circlip (1) (fig. 12) and remove the swivel (2) (fig. 12).
3. Replace the sealing rings (3) (fig. 12). For the medium & high
pressure hose reels, the sealing rings are located on the swivel. For
low pressure hose reels, the sealing rings are located on the shaft. If
you also need to replace the swivel, disconnect the inlet hose from
it and connect the hose again to the new swivel.
4. Apply a bit of grease to the swivel and the shaft (4) (fig. 12) before
introducing the swivel carefully through the shaft.
5. Place again the circlip on the shaft.
6. Introduce carefully the shaft inside the inner rotating part (6) (fig. 13),
through the inner sealing ring (5) (fig. 13), be careful not to damage
it with the shaft thread. It is recommended to clean the threads and
apply a medium strength threadlocker in this threaded coupling. For
tighten the shaft, again use the Allen key to make counterforce,
avoiding the stress to transmit to other hose reel components.
7. Apply a bit of grease to the swivel and to the shaft, and introduce
the swivel through the shaft carefully.
8. Finally, place again the circlip (1) (fig. 13) on the shaft, and take
apart the Allen key (1) (fig. 8).
