Commissioning

Before every use, the hose reel must always be checked for visible damage to the hose reel
and accessories, in particular the hose equipment and hose connections.
Dust deposits and caked layers must be removed, especially from the rotating parts such as
the inside and outside of the drum, taking care not to stir up the dust. Test the operation of
the rotating parts for example the swivel and the hose outlet.
Especially at temperatures below 0 °C, if water is used as the medium, ensure that remains
of the medium do not freeze and cause the hose reel to stop functioning. The remains of the
medium must be emptied from the hose.
