6.2 Start-up
Before start-up and following repairs, the hose assemblies of the hose reel must be
deaerated:
- Connect the hose reel to the hydraulic pump (see chapter “Connecting the equipment”).
- Switch on the hydraulic unit and pressurize the supply hoses for some time.
- Switch the hydraulic unit to depressurized circulation or switch it. If necessary, you have
to top-up hydraulic fl uid.
CAUTION!
The working equipment has to be disconnected!
REMARK when using mono-couplings:
We recommend coupling the coupling halves in a pressureless state, when
working in areas with low ambient temperature otherwise decoupling could
need very high expenditure of force.
After the deaeration the working equipment can be reconnected to the hose reel.
The parking brake prevents the extension hose pairs from unrolling during transport!
In order to release the parking brake, turn the knob A anti-clockwise until there is a distance
of approx. 5 mm / 0.2 in. between the brake shaft B and the hose drums C.
In order to activate the parking brake, turn the knob A clockwise until brake shaft B is fi nger-
tight with the hose drums C.
