Replacing hydraulic hoses
WARNING
Slipping hazard from leaked oil.
Bruising and bone fractures possible.
Clean up any leaked oil with a cloth or suitable binding
agents.
Wear safety shoes with non-slip soles.
CAUTION
Health hazard from contact with hydraulic oil.
Wear nitrile gloves and chemical-resistant protective
goggles during work that may include contact with
hydraulic oil.
The hydraulic hoses have to be replaced with new hoses of the same type if
any visible damage is found, but after seven years at the latest.
To replace a hydraulic hose, proceed as follows:
Switch off the unit.
To depressurize the unit, press the Stop button on the remote control
several times until the display of the pressure gage shows 0 bar (0 psi).
Disconnect the mains plug.
Release the screw connection of the couplings.
Remove one end of the hydraulic hose from the coupling on the unit.
Remove the other end of the hydraulic hose from the coupling on the tool.
Place one end of the new hydraulic hose on the coupling of the tool.
Place the other end of the new hydraulic hose on the coupling of the unit.
Tighten the screw connection of the coupling.
