Hose lines with couplings
Only one type of hose is required for the various connection possibilities.
All connections are fi tted with nipples or sleeves to prevent mix-ups (can be coupled via
nipple and sleeve).
The hose lines are fi lled with hydraulic fl uid and bled of air in the as-delivered condition.
Proceed as follows to connect the hose ends:
1. The gold-coloured coupling nipple on the end of the hose must be connected fi rst.
Connection to the hydraulic cylinder is on the rod side, also called the annular chamber
side (= black coupling sleeve on blue connection block, see illustration).
2. The coupling sleeve of the hose is connected to the piston side of the cylinder (= silver-
coloured coupling nipple on cylinder with red connection block) (see illustration).
The opposite hose end is directed to the control table and connected to a valve with the
symbol "Lift/Lower".
The locking mechanism of the coupling sleeve must always be actuated. This prevents
inadvertent separation of the hose lines if their couplings are pulled over an edge during
their routing, for example.
