ADJUSTMENT OF THE THREADED ROD OF THE CONTROL VALVE
Front side trailer
Rear side trailer
All Cargo Floor systems have the threaded rod set and are fully tested. You therefore do not need to
adjust the threaded rod, but in certain circumstances (f.e. certain repairs) it may be necessary to check
or adjust the setting of the threaded rod. If switching spontaneously doesn’t go normally anymore, then
please make a good assessment first why this has happened.
Attention:
The pump and electrical installation must always be switched-off when working on the system; in
addition, the hoses and/or pipelines between the pump and the Cargo Floor should also be
disconnected.
If not the risk of entrapment arises!!!
Necessary tools:
2x spanner 17;
High viscosity oil;
Copper grease;
Steel brush.
Check that the threaded rod (1) is fastened securely to the switching valve, with pressing and pulling the
stroke is exactly 12 mm. [0.5”].
If not, then screw the threaded rod (1) as far as possible into the plunger and secure this with the contra
nut (2) (spanner size 17). Loosen nuts (3 and 4, spanner size 17) and move these about 3 cm [1.25”] in
the direction of the rear of the trailer.
Now switch the pump on while you are at a safe distance. The system will start to move and stops
automatically at the point where the command lip (7) no longer operates the switching valve, because
the spring (8) is no longer pushed. Switch off the pump immediately.
Now push the threaded rod (1) in the direction of the rear of the trailer until the spacer ring (9) touches
the control valve.
Tighten nuts (3 and 4) so far in the direction of the front side of the trailer that the spring is fully pushed
in, and secure them by tightening them against one another. Repeat this procedure for the other side
(nuts 5 and 6) by doing everything in opposite directions.
N.B. It is worthwhile spreading some copper grease on the threaded rod (1).
