Fig. 5-2 - 1 Operation of the splitting device
z
Before commissioning the splitting device, please heed the safety instruc-
tions in chapter 2 of this product manual!
The splitter is operated with the operating lever at the upper end (head side) of the
device. Depending on the position of the lever, you can differentiate between three
different operating states:
R
Wedge back:
The wedge is retracted. As soon as the wedge has been completely retracted,
the pressure limitation valve built into the Darda aggregate relieves the pressure
cylinder (noticeable in the clearly audible bang from the aggregate).
N
Zero position:
The wedge does not move. The hydraulic system is not under pressure (re-
lieved).
F
Wedge forward:
The wedge is extended and presses the two pressure pieces apart. As soon as
the wedge has been completely extended, the pressure limitation valve built into
the Darda aggregate relieves the pressure cylinder (noticeable in the clearly
audible bang from the aggregate).
Make sure (due to the danger of the hydraulic oil overheating) that the oper-
ating lever is in the zero position on at least one splitter in the case of long
interruptions with a running hydraulic aggregate!
