USE OF HYDRAULIC SHEARS

BEFORE BEGINNING WORK
Check that the hydraulic shears are safely locked on
the working equipment and that the hydraulic lines
are connected in the right way.
SWITCHING ON THE HYDRAULIC SHEARS
Preselect "Hydraulic shears" with rocker switch (1).
Depress the blank face of switch, switch backlight-
ing is on.
Once the function is set, the display shows for 10
seconds menu (A) for the selection of 4 different
shears types. The shears can now be selected, e.g.
3 instead of 2 and/or the pertaining pressure and
volume flow settings can be changed. To quit the
menu before the 10-second interval has elapsed,
depress one of the arrow buttons used for setting
the machine power levels.
If the machine is to work alternately with the hydrau-
lic shears and with the hydraulic hammer, an electri-
cally operated shuttle valve automatically connects
the return-flow line of the hydraulic shears with the
hydraulic reservoir.
The electronic control unit switches into power level
1 - 7, depending on which level was active before
engine shut off.

To close the shears:
press pedal forward (5).
To open the shears:
press pedal backward (5).
Push-button (4) can be used to switch pedal (5) dur-
ing the work temporarily over to control the adjusting
cylinder. The buzzer sounds a warning as long as
the push-button is kept depressed.
