Use Of Hydraulic Hammer - Case WX145 Operator's Manual

USE OF HYDRAULIC HAMMER

BEFORE BEGINNING WORK
Check that the hydraulic hammer is safely locked on
the working equipment and that the hydraulic lines
are connected in the right way.
SWITCHING ON THE HYDRAULIC HAMMER
Select the "Hydraulic hammer" function by depress-
ing switch face without symbol (1).
The electronic control unit switches into power level
4, 5, 6 or 7, depending on which level was active
before engine shut off.
Pedal (2), if installed on the machine, is now control-
ling the "hydraulic hammer".
The selection menu (A) for 4 hammer types is dis-
played for 10 seconds. Another hammer 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.
After returning to the main screen, the hammer sym-
bol (B) is displayed.
The display shows the hammer symbol and the
working mode selected.
The number of the selected hammer is shown
above the symbol.
If the machine is to work alternately with the hydrau-
lic hammer and with other hydraulic attachments
(e.g. hydraulic shears), an electrically operated
shuttle valve automatically connects the return-flow
line of the hydraulic hammer with the hydraulic res-
ervoir.
IMPORTANT: when several hydraulic attachments
are activated at the same time, the first switch set-
ting has priority.
