6.6.3 INSTALLING AND REMOVING THE
DEMOLITION HAMMER
6.6.3.1 INSTALLING THE HAMMER
The machine must be parked on a level surface, with the
q
front equipment resting on the ground.
For the installation, the hammer must be positioned
q
horizontally, with the bit directed towards the machine.
When the coupling pins are removed or installed, chips
q
may come off; always use gloves, goggles and helmet.
The change of the equipment must be carried out by two
q
operators, who must decide together the words and
signals to be used during work.
Avoid using your fingers to align the holes, since they may
q
be injured or even cut off.
Before carrying out any operation on the hydraulic circuit,
q
eliminate the residual pressure from the equipment circuits
by moving the controls more than once and from the tank
by slowly loosening the filler cap.
If any oil has been spilled, wipe it up immediately, in order
q
to prevent the surface from getting slippery.
For the installation of the demolition hammer it is necessary to
connect the mechanical constraints of the backhoe bucket as
described in "3.13.4.1 CHANGING THE BACKHOE BUCKET"
and to carry out the hydraulic connections using the pipes
provided.
After connecting the mechanical constraints, carry out the
hydraulic connections by proceeding as follows:
1 - Stop the engine and move the hydraulic controls in all
directions, in order to completely release the residual
pressure present in the circuits of the machine.
2 - Press the hammer control pedal to release the pressure
present in the hammer delivery pipe.
IMPORTANT
If the machine is equipped with backhoe servo controls, to
q
eliminate the residual pressure proceed as follows:
1 - With the engine at rest, turn the ignition key to position
« ».
2 - Press the servo control locking button and make sure
that the LED is off (release position) (see "3.3.2 pos. 12
- SERVO CONTROL LOCKING BUTTON").
3 - Shift the backhoe control levers more than once and
press the hammer control pedal.
4 - Turn the ignition key to position « ».
