4 Accumulator
The accumulator stores hydraulic oil so that much of
the hydraulic capacity is available during operation of
hydraulic functions.
5 Main valve
The main valve shuts off the accumulator from the

This valve must be closed if the installation is not in
use. The valve can be accessed via an opening in
the protective cover.
The power unit cannot be switched on if the valve is
closed.
6 Oil depressurising
valve
This valve is normally closed. If the hydraulic
installation needs to be depressurised to implement
work, open this valve slowly. The plug must be out of
the socket and valve 5 must be open in order to also
allow the oil to flow out of the accumulator.

What to do
Action
Result
1.
Tip the nose wheel
downwards.
Ensure that the crush is resting on the
nose wheel.
2.
Connect the crush.
See 4.2,5.1
3.
Lower the adjusting
feet
Lower the 2 front adjusting feet
(Figure 4:3) by pushing them down
with the foot and lock them at the
desired height with the chain.
If the lift option is fitted, then first
remove the folding gates (Figure 4:2)
from the crush and allow the crush to
rise under hydraulic pressure.
4.
Remove the locking
pin from the drawbar.
Rotate the locking pin upwards
(Figure 4:4) and remove it.
5.
Open the front gate.
Operate the valve to open the front
gate.
6.
Tip the crush back.
Tip the crush to the rear so that the
drawbar is clear of the ground. With
the rear gate raised the crush will
remain in that position. Check that the
folding gates are still secured with the
front support feet ropes.
This is not necessary with the optional
lift.
7.
Free the drawbar and
the brake cables.
Rotate the locking knob (Figure 4:6)
and unlock the clamp situated in the
middle of the drawbar, then slide the
nose wheel of the crush off until the
drawbar comes free from the crush.
The brake cables are now free of
tension and can easily be unhooked
at the wheel side.
Once the brake cables are loose they
can be placed in the tube provided in
the middle of the drawbar. Keep
fingers clear of this tube to avoid
danger of trapping.
8.
Tip the crush
forwards.
Lift the rear of the crush so that it tips
forwards. The drawbar now rests on
its nose wheel and the ball joint
connection in the box.
Where the lift option has been
selected you should now remove the
mudguards (see point 10), tilt the
wheels (see point 13) and then allow
the crush to sink hydraulically using
the lift.
Disconnect the drawbar ball
mounting.
9.
Remove the drawbar.
Remove the drawbar from the crush
and store it out of the way. The shaft
will be held upright by the elastic cord
attached to the ball mounting.
10.
Remove the
mudguards
Loosen the locking elements and lift
the mudguard out of the adapter.

Lower the 2 rear adjusting feet (Figure
4:1) by pushing them down with the
foot and lock them at the desired
height with the chain.
13.
Tip the axle.
Lift the axle cylinder locking
mechanism.
Operate the valve until the wheels are
folded up.
14.
Install the side gates.
Withdraw the side gates (Figure 4:2)
from the crush and place them in the
desired position.
4.2. Connect the machine.
CAUTION
Check that the voltage specified on the machine plate matches the mains
supply.
The machine must always be connected to an earthed socket to avoid the
risk of fire or electric shocks (the earth connection is coded green/yellow).
The electrical installation including the sockets must be connected in
accordance with local regulations.
The power cable must always be free and nothing must be placed on top of
it.
Replace the power cable immediately if it is damaged.
4.3. Preparing for transportation.
CAUTION
