Operating techniques
54 Lowering the attachment
Lowering the attachment
In technical incidents the attachment can be lowered to the
ground.
Lowering the attachment using accumula-
tor pressure
In case of standstill or engine defect.
If the electric power circuit is available and the accumulator is
pressurized, it is possible to lower the attachment with the
control elements.
1 Insert the ignition key into the ignition switch and turn it to "Tra-
vel Position" (position 2).
2 Shift lever (4) for safety interlock to position (B). The control le-
vers for working and travel hydraulics are unlocked (movement
possible).
3 The control elements (2) and (8) (see page 53) can be used to
lower the attachment.
NOTE! If lowering of the attachment is not possible because
the accumulator is depressurized, restart the engine to pres-
surize the accumulator.
Lowering the attachment in case of pro-
blems with the electric circuit
In case of standstill or engine defect and power failure.
1 Open the lateral hood.
2 Slacken screw (A) on the solenoid valve.
3 The control elements (2) and (8) can be used to lower the at-
tachment.
Relieving the residual pressure from the
accumulator
– Move the control elements (2) and (8) for boom, arm, bucket
and accessories to all directions.
WARNING!
Once the attachment has been lowered retighten the screw,
as otherwise the lowering protection is out of function.
WARNING!
