3.9.4
Operating the boom
When the warning system is activated due to overload, the boom must be lowered until the load is on the ground
and the load is lightened. To prevent bodily injuries, in the event of overload, no other functions (e.g. turning the
superstructure) must be executed.
•
Pull the right control lever back to raise the boom (diagram: arrow
down).
•
Push the right control lever forward to lower the boom (diagram:
arrow up).
NOTE
The boom has a hydraulic cylinder with damping that prevent the bucket contents from falling out of the bucket. If
the operating temperature of the hydraulic oil has not yet been reached, the damping effect only takes place after
a deceleration of about 3 to 5 seconds. This is due to the viscosity of the hydraulic oil and is not a malfunction.
CAUTION
When lowering the boom, make sure the boom or the teeth of the bucket
do not bump against the dozer blade. The boom moves as shown on the
diagram.

arrow up).
•
Pull the left control lever back to retract the arm (diagram: arrow
down).
