9 - ACCESSORIES
To handle suspended loads proceed as described below:
• Evaluate (if not known) the mass of the object to be
handled.
• Press the ON side of the overload switch
(1) to acti-
vate the overload warning alarm. The overload warning
alarm is intended to avoid lifting of excessive loads.
NOTICE: if an overload condition is detected during the
handling of the load, When the machine is overloaded,
a buzzer sounds and the red warning lamp in the instru-
ment cluster is ON. Place the load onto the ground and
check the load conditions making reference to the chart
located inside the cab/canopy.
• Secure the load with the load handling eye (optional)
(2) located on the bucket linkage rod, using slinging de-
vices and chains adequate for the load to be lifted. In
order to limit the swinging of the load, avoid slinging it
with cables and/or chains too long.
• Extend the bucket cylinder to end stroke.
• Check the surrounding working area and make sure
that the path to be travelled with the load is free from
obstacles.
• Lift slowly the load, avoiding sharp movements which
could cause swinging of the load. Keep the load near
the machine, to improve the stability and operate,
preferably, along its longitudinal axis, rather than cross-
ways. Lift the load from the ground the minimum height
required.
• Position and place the load where desired, making sure
that it is resting on a solid base appropriate for its mass.
• Remove the chains.

Safety valves
The safety valves are intended to prevent the front equip-
ment from dropping down in the event of a breakage or
burst of a hose in the hydraulic lines of boom and arm.
The safety valves keep the front equipment in the posi-
tion at the time of breakage, and thus allow the operator
to slowly lower the attachment to the ground using the left
and right control levers.
Moreover, the safety valves allow an operator to keep the
front equipment in the selected operating position, reduc-
ing the leakages that occur in the neutral position of the
boom spool and the arm spool in the main control valve.
NOTICE: prior to starting any handling of suspended
loads check that the valves do not show clear evidence
of damages or abnormal noises. In the event abnormal
conditions are found, contact the CASE CONSTRUC-
TION. dealer.
NOTICE: the pressure setting of the safety valves must
be checked every 6 months. Consult the CASE CON-
STRUCTION dealer.
