9.3.2 Safety valves
The safety valves must be installed with the ring. These flaps are installed on the machine's
boom, rocker arm and blade cylinders to avoid the equipment falling to the ground if the hoses
break.
9.3.3 Overload box
• When the operator wishes to handle something, it is imperative that the overload box
switch is in the ON position to inform the operator of the tipping points depending on the load
being handled and the position of the equipment.
• An audible signal warns the operator that the load that he is handling is too heavy and could
well topple the vehicle.
• When the audible signal sounds, the operator must promptly put the load being handled
down on the ground because it could well topple the vehicle.

IMPORTANT
Activating the load indicator box does not stop the operator from making sure that the
load to be handled does not exceed the value indicated on the load table.
It is forbidden to handle the loads without turning on the overload box.
