ETECTING ANOMALIES
16.1 phenomena that do not constitute faults
The following phenomena are not faults :
•
Bucket shaking
When the boom is raised immediately after the
arm is extended while the bucket is pulled back,
the bucket may shake. This is not a fault.
A
•
Discontinuous movement of the arm
When you dig the ground with the arm, the arm
may slow down temporarily in an almost vertical
position. This is not a fault and occurs especially
when the motor speed is low.
A = Slowdown is noticeable on this range.
•
Shift in the position of the upper chassis
When you turn the machine suddenly, as in turning or pivoting, the upper chassis may be slightly
offset.
•
Thermal shock for the side movement motor
If, during cold weather, the hydraulic oil temperature rises to over 60°C in relation to the exterior
temperature, during an unloading operation without movement after the engine starts the machine
may not pivot because of a thermal shock. This is not a fault.
•
The rotation cylinder extends during excavation
The rotation cylinder may extend in certain situations or excavation positions. This is not a fault.
•
Delayed reaction to the response to change of speed
At slow engine rate, a reaction delay may occur when you reduce the speed. This phenomenon is
not a breakdown.
