ETECTING ANOMALIES
17.1
P
henomena 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.
• 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 mo-
tor 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 exte-
rior 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 phenomen-
on is not a breakdown.
