In case of operation abnormalities and/or to remedy any operation faults, take 

advantage of the instructions included in this chapter to trace the causes.

CAUTION

Only skilled and qualified technicians may provide technical support. For 

any other kind of work or instruction, please feel free to contact the WESTCAR 

Customer Support Service. You will benefit from a prompt intervention by very 

experienced staff.

Below you can find summarized data tables about the faults, which may occur 

during operation and the first maintenance work to be planned.

INCONVENIENCES AND REMEDIES

FAULT

THE HYDROMECHANIC COUPLING OVERHEATS OR THE EXPANDABLE 

PLUG IS RELEASED TOO OFTEN

Possibly causes to be 

checked.

1   Cooling is not enough due to missing or unsuitable air intake on the 

carter or on the guard

2   The carter is equipped with a cooling fan, but it is out of order and it 

turns in opposite direction

3  The ambient temperature is still high, or there are sources of heat next 

to the coupling

4  The driven machine is operating with excessive overload
5  Not enough transmission oil in the coupling
6  Oil is leaking from the hydromechanic coupling
7  Too frequent or too long start-up cycles
8  The hydromechanic coupling is undersized

FAULT

THE DRIVEN MACHINE CANNOT REACH FULL SPEED

Possibly causes

to be checked

1  Not enough transmission oil in the coupling
2   Oil leaks from the hydromechanic coupling
3  The driven machine is operating with excessive overload
4  The motor installed power is not enough
5  Too low ambient temperature
6  Too thick transmission oil in the coupling
7  The motor input speed is not sufficient
8  The hydromechanic coupling is undersized
