Malfunction
Possible Cause
Actions to be undertaken
The motor does not
run
1.
Mechanical transmission block.
2.
The motor does not generate
enough
torque
because
the
operating pressare is too low.
3.
The electric motor does not supply
enough power.
4.
Piloting pressure is too low (dual &
variable displacement motors only).
5.
Piloting system failure (dual &
variable displacement motors only).
1.
Check system pressure. In case the
system pressare exceeds the relief
valve pressare set, remove the load
from the transmission.
2.
Check the system pressure level
and, if necessary, correct the
pressure limiting valve set value.
3.
Check the hydraulic schematic.
4.
Increase the piloting pressare up to
