7.4.3 Lubrication of the spiral thread spindle (not ND models)
Generator Failure
The spiral thread spindle must be lubricated carefully and regularly. Please only use a temperature independence
lubricant (up to 100°C) witch is also equipped with „emergency run qualities“. Spread also lubricant to the end of the
nuts.
It is possible that the spindle could clamp if the spindle is not enough lubricated. Then the generator can be switched
off by over- or under voltage.
All screws at the actuator and the spindle must be ensured „solvable“ with a screw safety grease.

7.4.4 Effects of a overload to the actuator (not ND models)
Fig. 7.4.3-1: Actuator
If the generator is overloaded the voltage falls on account of a not adequate motor power under the nominal value.
The actuator stays at the upper keystroke and tries to rev up the diesel engine. An internal regulation limits the current
to the actuator, nevertheless a longer overload can damage the winding of the actuator. (short of the winding).
The motor gets not strictly inoperative but it can happen that the cranking torque of the actuator is getting weak. This
has the consequence that the rev spindle can not be turned to all positions faultless. Therefore the voltage of the
generator is regulated not good or sometimes not at all.
If you notice that the spindle of the actuator doesn't run faultless, first check if the aggregate was overloaded for a
short time and if thereby the winding of the actuator was damaged. Then the actuator has to be changed.
Check the electrical fuse (miniature slow-to-blow fuse
1,6A) on the control printed circuit board if the actuator
will not turn at all.
