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

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