TrackDrive (TD) Series
Operating & Safety Instructions
9. Control modes;
The standard EU control circuit will permit independent operation of either control position, working
through a series Emergency Stop control circuit. In some countries (e.g France and Australia) the
alternate control interlock permits the cage system to be isolated by the ground control key switch and
will ignore the use of the Cage Emergency Stop. This function effectively promotes the Ground control
position to have overall authority over the machine, when selected.
10. Maintenance; Maintenance check lists;
Normal maintenance
 Visual check of switch operators, (Key switch) and connection wires.
 Check of power supply to verify it is correct.
 Check of the equipment correct operation, by selection of the alternate control position and then
checking that the green button is inert at the non-selected position.
11. Ease of accessibility and replacing of internal parts;
Replacement of parts should only be carried out by appropriately trained and competent persons.
Individual parts of the control devices can be replaced, ensuring like-for-like exchange of parts, security
of the wiring and polarity of components if applicable (Diode outputs etc.)
Only Niftylift original and supplied parts shall be used.
12. Means for easy and safe trouble shooting;
To check the operation of the load sensor system.
1. Power on the Niftylift and select the base control location.
2. Allow the power circuits to cycle and ensure the machine is ready for the command signal.
3. Press the base green button and observe that the machine is ready to function with no load in
the cage. (Machine runs, pump flow is available for machine functions.)
4. Leave the base key in the ground control position and climb into the cage.
5. Enable the cage controls and then press the cage green button or foot switch to enable the
machine functions. Check that no controls are active and that no functions are permitted with
the key in the 'ground' control position.
6. Have the base key switch position altered to the Cage position. Check that the control
functions are now transferred to the cage, and that all controls are active.
7. Dismount from the cage and check the ground controls are now inoperative. All checks are
then complete.
8. Power off the Niftylift.
13. Information explaining the applications for use relevant to the category to which reference is
made;
Not applicable
14. Checking test intervals where relevant.
Check the operation of the control position interlock at the beginning of every duty cycle.
