These are general instructions and some variations may be needed depending on the tender. Eg the weights may need to be repositioned to the sides of the tender, or the tender securing screws may need to be moved to new positions to make room for the actuator. A little thought and the actuator can be made to fit inside any none motorised tender.

It is recommended that dry runs are done using thin double sided sticky tape before finally fixing the components into place.

The locating hook has been prized off, cut into two pieces and repositioned to either side of the tender body.

7. Glue the actuator in place so the loop in the actuator arm is directly over the hole in the floor.

8. Attach the lifting arm to the actuator arm and pass it through the hole.

9. Attach the coupling bar to the pivot plate and mark the lifting arm where it would pass through the hole in the rear of the coupler.

10. Remove the coupler and the lifting arm. Bend the lifting arm through 90 degrees at the marked place.

11. Refit the lifting arm to the actuator arm then refit the coupler and attach it to the lifting arm.

12. Solder the diode across the terminals of the actuator. Solder the blue (common) wire to the silver band end of the diode.

Then for none sound decoders use either (F1) the green wire, or (F2) purple wire on ESU or brown wire on Zimo, or even the white or yellow if need be, to the other terminal of the diode.

13. Final adjustment of the coupler height can be done by bending the actuator arm.

1.  Remove the rear wheels, any break roding and the tender body from the tender.

2.  Set the pivot plate in a position to ensure the outer edge of the coupling bar extends no more than 1mm outside the buffer heads.

The pivot plate can be fitted either way round.

3.  Check the height of the coupler against a wagon and that it is parallel to the track before fixing it permanently.

4.  The pivot plate may need to have a packing piece between it and the tender floor to lower it closer to the track.

5.  If the rear of the coupler interferes with the rear axle then this can be corrected by first dipping it in hot water then the coupler bar can be bent upwards.

6. Then cut a hole in the floor about 6mm diameter.
