15. For secure reason use two or four plastic ties over plastic case.

16. Place a mechanical hinge construction back.

17. Plug both handholds (take care right and left) by "Click" and scrue two screws on the top of a mechanical hinge construction. Well done.

8. Apply DC voltage 5 to 12 V limited to 0,2 A and now the motor have to start rotate hast. Change polarity to change rotating direction.

9. Whene Dc voltage is apply, hold a cogwheel and observe current. By slow rotation of cogweel for one circle current have to stay in same value. If not, a wireing of motor rotor is demaged.

10. If the motor is good you can assembly all pieces back.

11. First plug the moving rod and half of the plastic case from a mechanical hinge construction, rorate it down.

12. Place the rod with cogwheel and the motor on it positions in botton of plastic case plugged to the right side of a mechanical hinge construction.

13. Apply small amount - drops every cm of fast glue (cianocrilat) on botton of plastic case and place top part of the plastic case over and press it together for 20 minutes or more. Use elastic strips or pliers with elastic on handles.

14. After glue is cured check movements of the linear attenuator by applying DC voltage to motor pins.

Hi,

today I fixed the motor which rotate the handholds on the front side via a mechanical hinge construction, see Steps 6 and 7.

To fix the motor you have to do:

1. Unplud two wire connector on botton of the motor.

2. Remove two screws on the top of a mechanical hinge construction.

3. Rotate ich handhold to the oposit direction and tear it off. Now a mechanical hinge construction is free.

4. By use a metal wires of resistor or other element pluged in motor pins, you can try move a linear atenuator in and out (rotate a motor) by aplly DC voltage 5 to 12 V limited to 0,5 A. Change polarity to move it in out. In my case motor did not turn, so I proceeded.

5. With knife open plastic case of a linear atenuator on welded line and dissasembli it to basic parts: 2 half of case, motor and the moving rod.

6. To unplug the moving rod and half of the plastic case from a mechanical hinge construction, rorate it up.

7. Try to rotate a motor rotor cogwheel. Rotate a big plastic cogwheel and a rod on left side have to move in out.
