You will need a fully qualified engineer to install a spring break device.

  1. The pawl retaining pin is only renewed after the spring fully tensioned as indicated on the yellow tag on the spring break device.
  2. You now need to attach the spring break device to the spring, remove the pawl wheel from the spring break device, then make sure the pawl is always at 12 o’clock.
  3. The large washer should always be kept at the following position: 2 small spacer washers and the large washer on top, this allows the bracket to move. Make sure the large washer is always at the back of the baring plate.
  4. Remove the two nuts and slide it onto the shaft, level the spring to the centre baring, and secure the spring break by tightening the two screws, you should be left with free movement at all times.
  5. Then take the pawl wheel which you removed earlier, slide it onto the shaft making sure the screws are always facing outwards.
  6. Take your key steel, fit it into the pawl and then tighten everything using a DEVICE NAME HERE!?
  7. The pawl retaining pin must not be removed until the spring is fully tensioned.

When larger springs or drums are supplied then Extension Brackets are used to achieve the correct dimensions and strengthening brackets are supplied on the larger doors. You can find out more information on these here.

Once the spring device is fitted correctly and the spring is fully tensioned, this is when you can remove the retaining pin. Please view the video below to see this in action.
