SHUTTERS OPERATION
Drive for a crank with Cardan joint:
In blinds equipped with a crank lifting mechanism with a cardan gear, the crank is supplied with a blind.
After installing the blind, place the crank rod in the gearbox through the hole in the roller shutter box. Next
- depending on the type of blind installation - the crank should be screwed to the box or using wall plugs
to the wall of the building. An additional element fixing the crank arm is a special clamp, which is screwed
by means of screws (dowels) to the wall in the lower part of the crank arm. The design of the crank arm
thanks to special joints allows you to "straighten" it for aesthetic purposes when the blind is not operated.
To raise or lower the blind jacket, turn the crank in the right direction.
The operation of the crank lifting mechanism requires special care and feeling, as the gear used allows
for obtaining large forces that may damage the shutter elements. Therefore, stop turning the crank when
you feel resistance or notice that the roller shutter has stopped when lowering. In external blinds, the
rotation of the crank clockwise causes lowering of the roller shutter, while the rotation of the crank
counter-clockwise causes the roller blind to be lifted
