11.3 Gas pressure spring replacement
If the mobile arm does not park in highest or lowest
position but falls or raises slightly by itself, tighten the
4 bolts indicated with the letter “C” in pic 2. If the arm
still does not park or becomes heavy to adjust, the gas
pressure spring must be replaced.
Attention!
Due to high weight and complexity it is
recommended to be two persons or one person with a
lifting device when performing this service.
1. Remove the four screws fastening the cover
that is located on either side of the arm. (pic 1)
2. Place the parallel arm in the far most upright
position. (pic 2)
3. Before removing the pins holding the gas spring,
as much pressure as possible from the gas spring
should be relieved. To do this, raise the arm slightly
until the pins are loose.
Attention! At all times when the gas spring is
not securely in position with pins and locking rings,
the arm can fall down heavily from it´s upright
position and cause injure to persons.
4. Remove the locking rings and the two pins. Move
the gas spring slightly upwards/forward and then
remove it. (A in pic 2)
5. Place the new gas spring in the same direction as
the old one. Reassemble in the reversed order.
Attention!
Ensure that the locking rings are
refastened properly.
