Gas pressure spring replacement
If the mobile dryer does not park in highest or lowest posi-
tion but falls or raises slightly by itself, tighten the 4 bolts
indicated with the letter “C” in fi g 2.
If the dryer 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 rec-
ommended 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. (fi g 1)
2. Place the parallel arm in the farmost upright position.

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 create great danger.
4. Remove the locking rings and the two pins. Move the
gas spring slightly upwards/forward and then remove it.
(fi g 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.
