Replacing the gas spring
On some models of the VS a servokit is mounted.
Below describes the proceedure of changing the
gasspring on the servokit.
Removal
1. With the seat in sitting position, raise the seat
lift to improve access from beneath.
2. Remove the front fixing screw from the
elevation actuator, see photo on right.
WARNING
The seat raises towards standing position by it self
when the elevation actuator is removed. Push the
back rest backwards as the actuator is removed, see fig.
When removing the actuators front end, carefully
place the actuator on the wheelchairs chassi.
The new actuator is calibrated at the factory and its
piston rod must not be turned while the actuator is
loose. If this happens, the actuator will need to be
calibrated and this requires special equipment.
Detailed information on calibration is given in the
technical manual for the ICS control system.
Before removing the actuator it´s recomendet that the
piston is taped up with the rest of the actuator to
prevent rotation of the piston.
3. Carefully lower the seat forwards, see photo
on right.
