1.2. TROUBLESHOOTING
Mistake
Possible cause and solution
Manual height adjustment does not work
There is too much load or uneven load on the chair.
Try to adjust the height without sitting in the chair. If
this does not work, the gas cartridge is defective and
should be replaced. Contact your VELA supplier
The brake function does not work
The brake is not activated. See section 1.9.6
The armrest seems loose
One of the hand screws might be loose. Tighten the
hand screw
The chair rolls badly
Wheels are blocked. Clean the wheels for wire residue
and the like.
Brake rod or chassis is in the way when I move in the
chair
You have a chair with seat rotation. Use seat rotation to
straighten the chair. See section 1.9.11
If the above does not solve your problem, you should contact your VELA
supplier.
