a qualified technician or your local representative.

functions are described below.

An obstruction between the backrest and the floor when driving down the
chair and/or the backrest stops downwards chair and backrest
movements. Remove the obstruction to resume normal operation.
2. Chair
An obstruction between the chair and the floor stops downwards chair
and backrest movements. Remove the obstruction to resume normal
operation.
3. Legrest
An obstruction between the legrest and the floor stops downwards chair
and backrest movements. Remove the obstruction to resume normal
operation. The location of the safety switch depends on which legrest
your dental unit is equipped with.
