Soft start
The chair features a soft start device for seat and backrest up-down movements. This device provides
a better sensation for the patient, because it stops the of jolts happening at the beginning and at
the end of the movements and this also increases the useful life of the motor.
Emergency stop
An “emergency stop” key is provided. When pressed, all functions and movements are automatically
interrupted. When pressed again, unit returns to operation, keeping the programming and positions
previously preset.
Bump preventing device
Always having in mind the dentist’s security, we developed the leg bump preventing device. When
the chair were descending, any obstruction below the chair would trigger this device, interrupting
all functions and preventing further complications.
Current surge protection
The equipment is endowed with high current, safety device that uses 2 fuses and internal overpower
protection for the equipment that is attached to the chair.
Electronic system
Chair features an low-voltage electronic system which allows complete interface with Gnatus
reectors, equipment and electronic water units, not only providing security to both patient and
dentist but also extending the components life.
List of pieces and circuit scheme
Gnatus Company declares that the supply of the circuit scheme, list of pieces or any other information
that propitiate technical attendance for the user, can be request if there is an agreement between
the user and Gnatus Company.
Attention

(mobile phone, wireless) land mobile radio, amateur radio, AM and FM radio transmissions and TV
transmissions can not be predicted with accuracy. Due to the RF xed transmitters is recommended
to install an electromagnetic inspection at the local in order to evaluate the electromagnetic
environment. If at the place where the Syncrus G8 Dental Chair is be using the eld intensity
level exceeds the conformity level for the RF above, is recommended to observe if the operations
are normal. Whether abnormal operations are observed, additional procedures shall be necessary
such as reorientation or replace the Syncrus G8 Dental Chair.

INSTALACIÓN DEL EQUIPAMIENTO
Attention
The Gnatus dental set is dimensioned so that the stability of the set composed of a Dental
Chair, Delivery Unit, Dental Light and Water Unit remains stable in normal conditions of use.
If, by option of the customer, it is necessary to install other accessories in the dental set.
Gnatus informs you that the evaluation of the stability is the customer’s responsibility, and
suggests that in this case the base of the dental chair is fastened to the oor by means of
the holes already furnished in its base. This means that the added weight does not jeopardize
the stability of the set.
How to x the dental chair base to the oor
Mark the oor, stick with 12mm drill, insert two S12 screw plastic plugs in the holes, place the chair
aligned to the holes and x it using 3/8” x 90mm hex head steel screws and washers.
Base pierced for option of fastening
the dental chair to the oor: 2 Holes
located on the side of the bearings
“outside” covered by the nishing
cover of the motor.
Minina area for the installation
of a dental set should be 10m ².
Warning: Screws, washers and
bushings with the product.
