5. Safety instructions

The patient chair must only be used under the supervision of dental professionals.

This is to protect the operator, patient, and chair against injury and damage.

To make sure the patient is in the most ergonomic position during treatment, the operator

must maintain a clear view of the chair and patient at all times. In addition, the operator

must make sure the patient is sitting or lying in the chair correctly according to the

instructions below.

This is to protect the operator and patient from being squeezed or crushed.

Before moving the chair into a different position, the operator must check to be sure that

the area under the chair's components is completely clear.

CAUTION: This chair is designed for a maximum load of 268lbs/130Kg.

5.1 Position of the operator

The operator must position him/herself behind the patient chair next to the headrest,

facing the chair and the patient.

From this position, the operator can guide the patient into the correct sitting/lying position

and move the chair to the next position with his/her foot on the joystick.

5.2 Position of the patient

When the patient chair is moved to a new position, the patient must sit/lie with hands on

stomach or on the handle if the chair is equipped with such an accessory.

6. Warning signals and emergency stop

The patient chair is equipped with safety systems to protect you against injury and the

chair against damage.

6.1 Program stop

When the chair moves to a programmed position, it can be stopped by moving the chair's

joystick in one of the four directions.

6.2 Safety stop: Backrest

The backrest has a safety

function that stops the chair movement if

the backrest hits a knee or thigh, or if it is obstructed

in any other way.

When the backrest stops, the power to the chair's

motor will cut out and an alarm signal will be emitted.

When the obstruction has been removed, the chair can

be operated normally.

6.3 Limit stop

The chair is equipped with a limit stop to prevent excess strain

on the chair's mechanical components. When the limit stop is reached, the motor cuts out

and the chair can be moved away from the stop by pushing the joystick in the opposite

direction.

6.4 Integrated thermal cut-out

The chair's backrest and seat motors have integrated

thermal fuses that cut power to the motors if they are subjected to

harmful temperatures. This may occur if the chair is in constant operation

or the motors are overloaded.

The motors can be activated again once they have cooled down.

6.5 Emergency stop (accessory)

When the emergency stop button is pressed,

the chair's mains power is cut off.

If the chair moves to a programmed position and

the emergency stop is activated, the chair must be

moved manually to the backrest and seat

outer positions once the emergency stop

has been released.

6.6 Safety stop, chair lowering (accessory)

If the chair meets an obstruction when it is lowered,

it will immediately stop and lift slightly.

7. Starting up the patient chair

7.1 On/Off

The On/Off switch is under the footrest.

The chair must be switched off at the end of the

working day.

7.2 Adjusting the headrest

The height of the headrest can be adjusted

manually by pulling or pushing it to the

required height.

Caution! Fingers may get caught between the headrest

and the backrest.

7.3 Adjusting the position of the headrest

The position of the headrest can be adjusted by pulling the handle

away from the backrest.

After the headrest has been adjusted, it must be locked into

position by pushing the handle towards the backrest.

Caution! Fingers may get caught between the headrest plate

and the neck clamp.

7.4 Operating the armrest

The armrest on the chair is an accessory (can be

added later).

The armrest can be swivelled away from the chair to

make it easier for the patient to get in and out of the

chair. The armrest must be raised approx. 1 cm and

can then be moved to the position required for the

patient to sit down or leave the chair.

7.5 Adjusting the angle of the seat

The angle of the seat can be adjusted by pulling the release

knob under the seat.

The seat can be levelled out by pressing it down while

pulling on the release knob.

It may be an advantage to level out the seat when treating

children.

The bottom position is intended for use during

operation and must not be used when a patient

is getting into or out of the chair as this will put

an unnecessary strain on the footrest.

7.6 Adjusting the footrest

The footrest on the chair is an accessory (can be added later).

The footrest can be clicked into 3 positions.

Lift the stirrup to change the position.

If the stirrup is raised to the upper position (position 4), it will

be released and will return to the starting position.

Use the stirrup as a footrest only and not as a step.

8. Description of the joystick

The chair can be adjusted manually or automatically to the desired position using the foot

joystick.The chair can be equipped with up to 3 joysticks to make adjustment easier.

8.1 Manual adjustment of the chair

If you wish to adjust the chair manually, the joystick must be activated until the desired

position is reached.

8.2 Seat up

When the joystick is in the "Up" position,

the seat will be raised until the foot is

removed from the joystick or the seat has

reached its limit stop.

8.3 Seat down

When the joystick is in the "Down"

position, the seat will be lowered until the

foot is removed from the joystick or the

seat has reached its limit stop.

8.4 Backrest down

When the joystick is in the "Left"

position, the backrest will be lowered

until the foot is removed from the joystick

or the backrest has reached its limit stop.

8.5 Backrest up

When the joystick is in the "Right"

position, the backrest will be raised until

the foot is removed from the joystick or

the backrest has reached its limit stop.

A double-function joystick is available as

an extra accessory, i.e. the backrest and seat can be activated simultaneously.

9. Automatic adjustment of the chair

The chair has 4 programs that can be programmed as required.

If one of the 4 programs is used, the joystick will only need to be activated briefly in the

program in question. The chair will automatically move to the programmed position.

The 4 programs in the chair are set at the factory. Once installed, the programs can be

modified to suite the operator’s needs.

10. Programming the chair's positions

The chair must be manually set to the desired position.

Next, hold down the program button (located under the seat of the chair) and,

simultaneously, move the joystick to the desired program setting (P1 - P4).

The chair will emit a high-pitched sound. When the sound stops, the position has been

stored and the programming button can be released.

The same procedure applies to the setting of the other positions.

Once the positions have been programmed, the settings can be checked by briefly moving

the joystick to the program setting in question.

The programs will be saved when the chair is switched off.

The chair can be stopped while moving to a programmed position by

briefly pushing the joystick in one of the four directions.

11. Maintenance

The Centers for Disease Control and Prevention (CDC) recommends use of a chemical

germicide registered with the EPA as a Hospital Disinfectant and labeled for

tuberculocidal activity for surfaces that have been soiled with patient material. In

compliance with this guideline, we recommend intermediate-level disinfection between

patients using Sani-Cloth AF3. It is important to follow the manufacturer instructions for

use to ensure effective disinfection.

We recommend cleaning and disinfection at the start and end of each day as well as

between patients.

11.1 Cleaning of upholstery and armrest:

Material: UltraLeather™ (Imitation Leather upholstery)

Cleaning:

Wipe all surfaces using a Sani-Cloth AF3 cloth at the beginning and end of each workday

and between patients. Inspect and repeat this process if any visible soil or residue exists.

Discard the Sani-Cloth used for cleaning. .For stains, alcohol based cleaners such as

Fantastik® and Formula 409® can be used. To sanitize, use a solution of 1:5 bleach to

water. Rinse with clean water to remove cleaning solution residue. Allow to air dry.

Disinfection:

After each cleaning, disinfect using a fresh Sani-Cloth AF3. Ensure the surfaces remain

wet for the full three minutes. It is crucial that the Sani-Cloth AF manufacturer

instructions are followed EXACTLY to ensure effectiveness.

Agents that must not be used:

The following agents may cause permanent damage to upholstery and the armrest:



Wax polish



Alcohol



Acetone



Perchloroethylene



Trichloroethylene



Powder cleaning.
