1 - HANDLING AND SHIPMENT OF THE DENTAL CHAIR 1.1 - General procedure

IMPORTANT INFORMATION AND RULES WHICH MUST BE READ ALONG WITH THE INSTRUCTIONS FOR USE.

An ID code and warning symbol are stamped on each rod (see instructions manual).

The rods have been treated with rust-preventative and must only be used to lift and handle the dental chairs indicated in the instructions manual.

The rods must not be used for any other purpose than that specifi ed in the instructions.

The rods must be kept in a suitable sheltered place to prevent the material from rusting or deteriorating.

The rods must be used together to avoid placing too great a load on only two of them causing them to bend or be damaged.

1.2 - Instructions for use

- do not change the set-up of the dental chair (it should remain as it was in its packing) or apply any other weight. - when the chair is being handled make sure the load remains perfectly level to prevent all the weight from bearing down

on two levers and just one operator.

- each time the rods are used make sure that the tooth of the rod is correctly inserted in the rectangular slot provided (see attached illustrations).

- periodically check the condition of the rods.

- these rods can only be used for handling ANTHOS A2.0 dental chairs.

- the overall weight of the dental chair is 110 Kg whereas the dental unit weighs 70 Kg.

- Remove the arm from the plastic support (fi g.28 point c) being careful to make sure the spring does not come out of its seat. Once the arm has been removed, a set of holes marked with a number (fi g.29) can be seen. One end of the spring will be secured in one of these holes (fi g.28, point e).

- Remove the spring and position it in the hole required (fi g.29). To make the arm spring back more quickly, place the spring in a hole marked with a higher number than the previous one. On the other hand, to slacken the arm a little, place the end of the spring in a hole marked with a lower number than the previous one.

- Reposition the spring on the arm between the new hole and the stop seat provided (fi g.28, point f). - Install the arm in the support again.

- Make sure the end of the spring is correctly placed in the hole at the bottom of the support (see fi g.28, point h). - Re-install the pin carefully in order to secure everything in place.

- Once the arm has been secured to the board, put back the two plugs.

23 - PADDING THE SEAT OF THE DENTAL CHAIR

The padding of the chair is fastened by four screws in the front as indicated in the drawing (Fig. 30). On the contrary the padding of the backrest, of the armrest and of the headrest are fastened by fast connections which, if necessary, can be set with a screw driver in d.

Before adjusting, loosen all the quick-couplings “d” so that they protrude by 1 mm (A – Fig 31).

If further adjustment is required, fi t an O-ring (code 97362000) over the internal tabs of the quick coupling (d). Fig. 30

25 - RAISING THE DENTAL CHAIR

Inside every chair there is a sectionable feeding cable of the backrest return motor.

This sectioning is placed under the connection box cover (doctor side) and can be used when the dental chair is completly down too.

In fact, unscrew the four screws of the cover and insert a hand as shown in the fi gure 34.

Feeding directly the motor with a 230 Vac cable and positioning this one between the central point and one of the two extremes (see fi g. 33), the dental chair moves up or down. In this way the connection box is ready for the technical intervention.
