MAINTENANCE AND USE MANUAL

DUNE

The DUNE has been designed to sandblast items used in the odontotechnics field. The DUNE unit is available as the DUNE Mod.2 (two nozzles) and the DUNE Mod.3 (three nozzles). The constant-pressure tungsten carbide nozzles are available in various sizes so that the technician/operator can set up a sandblaster that meets his requirements perfectly. The following items are supplied as standard:

• n.2 nozzles ø 0.8 mm fitted on handpieces for DUNE Mod. 2

• n.3 nozzles ø 0.8 mm fitted on handpieces for DUNE Mod. 3.

The tank cylinders feature an efficient constant vibration system, specially designed to keep the sand on the move at all times; this prevents the formation of lumps which might obstruct the nozzles. Furthermore, a new air pumping system inside the cylinders themselves ensures that all the sand exits the cylinders, thus eliminating the problem of continuous top-ups and breaking up any lumps of sand that have been caused by damp.

Because there is a not just one cylinder but a set of them the equipment features a switch for

fast sandblasting change-overs: This makes work easier when different types of sand need to be used. DUNE Mod. 2 is built so that an optional third cylinder unit with pressure reducer, gauge and handpiece body can be added if desired.

WARNINGS AND PRECAUTIONS

CHAPTER 6: INSTALLATION AND FIRST-TIME USE

So as to provide greater clarity the numbers given in the diagrams in this chapter correspond exactly to the numbering in the Components Table (Ch. 3).

Work area lighting is an important factor in both personnel safety and the ultimate quality of the work being done. In Italy lighting must comply with a Ministerial Decree Law that clearly defines minimum lighting requirements. In other countries lighting requirements form part of the accident prevention and workplace hygiene standards.

Before proceeding with installation make sure that all relevant safety conditions prevail and

follow the instructions below carefully.

6.3

REQUIRED WORK SPACE

Choosing a good workplace with an appropriate amount of space available for equipment installation is an essential factor in personnel safety, the quality of the work and proper maintenance. This zone must not only be spacious enough to allow for optimum equipment operation but must also be well illuminated, aired, not dusty and not exposed to direct sunlight.

6.2

PERMITTED AMBIENT CONDITIONS

Unless stated otherwise at the time of order the equipment will be configured to operate properly under the following ambient conditions:

Ambient conditions other than those listed above may cause malfunctions or sudden breakdowns. Lighting in the installation area must be sufficient to provide good visibility at every single point on the equipment. More specifically, luminosity must not be less than 200 lux, lighting must be as uniform as possible and there must be no reflected light as this could dazzle the operator.

Min ambient temperature 0°C Max ambient temperature 40°C Max humidity 90%

The DUNE features a system that blocks the flow of sand when the sandblasting control is released, thus optimising consumption. This device also maintains the pressure inside the cylinder and so improves equipment response times when the sandblasting control is activated. The vent valve (on the cylinder lids) is used to release pressure when the equipment is off and so allows the lid itself to be opened.

7.4

RESIDUAL RISK

Residual risk is:

• a danger that cannot be completely eliminated through design and application of safety devices.

• a potential danger which cannot be highlighted.

Sandblasting equipments are units which generate a variable-pressure outflow of sand through the fitted nozzles; it therefore follows that the residual risks are as follows:

• being hit by jets of sand as a result of accidental opening of the glass hatch.

• work carried out on the equipment interior by unauthorised personnel.

To prevent accidents always observe the instructions in this manual. Should you have any doubts at all please contact the manufacturer Zhermack S.p.A. or your Authorised Servicing Centre.

Before using the sandblasting equipment it is always advisable to lower the glass hatch.

CHAPTER 8: MAINTENANCE

8.1

CLEANING

The equipment exterior can normally be kept clean just by wiping it with a dry cloth. If necessary, wet the cloth just a little water or use a non-degreasing detergent.

The operator must ensure that the equipment is kept clean and free from any foreign bodies such as dirt, water, non-conducting liquids etc. The equipment must be cleaned at the end of every work session to remove all residues. Cleaning must be done with the equipment at standstill and positioned in a stable manner.

Never use inflammable, corrosive, alkaline or toxic liquids when cleaning the equipment.

Eye goggles and a face mask must be worn when using compressed air for cleaning purposes. Do not allow any persons near the equipment as they could be hit by flying dust.

Before cleaning the equipment exterior always turn the main switch to OFF. It is strictly forbidden to clean the equipment while it is connected to the mains power supply.

Fig. 11 : Remove the closure plug on the front of the frame (10); bring the sandblaster onto the edge of the

support top. Open the glass door by pulling the lower

extremity upwards. Remove sand residue by letting it flow out through the special aperture on the frame; collect the sand in a recipient as it flows out.

Carry out the cleaning tasks described below with extreme caution. Bear in mind the weight and size of the equipment (see Section 4.2) and, if necessary, carry out the following tasks with the aid of another worker.

8.1.1

Cleaning the inside of the sandblasting equipment

To empty residual sand from the sandblaster proceed as follows:

Elimination and/or recycling of the used sands (and, consequently, sandblasting process residues) must be carried out in compliance with EC directives or according to the laws in force in the country of use.

If the DUNE is not to be used for a prolonged period it is advisable to disconnect the equipment from the electrical power supply.

ROUTINE MAINTENANCE

8.2

CHANGING THE LIGHT BULB AND/OR REACTOR

Once the equipment has been cleaned (see section 8.1) the operator must check for worn,

damaged or loose parts. If any such anomalies are discovered contact your Authorised Servicing Centre.

Should any of the above anomalies be discovered it is strictly forbidden to restart the equipment before such faults have been set right.

Equipment safety devices/guards must never be removed except for repair and maintenance purposes. Such items must be replaced as soon as the situation which led to their removal no longer exists and in any case before the equipment is used again.

More precisely, should the operator note any defects or problems of any kind whatsoever he/she must place a warning sign on the equipment indicating that maintenance work is in progress and that using the equipment is forbidden (EC-compliant signs can be purchased from the relevant suppliers). Routine maintenance, cleaning and proper equipment use are essential factors in guaranteeing long-lasting equipment performance and safety.

RESTARTING AFTER A LONG PERIOD OF INACTIVITY

Should the equipment need to be restarted after a particularly long period of inactivity proceed as described in Chapter 6 (First-time Use). If there are any faults or malfunctions proceed as described in Chapter 9 (Troubleshooting). If the problem persists or is not covered by the information in this chapter contact your Authorised Servicing Centre immediately.

Modifications which alter the equipment characteristics from a safety and risk prevention viewpoint may only be made by the Manufacturer who shall then issue a certificate stating that the equipment conforms to safety standards. Therefore any modification or maintenance tasks not actually described in this manual are to be considered forbidden. If the equipment is modified, tampered with or repaired by unauthorised personnel or non-original spare parts are used the manufacturer is relieved of all responsibility. If a maintenance task is required but is not described in this manual you must contact the Zhermack S.p.A. or an Authorised Servicing Centre.
