4 Safety instructions The Fundor T centrifugal casting machine is designed exclusively for casting dental alloys, with the exception of titanium. Any other use is considered to be improper. We shall not be liable for any damage resulting from improper use. CAUTION! Titanium reacts very strongly to the crucibles personal injury and damage to the unit are possible! During melting, alloys containing beryllium produce strong oxides that cause considerable wear to the crucibles and remain there in significant quantities. CAUTION! When beryllium is processed, carcinogenic particles are released. Wear mouth protection and ensure good suction extraction when casting and finishing! The safety instructions must be followed in order to avoid personal injury or damage to equipment. We shall not be liable for failure to comply with the safety instructions. General safety instructions l Place of use The unit has been designed solely for use in dental laboratories and comparable establishments for research, commercial and training purposes.

Working l The counterweight of the mould ist to be correctly adjusted in the clicking points in order to prevent the out-of-balace and so a moving of the machine when centrifugal casting. Danger of burns due to hot parts! l Wear protective clothing (protective apron), safety shoes, safety goggles and protective gloves. l Always use mould tongs to move moulds and hot crucibles. l Place hot parts only on a fireproof surface. l Carry out maintenance and cleaning work prior to casting or once the unit has cooled down. 5

6 Unit description The Fundor T is a benchtop machine for casting dental work. It can be used for precious metal, cobalt-crome and metal-to-ceramik alloys or no precious metal content. Centrifuging is started by closing the lid. The doublejointed arm optimises the centrifugal force. The starting speed is infinitely variable. The ingots are melted with a flame. We recommend to use for melting only the Multiplex melting torch for propane/natural gas/oxygen and for simplifying the setting of the flame the automatic gas lighter.

7 Installation Only a trained worker is allowed to install the Fundor T. Observe the safety information! l Place the Fundor T on a level worktop. Fundor T has to contact the working bench with all four feet. The front right rubber foot can be used for levelling - after opening side panel (see figure 1). l There is the possibility to screw on two feet. Open the right-hand side panel and unscrew the two rubber feet. Fasten the separately delivered feet and mark the fixing points at the bench. Drill holes in the worktop and screw the casting machine down with suitable screw (see figure 2). l Install the Multiplex melting torch next to the machine in a suitable position.the automatic gas lighter facilities enormously the firing and adjustingof the melting torch. It can be mounted at the wall or at the back of Fundor T (pos. 7 in fig. 4). When installing these units take notice of their instructions for use. Fig. 1 Fig. 2 7

8 Working Danger of burns due to hot parts! l Wear protective clothing (protective apron), safety shoes, safety goggles and protective gloves. l Always use mould tongs to move moulds and hot crucibles. l Place hot parts only on a fireproof surface. The counterweight of the mould ist to be correctly adjusted in the clicking points in order to prevent the out-of-balace and so a moving of the machine when centrifugal casting. 1. Switch main switch 1 on ( I ): green LED 2 will come on. 2. Lid 4 of the centrifuging chamber may be opened after about 15 seconds. 3. Set the starting sped required at switch 5 scale mark 4 for precious metal alloys for crown and bridges, scale mark 6 for precious metal alloys for metal-ceramics, scale mark 8 for alloys based on palladium, scale mark 8 for cobalt-chrome and nickel-chrome alloys. These are guide values. Infinitely variable adjustment makes other values possible. The optimal starting speed depends on the composition of the alloy, the temperature and the flow properties of the melt. Lower starting speed values may also be favourable for some alloys. 4. Turn the double-jointed arm 8 counter-clockwise so that the counterweight 9 stands at the right (fig. 4). 5. Set the counterweight for the size of mould being used by raising the weight, movingit and engaging it securely again. Example: for amould of size 3 approach the counterweight to the figure 3. If the counterweight is not se correctly, the out-of-balace of the centrifugal armmay move the machine. 6. Put crucible in its holder 10 and put casting metal in. Use for cobalt-chrome alloys and non-precious alloys low crucibles (Order-No ) and put the casting cylinderside bei side. 7. Put the mould on the mould holder 11 and adjust the height at lever 12 so that casting funnel and crucible opening align. 8. Push the crucible on the mould. 9. Switch main switch to Prepare ( ) symbol (switch springs back to I ): the yellow LED 3 flashs. The machine ist now ready for casting. 10. Ignite the Multiplex melting torch, adjust it and melt the casting metal. NB: Please observe Operating Instructions for Multiplex. 11. Close the lid when the moment for casting is reached. This starts the centrifuging, which takes about 20 seconds. 12. Turn the Multiplex melting torch off. 13. The lock will release the lid after about 15 seconds. Open lid, remove mould. 14. Switch main switch off ( O ). 8
