Safety instructions
The HF Fornax® T centrifugal casting machine is designed exclusively for casting dental alloys, with the exception of titanium. Any other use is deemed to be improper. No liability will be accepted for any damages resulting from improper use.
WARNING
Danger from toxic gases!
Titanium reacts violently with the crucibles. This may lead to bodily injury and damage to the device!
•Wear suitable protective equipment when working with the machine.
•When casting dental alloys, do not use titanium!
Alloys containing beryllium produce strong oxides during melting, cause substantial wear to the crucibles and remain there in significant amounts.
WARNING
Danger from toxic materials!
Carcinogenic particles are released when beryllium is processed!
•Wear mouth protection and ensure good suction extraction when casting and finishing!
The safety instructions must be followed in order to prevent personal injury and damage to the machine. We shall not be liable for damage due to failure to comply with the safety instructions.

Repair work
Repairs may be carried out solely by BEGO customer service personnel or by persons authorized by the BEGO customer service department.
Metallic housings must be grounded properly so as to prevent them from carrying current. Otherwise they are extremely dangerous because the housings may be live due to damage to the machine! Since a check to ensure a de-energized state is mandatory after every intervention in the machine (Germany: check in accordance with DIN VDE 0701-1), only qualified electricians may open the machine!
Only BEGO replacement and wearing parts may be used.
Installation
The device is categorised under protection class I and may only be connected to properly earthed power sources (earth contact sockets).
When laying cables and hoses, make sure that they are protected from hot components (e.g., moulds).
The cooling water temperature must never drop below 10°C (50°F). If not observed, condensation forming on the coil may have an adverse effect on the heat output. If condensed water get onto the hot mould, it may vaporized explosively.
Danger of burns when draining the cooling water! The water can reach temperatures up to 70° C if the unit was used for casting beforehand.
Care and maintenance
Switch off the machine and pull out the mains plug before performing any care, cleaning or maintenance work.
Only use dry or slightly moist cloths for cleaning. Do not spray the machine with water or immerse it in water.
Maintenance of safety-relevant components
The unit has been designed for a service life of 10 years from the date of manufacture. No liability is accepted for damages arising from operation of the unit after this period.
Safety-relevant components must be checked regularly and replaced as required. This work must be carried out solely by BEGO customer service personnel or by repair centres authorised by the BEGO customer service department. For that purpose, regular maintenance, including annual inspections and an inspection after five years, carried out by personnel authorized by BEGO is recommended.
