Opening the casting chamber cover and removing the casting ring
The centrifugal arm must be at a complete standstill before the green READY indicator (Fig. 3-1) lights
up and the red CLOSED indicator (Fig. 3-8) goes out. The casting chamber cover can now be opened
and the mould ring removed.
Risk of burns when removing the hot mould ring. Always wear protective gloves and use
the proper tongs to remove the mould ring and the crucible.
Do not use force to open the casting chamber cover.
A locking mechanism prevents the casting chamber cover being opened during casting
until the centrifugal arm is coming to a stop.
Switching off the casting machine
You can switch the machine off using the ON/OFF switch (Fig. 2-5)
Note: For the faster cooling the casting machine should not be switched ff between castings. It
should not be switched off by the ON/OFF switch until the final casting cycle has been
completed.
Note: The casting machine automatically cuts off the water supply after casting. The water tap
therefore does not have to be closed after each casting procedure, but it should be turned
off, if the casting machine is not being used for a longer period, e.g. over the weekend.
Using the STOP button
The STOP button (Fig. 3-5) is not required if the casting machine is used properly. It should only be used
when the program cycle has to be interrupted because of an error or fault. Pressing the STOP button
immediately stops the work in progress, e.g. melting the metal.
MAINTENANCE
Always disconnect the casting machine from the mains during any servicing, cleaning
and maintenance work.
There should always be two people with electrical experience present when servicing
and repairs are being carried out.
All work on the electrical components of the casting machine should only be carried out
by a qualified electrician.
