Dear Customer!
The RETOCAST T flame casting centrifuge is a compact tabletop unit with a double wall
stainless steel housing and a manual timer for precision casting. With three tightening
speeds, metals and investment materials of all kinds are used and cast. The centrifugal arm
has a counterweight to ensure smooth, quiet running and alloys are cast even into the
thinnest cavities within the casting ring, excluding metal waste.
Any other use or usage beyond this scope is considered unintended use. The manufacturer
shall not be responsible for any damages that may result thereby.
Prior to installation of the device operating instructions and especially the safety instructions
must be read and followed by all personnel who use this device.
After having unpacked the device, please check carefully whether transportation damages of
any kind have occurred. If that is the case, the carrier or manufacturer must be notified within
3 days. The company will not be responsible for any damages found after that.
These operating instructions must be read and followed by all personnel who use this device.
To ensure quick access we recommend to keep it at a safe place near the device. In case of
loss it can be ordered from the manufacturer.
