Dear Customer!
The RETOCAST T flame casting centrifuge is a space-saving benchtop unit with a double
wall stainless steel housing and electronic timer for precision casting that is suitable for both
precious and non-precious alloys and model casting. The proven technology of a centrifugal
arm, in combination with different starting speeds and timer control ensure that 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.
Store it at a safe place near the device. This documentation is protected by copyright.
Transmittal or reproduction of this document in whole or in part and disclosure of its contents
