Dear Customer!
The wet trimmer ROTOGRIND MINI is characterised by a particularly favourable price-
performance ratio. The powerful motors provides a precise finish with high surface quality.
The stainless steel housing is extremely robust and durable. For safety reasons the device is
equipped with a safety fuse in case of power failure. The device’s front cover can be easily
removed with two special quick releases for cleaning purposes or disc exchange. Clean the
device’s front under running water in the sink. Stainless steel ensures durability and long-
term visual attractiveness.
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.

Specific Safety Notes 2.2
Note
:
•Investment material and dry hard plaster reduce the grinding disc’s service time. The
diamond grinding discs may not be used for metal and quartzide material. The diamonds
will start to melt immediately and the grinding disc is rendered unusable.
•The ROTOGRIND MINI includes a wet-rinsing, cleaning the grinding disc. When working
with material containing components which are not meant to be put into the public
wastewater disposal, suitable cleaning systems have to be used or the wastewater has
to be collected and disposed of separately.
•Keep the housing clean and dry.
•The ROTOGRIND MINI is a benchtop unit. Supporting surfaces should be straight, flat
and adequately stable.
•When opening the machine’s front, please keep in mind that the grinding disc doesn’t
stop immediateley after the machine has been turned off. Wait till it has stopped
completely.
•Always wear goggles when working with the device.
•Always use a wedging block when working on smaller pieces.
•Put the working piece on the model tray first and then press it towards the grinding disc.
•Never put your hands into the running device.
•Only turn on the machine again when the grinding disc is still at a halt.
•Don’t use worn or damaged grinding discs.
•Only change the grinding disc when it stands still and the whole unit is unplugged.
•Only use original REITEL grinding discs – with an outer diameter of 250 mm. Using
grinding discs supplied by other manufacturers will render our warranty null and void with
immediate effect.
•Always respect the regulations of the grinding discs manufacturer (e.g. max. speed,
sense of rotation, cutting speed, material to be worked on).
