The HT500 is recyclable due to its low-pollution
equipment. Nonetheless, the European Guideline
2002/96/EG (Waste Electrical and Electronic
Equipment - WEEE) and the German Elektro- und
Elektronikgesetz
 (ElektroG) forbid the disposal of
the apparatus via the household garbage. For
environmental friendly recycling and disposal of
the HT500 please contact a certified electronic
waste management professional.

INFO

Kühling&Kühling emphasize that there is no
redemption obligation in this regard.

Personnel safety and device reliability

The HT500 features state-of-the-art design and construction and has been built and tested thoroughly
so that it is safe and ready to use at delivery. Nonetheless, hazardous situations may appear due to
the production process itself and property damage may be caused by false operation.

The risk of experiencing hazardous situations is increased by:

Using the HT500 for other applications than the intended.
Inappropriate usage of the 3D Printer.
Operating the 3D Printer in a non-safe state or under improper conditions.
Insufficient attention, lax handling or intensive soiling.

Therefore:

Use the HT500 for its intended use only.
The HT500 must be in goor working order
and in a safe state at any time. Check the
apparatus prior to every commissioning
and at regular intervals for wear, damage
and cleanliness.
Ensure that nobody can be injured by
parts of the 3D Printer.
Fix any error condition or visible damage
immediately. If prompt rectification is
impossible, decommission the 3D Printer
and do not put it back to use unless all
problems have been solved.
Regard the local accident prevention
regulation.
Provide access to the operating manual for
anybody operating the machine.

INFO

The manufacturer cannot be held liable for
injuries and damages due to inappropriate
usage of the HT500.
Inappropriate usage of the HT500 voids the
manufacturer's warranty.
