USER MAINTENANCE

Described here are the servicing and preventive maintenance procedures that are required in the day to day operation of

the ProX® DMP100 printer . The following safety rules are applicable for all procedures .

Caution: the machine is not allowed to run a job during a maintenance .

Caution: perform only tasks you are authorized and certified to complete.

Caution: presence of metal powder. Do not use or manipulate any material without first reading the

safety datasheet (SDS) for that specific material.

Caution: Personal Protective Equipment (PPE) must be used to protect the user against health or

safety risks during working tasks . Wear disposable rubber gloves, anti-static coverall, anti-static safety

shoes and safety glass . Wear disposable dust mask rated FFP3 or N99 level protection at minimum ; we

recommend the use of powered air-purifying respirator .

WARNING: FINE METAL DUST IS HIGHLY FLAMMABLE . AVOID USING ANY IGNITION SOURCE NEAR THE

MACHINE (OPEN FLAME, SPARKING, ELEVATED TEMPERATURE PARTS) .
