Other safety-related measures
CAUTION
Personal protective equipment when using chemical cleaning agents
Chemical cleaning agents can be caustic or emit dangerous fumes.
If these come into contact with skin or if you inhale the fumes, this can cause injuries (e.g.
chemical burns on the skin or respiratory passages, or skin irritation).
During cleaning, make sure that appropriate methods of extracting fumes are in place and
that you wear the appropriate protective gear (e.g. gloves, goggles, face masks).
If using chemical cleaning agents, observe the instructions and any warnings provided in
the relevant safety data sheet. Chemical cleaning agents must be suitable for use with the
machine's components, particularly where plastic components are concerned.
Personal protective measures when working with compressed air
When you clean using compressed air, this can stir up dust, metal chips, or cleaning
agents, which can cause injury.
When cleaning using compressed air, make sure you use suitable extraction equipment
and wear protective equipment (safety goggles, protective suit, etc.).
