WARNING
Danger to life due to unintentional starting of the drive unit
Unintentional starting of the drive unit can cause death or severe injury.
• Make sure that the drive unit cannot be started accidentally.
• Post a warning notice to this eect at the point where the switch is located.
CAUTION
Burns caused by hot surfaces
Some parts of the frame of electrical machines can reach temperatures in excess of 100°C.
Touching components when the machine is in operation can cause burns.
• Do not touch frame parts while the machine is in operation or immediately after machine
operation.
• Allow frame parts to cool o before starting any work.
CAUTION
Burns due to escaping hot oil
Exiting hot oil can cause burns.
• Before starting any work, wait until the oil has cooled down to below 30° C.
CAUTION
Chemical burns and irritations caused by 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.
CAUTION
Injuries caused by stirred-up foreign bodies and dust when working with compressed air
When you clean using compressed air, this can stir up dust, metal chips and cleaning agents,
and so cause injuries.
• When cleaning using compressed air, make sure you use suitable extraction equipment and
wear protective equipment (safety goggles, protective suit, etc.).
