Risk of injuries through
WARNING
leaking compressed air and
lashing pneumatic hoses
Open or loose pneumatic connections can cause
severe injuries.
Ensure that during installation and maintenance
of the pneumatic hoses and of the compressed air
regulator compressed air is not conducted through
the hoses and connections.
Before conducting compressed air through the
hoses and connectors, verify that the hoses are
securely inserted into the correct connectors and
that they are not damaged. This also applies to the
compressed air regulator.
Do not conduct compressed air through damaged
hoses and connectors.
The spindle may suffer

damage if the compressed air is contaminated
The incoming compressed air must be dry and oil-free
according to ISO 8573-1:2010 because the
compressed air regulator only serves as an indicator
for contaminated air.

Ensure that the compressed air meets the above
requirements.
Only connect the machine to the compressed air
supply if the compressed air regulator is properly
installed.
