1.12 Safety during operation
WARNING!
Before switching the milling machine on, make sure that there is no risk of personal
injury or damage to property.
Avoid any unsafe work methods:

The instructions mentioned in these operating instructions have to be strictly observed
during assembly, operation, maintenance and repair.

Do not work on the milling machine, if your concentration is reduced, for example, because
you are taking medication.

Clamp the workpiece securely and firmly before switching on the milling machine.
WARNING!
When chipping magnesia materials (aluminium-/magnesium alloys), spontaneously
inflammable or explosive particles (powder, dust, chips) might be generated, which
might cause a fire and/or explosion (deflagration).
Magnesium is designated a dangerous material in the list of dangerous materials and
preparations according to para. 4a of the Ordinance of Hazardous Substances.
In case of a fire with magnesium, only use appropriate and admitted extinguishing
agents. Never extinguish using water. If burning magnesium is extinguished with water,
this might lead to dangerous reactions (hydrogen gas). Water would be decomposed in
its components hydrogen (H) and oxygen (O).
Only the following extinguishing agents are permissible:

solid extinguishing agent of fire class D (fires involving metals)

dry covering salts for magnesium

a mixture of sand and cast chips

argon (Ar) or nitrogen (N

)
If fine mist and smoke is generated at the workplace, suction units must be provided in
order to avoid the accumulation of ignitable mixtures and emissions.
We specifically point out the dangers in the description of work with and on the drilling machine.
1.13 Safety during maintenance
Inform the operators in good time of any maintenance and repair works.
Report all safety relevant changes and performance details of the milling machine or their ope-
rational behaviour. Any changes must be documented, the operating instructions updated and
machine operators instructed accordingly.
1.14 Switching-off and securing the milling machine
Turn off the main switch of the milling machine before starting any maintenance or repair work.
Use a padlock to prevent the switch from being turned on without authorization and keep the
key in a safe place.
All machine parts as well as all dangerous voltages are switched off.
Excepted are only the positions which are marked with the adjoining pictogram. These positions
may be live, even if the main switch is switched off.
Place a warning sign on the milling machine.
WARNING!
Live parts and moves of machine parts can injure you or others dangerously!
Proceed with extreme caution if you
the milling machine due to required works (e.g. functional control).
