5.1 Safety
notices
Before carrying out maintenance and repairs, turn the main switch to '0' or 'off' and secure it
against being switched on again by means of a padlock. If the machine must remain ready for
operation during certain repair work, particular care must be taken. Make sure that there is no
possibility of personnel staying in the danger area; if necessary, secure against unauthorised
access by additional barriers.
Repairs may only be carried out by authorised engineers or by Parker personnel.
Work on the electrical equipment may only be carried out by engineers qualified for such work -
the relevant regulations must be followed (IEC..., EN..., national accident prevention
regulations).
Where it is necessary to dismantle safety devices during set up, repair and maintenance work,
the safety devices must be refitted immediately on conclusion of the work. The machine must be
disabled before disassembly.
As the whole system can be exposed to steady-state vibration during operation, all screws and
nuts must be secured.
For this, the following are used, dependent on the situation:
Loctite 243 or a Schnorr lock washer. Unless otherwise indicated, use Loctite 243.
