For tooling changes make sure that the upstream process (feeding system) supplies the correct
parts matching the new tooling of the PARU Mini. Otherwise it may be damaged by handling of
the wrong parts.
PARU Mini is designed for continuous automatic operation. Information on wear cannot be provided as
such wear varies depending on the system (PARU Mini - tooling - parts handled) on hand. Recommended
maintenance intervals are as follows:
Notice!
Clean the drive with a clean non-linting cloth and isopropyl alcohol, soap suds or cleaning
solvent.
Notice!
The drive units basically require no maintenance. They require cleaning only when soiled or after
coming into contact with liquids.

Wear following personal protective equipment:
•
Foot protectors (safety footwear)
•
Hand protectors (safety gloves), if necessary
Before starting any maintenance work, switch off the machine using the main switch (supply circuit
disconnector) and lock it off with a padlock to prevent inadvertent starting.
If appropriate, affix the 'Do not switch' sign in a conspicuous place at the disconnectors.
Notice!
Be careful when working on and with motors/electromagnets! They can get hot during operation.
Therefore let motors cool down before working on them. If this is not possible, take suitable
protective measures such as the use of gloves.
Danger!
Maintenance work must be performed by professionals only.
•
Inspect/check the electrical equipment of the drives at regular intervals of time. Remedy defects like loose
connections or charred cables without any delay.
