Making The Machine Safe On Shutdown; Cleaning The Machine; Electric Motors; Servicing Work - Hettich BlueMax Mini Modular Instructions De Service

Recommendation:
Only use genuine replacement parts.
Replacement parts, items of equipment not tested and / or
approved by Hettich FurnTech GmbH & Co. KG may impair the
machine's active and passive safety.
In all work, refrain from applying any abnormal level of force
above and beyond the extent necessary to undo / fasten
connections and/or screwed joints.
For maintenance work, only use suitable tools that are in
proper technical working order, using them correctly and in a
way that meets the safety requirements.

3. Making the machine safe on shutdown

• Switch OFF the power supply to the machine (unplug).
• Detach the compressed-air hose (compressed-air supply).
• Prevent the machine from being switched back on again
without authorisation.
• Clean the machine as described in the relevant section.
• Affix a warning sign to the machine in compliance with
accident prevention regulations.
Danger!
CAUTION! Servicing work in progress!
DO NOT switch machine ON
Ensure good pollution-control practice
Contaminated dirt (washing water, oils, greases) must be
collected and disposed of in accordance with regulations.
Observe the pertinent regulations (e.g. law on waste
management). After cleaning, coat the machine's bare metal
parts
with preserving oil.
If necessary, coat rubber and plastic parts with talcum
powder.

4. Cleaning the machine

The entire machine must always be cleaned after it has been
used. This is best done by wiping it down with cloths and / or
vacuuming it with an industrial vacuum cleaner.
Note:
Never use compressed air to blow the machine clean.
This would take dirt to the remotest corners of the machine,
forcing it in particular under the sealing lips of ball bearings
and similar components.
Danger!
On account of the risk or shorting, only clean electrical
components (drives, switchgear etc.) in a dry state
(cloth) or protect them with appropriate covers.
Clean at shorter intervals if operating conditions make this
necessary.
Clean the machine
• only by suction, never by blowing it clean with compressed
air, and
• only with a dry cloth to remove left-on lubricants etc.
Follow health and safety regulations and relevant provisions
when handling hazardous and/or groundwater-polluting
liquids (e.g. oil, cleaning agents or solvents as well as other
chemical substances).
Never clean hands with aggressive, highly flammable and
health-harming solvents or cleaning agents.

Electric motors

All electric motors must be cleaned at regular intervals
because dirt and dust act as a insulating layer, possibly
causing motors / coils to overheat.

5. Servicing work

Work on the pneumatic system

Before working on the pneumatic system, clean the machine,
at least the work area, as described below.
• Depressurise compressed-air lines and hoses of the
pneumatic system.
• Carefully detach hoses. Escaping compressed air may swirl
up dust.
• Protect air connections to prevent them from getting dirty
(if necessary, using adhesive tape).
• Never mix up connections, plugs or switches. This will
inevitably result in malfunctions.
• Always work with the greatest possible level of cleanliness.
Dirt or dust in systems of the pneumatic
facility may result in malfunctions and possibly also in
significant damage to property.
Caution!
Any work on the pneumatic system must only be
carried out by authorised skilled personnel.
