– Liquids that thicken as they evaporate and become highly viscous or adhesive
(sticky) can lead to malfunctions.
– If they get carried onto systems with rollers, media which have a lubricating eff ect
can lead to a reduction in the drive power that is transmitted via friction.
In such instances, special care must be taken when planning the system, and the
maintenance intervals must be correspondingly shortened.
11 Maintenance and repair
High electrical voltage!
Risk of severe injury or death from electric shock.
Disconnect the relevant system component before performing any maintenance
or repair work.
Secure the system against being unintentionally switched on again.
High hydraulic/pneumatic pressure!
Risk of severe injury or death.
Switch off the hydraulic/compressed air supply to the relevant system
component before performing any maintenance or repair work.
Reduce the residual pressure in the system.
Secure the system against being unintentionally switched on again.
Hot electric motor surfaces during operation!
Risk of burns from touching hot surfaces above 65 °C.
Install appropriate guards.
Let the unit cool down for at least 30 minutes before performing maintenance
and/or repair work.
Check the component temperature before maintenance and/or repair work.
• Only inspect and adjust continuous conveyors that are in motion or operation when
the protective equipment is in place.
• Observe DIN EN ISO 13857 when you remove or replace protective equipment
and/or bypass safety equipment.
• Test runs with open paneling should only be performed by a person with
appropriate knowledge and experience using tip switches, and if there is no
possibility of interference from other switching devices.
