9.1.4 Environmental
factors
• Our products are resistant to many media that are commonly found in
manufacturing, such as water, mineral oil, grease and detergents. Contact your
Rexroth representative if you have any doubts about resistance to specifi c
chemicals, such as test oil, doped oils, aggressive cleaning agents, solvents or
brake fl uid.
• Avoid prolonged contact with highly reactive acidic or alkaline materials.
• Contamination can greatly increase wear – particularly abrasive media from the
surrounding area, such as sand and silicates, e.g. from construction as well as
machining processes in the transfer system (e.g. welding beads, pumice powder,
glass shards, chips, lost parts, etc.). Maintenance intervals should be signifi cantly
reduced under these circumstances.
• Resistance to media and contamination does not mean that functional safety is
guaranteed in every case.
– 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 effect
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.
10 Maintenance and repair
WARNING
High electrical voltage!
Risk of serious injury or death from electric shock.
Disconnect the relevant system component before performing maintenance
or repair work.
Secure the system against being unintentionally switched on again.
High pneumatic pressure!
Risk of serious injury or death.
Switch off the compressed air supply to the relevant system component before
performing any maintenance or repair work.
Secure the system against being unintentionally switched on again.
CAUTION
Hot electric motor surfaces during operation!
Risk of burns from touching hot surfaces above 65 °C.
Install appropriate separating safety guards.
Let the unit cool down at least 30 minutes before performing maintenance
and/or repair tasks.
• Only inspect and adjust continuous conveyors that are in motion or operation when
the safety guards are in place.
• Observe DIN EN ISO 13857 when you remove or replace safety guards and/or
bypass safety equipment.
• Test runs with open paneling should only be performed by a competent person using
tip switches and if there is no possibility of interference from other switching devices.
