Environmental Factors; Maintenance And Repair - Bosch rexroth BS 1 Series Assembly Instructions Manual

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 specific
chemicals, such as test oil, doped oils, aggressive cleaning agents, solvents or
brake fluid.
• Avoid prolonged contact with highly reactive acidic or alkaline materials.
• Contamination can greatly increase wear – specifically from 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, waste parts, etc.). Maintenance intervals should be
significantly shortened 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

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 pneumatic pressure!
Risk of severe 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.
„
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.
• 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.
