Load-sensing control block SB11 | Safety instructions
Bosch Rexroth AG, RE 66177-B/2022-05-03
Escaping hydraulic fluid mist!
Risk of explosion and fire hazard, health hazard, risk of environmental pollution!
▶ Depressurize the relevant machine/system component and repair the leak.
▶ Keep open flames and ignition sources away from the control block/control
block segment.
▶ If control blocks/control block segments are located in the vicinity of ignition
sources or powerful thermal radiators, a shield must be erected to ensure
any escaping hydraulic fluid cannot be ignited, and to protect hose lines
from premature aging.
Electrical voltage!
Danger to life or risk of injury due to electric shock or property damage!
▶ Always disconnect the voltage supply to the relevant machine/system
part before installing the product and/or connecting or disconnecting
the connector.
▶ Protect the machine/system against reactivation.
Malfunction of control functions due to contamination!
Risk of injury or property damage!
Under certain circumstances, moving parts in control equipment (e.g. control spool)
can get stuck in an undefined position due to contamination (e.g. impure hydraulic
fluid, abrasion or residual dirt from components). As a result, the activated
consumer does no longer respond correctly to the operator's specifications.
▶ Comply with the prescribed cleanliness level of the hydraulic fluid in
accordance with the data sheet.
Danger caused by pressurized, leaking hydraulic fluid!
Risk of death or injury due to leaking hydraulic fluid streams! Leakage at the
control block/control block segment can lead to hydraulic fluid escaping
under high pressure.
▶ Depressurize the relevant machine/system component and repair the leak.
▶ Never attempt to block or seal the leak or hydraulic fluid jet with a cloth.
