Please read section 1.6 (Requirements & instructions for installation,
maintenance and operating staff) before starting maintenance.
WARNING
Risk of injury due to system maintenance by untrained personnel
This can result in serious injury.
► The system must only be maintained by trained personnel who have read and
understood the operating instructions.
WARNING
Risk of injury from worn, unmaintained parts
Worn and unmaintained parts can cause damage, resulting in failure of the
vacuum tube lifter and potentially causing severe injury.
► Observe the operating, maintenance and servicing requirements specified in
these operating instructions.
9.2 Checking safety features
A non-return valve is built into the rotary union of the vacuum tube lifter
J
UMBO
.
This prevents the working vacuum from falling too quickly in the event of a power failure.
Check this non-return valve at the start of every shift (if the unit is not operated continuously) or once a
week (if operated continuously). Be sure to remain outside of the danger zone during the check.
Rectify any faults before starting operations with the vacuum tube lifter
J
UMBO
. If faults occur during
operation, switch off the vacuum tube lifter
J
UMBO
immediately and rectify the faults.
