these cases, the energy isolating devices must be tagged to warn employees that the
machine is de-energized for servicing. The tag or label must be securely fastened, it must be
placed in a position visible to all and it may only be removed by the person who attached it.

► Release of stored energy:
Energy stored as compressed air in the compressed air supply or electrical energy stored in
electrolytic capacitors must be released by appropriate means.
After switching off the machine, wait until the voltages have discharged and the compressed
air has released, so that work can be performed without any risk.
DANGER
Checking for absence of voltage!
► Before you start working, check the power supply for absence of voltage and observe
the waiting times!
► Testing the lock out:
The lock can be easily tested by pressing the START button.
The following steps must be taken to restore the machine to operation.
► Check the workspace. Authorized employees should remove all of their tools and reinstall all
safety features.
► Notify all affected employees.
► Before removing even one lock or tag, inform all workers in the affected area that the machine
is going to be restarted.
► Remove all locks/tags.
Every authorized employee must remove his own lock and shut it away.
► Switch on the machine. Make sure that authorized staff check the equipment in operation to
ensure that all repairs were performed correctly.
Testing
Service personnel may test circuits by energizing them briefly without suspending the Lock Out /
Tag Out Procedure. This may only be done when no other work is being performed by any other
person on the equipment being tested.
It is extremely important that all remote START switches are tagged with the "Do Not Operate" tag
to prevent inadvertent operation of the equipment during these periods.
