Safety Instructions for Work on the Cutting Device
WARNING!
Risk of injury when working near the cutter.
When working in the area of the tape cutter, move the component trolley
out of the machine and disconnect the machine from the mains supply and
the compressed air supply.
Wait until the operating pressure has dropped to 0 MPa.
Always secure the machine against unauthorized reactivation.
Do not reach into the tape cutter.

Safety Instructions on Hazardous Materials
CAUTION!
Observe the safety data sheets
Observe the applicable safety data sheet, when handling hazardous materials
(e. g. Loctite 241, ethanol).

Preparatory Work...
Purpose and Scope
Before performing any preventive maintenance work, conversion work or service
work, a procedure of locking and tagging must be followed and warning signs
must be attached if not stated otherwise. If it is not necessary to switch off the
machine, it is explicitly mentioned.
The procedure, when followed correctly, eliminates the possibility of an employee
being injured.
NOTICE!
Additional safety measures
These procedures represent the minimum lock/tag out requirements for the
machine during preventive maintenance work and service work. Any addi-
tional safeguards needed to complete work safely can be specified by facilit-
ies supervision, the safety officer, the safety committee and the health de-
partment.

Description
Whenever it becomes necessary to isolate, control and release energy, the follow-
ing procedure is to be followed.
u Notify affected employees.
u Switch off the machine and all additional devices. Carry out all normal stop-
ping procedures:
ð Press the STOP button.
ð Shut down the station computer.
ð Switch the machine off at the main switch.
u Isolate the machine from all its energy sources:
ð Shut off the compressed air supply.
ð Shut off the main power supply.
u Lock out the machine.
ð Attach a lock wherever possible (e.g. to the main power switch or the mo-
tor contactor).

u Attaching warning signs:
If a machine can be locked, it must be.
However, there are situations where energy isolating devices cannot accom-
modate locks. In 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.
u Release of stored energy:
Stored energy in the compressed air supply or electrical energy in electrolytic
capacitors must be released by appropriate means.
After switching off the machine, wait until the voltages and the compressed air
have discharged, so that work can be performed without any risk.
u 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.
u Check the working area. Authorized employees should remove all of their tools
and reinstall all safety features.
u Notify all affected employees.
u Before removing even one lock or tag, inform all workers in the affected area
that the machine is going to be restarted.
u Remove all locks/tags.
Every authorized employee must remove his own lock and shut it away.
u Turn the machine on. Make sure that authorized staff check the equipment in
operation to ensure that 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 be tagged with the "Do
Not Operate" tag to prevent inadvertent operation of the equipment during these
periods.
Responsibilities
• It shall be the responsibility of the maintenance and service personnel to make
sure this procedure is adhered to.
• It shall be the responsibility of the maintenance and service personnel's imme-
diate supervisor to instruct his personnel on this procedure.
• It shall be the responsibility of the Safety Officer with assistance from the
Safety Committee, Health Service Department, and the various managers and
vice-presidents to administer the Lock Out / Tag Out Procedure.
