CAUTION
Risk of injury from compressed air!
Risk of injury when disconnecting the compressed air lines.
► NEVER disconnect compressed air lines while they are still pressurized.
CAUTION
Prolonged interruptions to the compressed air supply can cause damage.
When the machine is switched on, do not use the shutoff valve to interrupt the compressed air
supply for more than 30 minutes.
► If you need to shut off the compressed air system for longer, in order to carry out mainte-
nance or servicing work, you must switch the machine off at the main switch and disconnect
it from the power supply.
WARNING
Risk of injury when working near the cutter.
If you wish to work on the tape cutter, disconnect the machine from the mains supply and com-
pressed air supply.
► Wait until the operating pressure has dropped to 0 MPa.
► Always secure the machine against unauthorized reactivation.
CAUTION
Risk of injury when performing service work on the cutter.
Never support the cutter on your body, e.g., on your knees or thighs. Do not place your feet
under the cutter.
► Wear appropriately thick protective gloves.
► When removing/fitting the cutter, hold it only on the left and right, on the outside.
CAUTION
Moving the gantry can damage the placement head.
When moving the gantry, observe the following:
► NEVER move the gantry by pushing with your hands against the placement head.
► NEVER push the gantry while the Z axis is lowered.

1.2 Preparatory Work...
Purpose and scope
Before performing any preventive maintenance work or service work, a procedure of locking and tagging
must be followed and warning signs must be attached. The procedure, when followed correctly, elimi-
nates the possibility of an employee being injured.
Description
Whenever it becomes necessary to isolate, control and release energy, the following procedure is to be
followed.
► Notify affected employees.
► Switch off the machine and all additional devices. Carry out all normal stopping procedures:
⇨ Press the STOP button.
⇨ Shut down the station computer.
⇨ Switch the machine off at the main switch.
► Isolate the machine from all its energy sources:
⇨ Shut off the compressed air supply.
⇨ Shut off the main power supply.
► Lock out the machine.
⇨ Attach a lock wherever possible (e.g. to the main power switch or the motor contactor).
NOTICE
Additional safety measures
These procedures represent the minimum lock/tag out requirements for the machine during
preventive maintenance work and service work. Any additional safeguards needed to complete
work safely can be specified by facilities supervision, the safety officer, the safety committee
and the health department.
Example: attaching a padlock to the motor contactor
► Turn the operating lever (1) counterclockwise.
► Use the screwdriver to push the locking lug (2) out of
the operating lever (1).
► Secure the operating lever with a padlock (3).

► Alternative: attaching warning signs
If a machine can be locked, it must be. However, there are situations where energy isolating devices
cannot accommodate 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 fas-
tened, 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:
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.
► 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 working area. 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 locks/tags
► Every authorized employee must remove his own lock and shut it away.
► 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 pre-
vent 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 immediate supervisor to in-
struct 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.
