– The Tag Out alternative:
If a machine can be locked out, it must be. However, there are situations where energy isolat-
ing devices can not 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 must be se-
curely fastened, it must be placed in a position visible to all and it may only be removed by the
person who attached it.
WARNING
To avoid damaging the collect&place head, ALWAYS observe the following points when mov-
ing the gantry:
– NEVER move the gantry by pushing with your hands against the collect&place head.
– NEVER push the gantry while the Z-axis is lowered.
– Take hold of the cast iron part of the X-axis - ideally near the X-axis toothed belt deflection
pulley - and then move the gantry.
