– 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. 5
WARNING
To avoid damaging the revolver head, ALWAYS observe the following points when moving
the gantry: 5
– NEVER move the gantry by pushing with your hands against the revolver head.
– NEVER move the gantry by pushing with your hands against or pulling the recessed grip of
the revolver head. The revolver head may lose its settings or be damaged on account of
the high braking force of the Y-gantry drive.
– 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.
