– The tag out alternative:
If a machine can be locked out, it must be. However, there are situations where energy
isolating devices cannot accommodate locks. In these cases, the energy isolating de-
vices must be tagged to warn employees that the machine is de-energized for servicing.
The tag 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. 2
Æ Release stored energy
(A) Turn the operating lever counterclockwise.
(B) Use the screwdriver to push the locking lug out of the operating lever.
(C) Secure the operating lever with a padlock.

The maintenance or electrical person may test the circuits by energizing the circuit for a short pe-
riod of time without voiding the lock out procedure provided. This may be done only when no other

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.
