prevent injuries to personnel or damages to the equipment. The proper safety verifications include selecting the Off
button on the main switch and carrying out the tag-out/lock-out procedure. Only the person responsible for the safety
verifications should work on the machine. At the end of the maintenance or repair operation, make sure not to leave
anyone behind, and verify that no tools or objects remain on the machine or its surroundings as they could be
violently ejected once the machine resumes its operation. Then, check the safety devices for proper function before
resuming machine operation.
