Lock out / tag out (LOTO)

Before any maintenance, follow lockout/tagout procedures. Disconnect the equipment from its power source. Attach a lockout tag with your name, date, and reason.

2

Visual inspection

Inspect the equipment for visible wear, damage, or leaks. Check belts, hoses, cables, and guards. Note any issues in the maintenance log before proceeding.

3

Clean the equipment

Remove dust, debris, and residue from all accessible parts. Use approved cleaning agents only. Pay special attention to vents, filters, and moving parts.

4

Lubricate moving parts

Apply the correct lubricant to all specified points: bearings, chains, gears, and slides. Use the lubrication chart posted on the machine for types and quantities.

5

Check and replace consumables

Inspect filters, belts, blades, and other consumable parts. Replace any that show wear beyond acceptable limits. Use only manufacturer-approved replacement parts.

6

Test safety mechanisms

Verify all safety guards are secure. Test emergency stop buttons. Confirm safety interlocks function correctly. Do not skip this step.

7

Run operational test

Remove lockout tags. Power on the equipment and run a short operational test. Listen for unusual sounds. Check output quality matches specifications.

8

Log the maintenance

Record all work performed in the maintenance log: date, technician name, parts replaced, issues found, and next scheduled maintenance date.
