Maintenance is a program to keep all the parts of the machine in perfect condition with minimum wear and tear.
Preventive Maintenance in Blow Room; It means to attend and check the machines regularly and systematically and defects are discovered and remedied before they cause a need for, major repair and before the wear & tear of the machine starts affecting the quality and production, | Parts to be inspected | Rating & Action taken Remarks Repaired/replaced | | Check the condition of:
