Autonomous Maintenance (AM) is dedicated to Operators. It is a great idea of TPM strategy to make operators directly involved in improving machines availability and enhancing TPM overall efficiency. Since “Total” means the involvement of all and everybody in a continuous improvement and waste elimination (MUDA), the role of Maintenance evolves from reactive to preventive, and most of the daily inspections are shifted to operators. In short, a new definition of the roles in Maintenance means that technicians and engineers focus on preventive & predictive maintenance, while production operators do the autonomous maintenance. Technicians are obliged to deal with breakdowns and restore the production, while operators are involved in eliminating micro-stoppages. Since both parties know well their machinery and equipment, the list of AM activities should arise from their common experience. Finally, operators need to be well trained and then they can be provided with checklists to perform the tasks assigned. This module of LEAN Academy will tell us that there are two levels of AM: level 1 – routine checks, and level 2 – specific actions e.g. lubrication, replacement of parts, cleaning etc.

What is TPM?
Total Productive Maintenance (TPM) is a method to
achieve maximum equipment effectiveness through
employee involvement
Management + Operators + Maintenance

6. 6
TPM Principles
 Increase Overall Equipment Effectiveness (OEE)
 Upgrade operations and maintenance skills
 Employee involvement through small group activities
 A fact-based approach to continuous improvement

TPM is a paradigm shift 1
Old Attitude TPM Attitude
I use You maintain &

Operator Maintenance
We maintain !

8. Old Philosophy New philosophy
 I operate, you fix, he designs. . .
 Quality is costly. . .
 Supervisors & engineers are
experts. . .
 Defects, speed losses & unplanned
downtime are inevitable…
 Inventory is useful
We are all responsible for our
equipment.
Quality is free.
Operators/Maintenance are
experts too.
Zero defects, zero speed losses,
zero unplanned downtime.
Inventory is costly.

What is Autonomous Maintenance?
 Autonomous Maintenance is maintenance performed by
operators
 Basic maintenance that can be easily performed on a daily
basis, e.g. inspection, cleaning, lubrication, etc.
 Learning about the equipment to understand how it works
and be able to spot signs of trouble
 An employee engagement program as part of the Lean/TPM
initiative

 Use of audits
 Determine full implementation of each step
 Provide feedback on strengths and weaknesses
 Clarify what needs to be achieved and best way to do it

Natural & Forced Deterioration
 Deterioration is what leads equipment to break down or
generate defective parts
 Natural Deterioration – Normal wear caused by parts rubbing
against one another
 Forced Deterioration – Deterioration that happens sooner
than it would naturally. Usually caused by our failure to do
something we ought to. Examples:
 Not keeping parts clean and lubricated
 Ignoring excessive loads in moving parts

Activity Board
 Activity board is a visual tool to guide teams to action
 Basic elements of problem solving:
1. What are we going to do? (Theme)
2. Why are we going to do it? (Vision)
3. How far are we going to go? (Targets)
4. How are we going to do it? (Method)
5. What is the sequence and timing of actions? (Schedule)
6. Who does what? ( Roles)
7. What results do we expect? (Assessment)

What is One-Point Lesson?
 One-point lesson is a 5-10 min self-study lesson drawn up by
team members
 Lesson covers a single aspect of equipment or machine
structure, functioning, cleaning, lubrication, inspection or
tightening method
 Is a highly effective tool because it is short and focused on a
topic

24. 24
One-Point Lessons as a Cascading Training Tool
Team members are responsible
for training each other
Teaching promotes effective
leadership and accountability
One-point lessons – a teaching
tool that is short and to the point
Follow up to see what has been
taught is practiced

25. 25
Types of One-Point Lessons
1. Basic Knowledge
Lesson
2. Examples of Problems 3. Examples of
Improvement
• Training tool designed to
fill in knowledge gaps
• To ensure team members
have consistent
knowledge they need for
daily production and
TPM activities
• Lessons are focused on
equipment subsystems,
safety points, or basic
operating information
• Based on problems that
have already occurred,
these lessons are
designed to
communicate knowledge
or skills to help operators
prevent similar problems
from happening in the
future
• To ensure that successful
improvement ideas are
used widely, these
lessons present what
needs to be done to
prevent or correct
equipment abnormalities
• It describes the
approaches, actions, and
results of specific
improvement projects

7 Steps of Autonomous Maintenance
1. Clean and inspect
2. Eliminate problem sources and inaccessible areas
3. Draw up cleaning and lubricating standards
4. Conduct general inspections
5. Conduct autonomous inspections
6. Standardize through visual workplace management
7. Implement autonomous equipment management
Source: Autonomous Maintenance for Operators by JIPM

29. 29
Step 1 – Clean and inspect
 Eliminate all dirt and grime on the machine, lubricate and
tighten bolts
 Find and correct problems
 Implement the Activity Board and the 4Ms
 Address operators’ questions during education process
 Develop countermeasures to mis-operations as early as
possible
Eliminate all sources of dirt and grime on the machine,
lubricate, tighten bolts, and find and correct problems

30. 30
Initial Cleaning is the Foundation of
Autonomous Maintenance
 Cleaning is inspection
 Inspection is finding problems
 Problems demand restoration to original proper conditions
and improvement to prevent recurrence

31. 31
When You Find a Problem, Tag It!
 Attach a tag to each problem you expose so that it won’t be
forgotten
 Fix problems as soon as possible and remove the tag
 Draw up plans for resolving problems that can’t be addressed
immediately

32. 32
Step 2 – Eliminate problem sources and
inaccessible areas
 Correct sources of dirt and grime
 Prevent spattering
 Improve accessibility for cleaning and lubrication
 Establish time targets for cleaning
 Establish tentative standards
Correct sources of dirt and grime; prevent spattering and
improve accessibility for cleaning and lubrication. Shorten the
time it takes to clean and lubricate.

33. 33
Step 4 – Conduct general inspections
 How to develop general inspection
 Overall inspection procedures and sub-steps
 Preparing inspection education
 Conducting overall inspection education
 Set tentative inspecting standards
 Restore and improve equipment

34.  Lubrication
• Color-coded marks to indicate
oil inlets
• Oil level and supply interval
labels
• Indication of upper and lower
oil level limits
• Indication of oil consumption
per standard time unit
• Color-coding on oil cans to
indicate oil types
 Equipment elements
• “Inspected” marks and math
marks
• Color-coding (blue) on bolts
reserved for adjustment by
maintenance personnel only
• Color-coding (yellow) on holes
that do not require bolts
Suggestions for Visual Controls

35. 35
Example: Use of Match Marks
Match marks are placed
on bolts and nuts so that
operator can easily detect
if bolts have been loosen
due to excessive
vibrations. These are
being placed on critical
bolts after each bolt had
received their correct
torque.

36. 36
Step 5 – Conduct autonomous inspections
 Prepare standard check sheets for autonomous inspections
 Define autonomous chart / schedule for each operator
 Carry out the inspections
 Use new methods of cleaning and lubricating
Prepare standard worksheets for autonomous
inspections. Carry out the inspections.

37. 37
Checklist for Daily Operator PM
 1. Check coolant level through clear Plexiglas
 2. Check heat exchanger fans
(strings should be moving)
 3. Check servo drive fans
(string should be moving)
 4. Check heat exchanger air filter

 5. Check servo drive air filter
(change when dark)
 6. Check way lube reservoir

How to Sustain AM?
 Active leadership for TPM initiative
 AM is owned by Production department and supported by
Maintenance department
 Proper operator training, education and skills certification
 The time required for cleaning and lubrication must be
included in the daily schedule
 Supervisors need to ensure that AM activities are performed
