This helps future tracking and maintenance history.
Step 3: Describe the Problem
If the report is for corrective maintenance or breakdown, describe the problem clearly.
Example:
“The pump motor tripped on overload during operation. Operation reported abnormal noise and low discharge pressure before the trip.”
Avoid vague descriptions such as:
“Pump problem.”
A good problem description helps understand the situation.
Step 4: Record Initial Observations
Write what was found during inspection.
Examples:
- Motor overload relay was tripped
- Bearing temperature was high
- Mechanical seal leakage observed
- Cable terminal found loose
- Contactor coil not energizing
- Gearbox oil level below normal
- Abnormal vibration noticed during running
Observations should be factual and based on inspection or measurement.
Step 5: Include Measurements
Measurements make the report more professional.
Common measurements include:
- Voltage
- Current
- Insulation resistance
- Temperature
- Vibration
- Pressure
- Flow
- Oil level
- Running hours
- Alignment readings
- Torque values
Example:
Motor current:
L1: 18.2 A
L2: 18.5 A
L3: 18.1 A
Measurements help compare future readings.
Step 6: Describe the Work Performed
Write the maintenance actions clearly.
Examples:
- Isolated motor feeder and applied LOTO
- Removed coupling guard
- Inspected coupling element
- Replaced damaged bearing
- Cleaned MCC panel
- Tightened power terminals
- Replaced contactor
- Tested motor insulation resistance
- Reinstalled guard
- Conducted trial run
Use action words and write in sequence.
Step 7: Mention Spare Parts Used
Record all spare parts used during the job.
Include:
- Part name
- Part number
- Quantity
- Brand if needed
- Store issue number if available
Example:
Spare parts used:
- Mechanical seal, size 35 mm, Qty 1
- Bearing 6310-2RS, Qty 2
- Coupling rubber element, Qty 1
This helps inventory control and cost tracking.
Step 8: Record Downtime
For breakdowns or production equipment, record downtime.
Include:
- Failure time
- Maintenance start time
- Maintenance completion time
- Equipment handover time
- Total downtime
Example:
Failure reported: 08:30
Maintenance started: 08:45
Repair completed: 11:15
Equipment handed over: 11:30
Total downtime: 3 hours
Downtime data is important for maintenance KPIs.
Step 9: Identify Root Cause if Possible
If the cause is known, mention it clearly.
Examples:
- Bearing failed due to poor lubrication
- Motor tripped due to pump blockage
- Contactor failed due to burnt coil
- Cable overheated due to loose terminal
- Mechanical seal failed due to misalignment
- Compressor tripped due to blocked cooler
If the root cause is not confirmed, write:
“Root cause to be further investigated.”
Do not guess without evidence.
Step 10: Add Recommendations
Recommendations are one of the most valuable parts of a report.
Examples:
- Monitor pump vibration weekly
- Replace suction strainer during next shutdown
- Review lubrication schedule
- Keep one spare contactor in store
- Perform alignment during next planned stop
- Replace damaged cable gland
