3. Maintenance Tasks Completed

The following tasks were performed during the preventive maintenance inspection:

• Inspection of Components: Thorough check of all critical components to ensure they are functioning properly (e.g., motors, bearings, filters).

• Lubrication: Applied lubricant to moving parts to reduce friction and prevent wear.

• Cleaning: Cleaned dust, dirt, and debris from external surfaces, filters, and vents to ensure proper airflow and cooling.

• Alignment Check: Ensured proper alignment of belts, pulleys, and gears.

• Pressure Test: Conducted pressure tests on hydraulic systems to ensure there are no leaks or irregularities.

• Calibration: Calibrated sensors and gauges to ensure accurate readings.

• Electrical Systems Check: Inspected wiring, fuses, and connections for any signs of wear or damage.

• Safety Checks: Verified the functionality of safety mechanisms and emergency shutdown procedures.
