power transmission and reduces wear on motor bearings. Use a tension gauge to measure and adjust as needed,
following the specifications provided in the machine's manual. Replace any belts or chains showing signs of fraying or
excessive stretching.

3. Monthly Preventive Maintenance
Monthly preventive maintenance is crucial for identifying and addressing potential issues before they lead to significant
problems. This more in-depth maintenance routine helps ensure the longevity and reliability of the pill pressing
machine. Let's explore the key components of monthly preventive maintenance:

Electrical System Check

Conduct a comprehensive inspection of the pill pressing machine's electrical system. This includes checking all wiring
connections for signs of wear, loose terminals, or overheating. Use a multimeter to verify proper voltage and current
readings at various points in the system. Pay special attention to control panels, motors, and safety interlocks. Address
any anomalies immediately to prevent electrical failures or safety hazards.

Hydraulic System Maintenance

For machines with hydraulic components, monthly maintenance is essential. Check hydraulic fluid levels and quality,
topping up or replacing as necessary. Inspect hydraulic hoses and fittings for leaks or signs of wear. Clean or replace
hydraulic filters according to the manufacturer's recommendations. Proper hydraulic system maintenance ensures
consistent pressure and smooth operation of the pill pressing machine.

Lubrication System Overhaul

While daily lubrication is important, a monthly overhaul of the entire lubrication system is crucial. Clean and inspect all
lubrication points, grease fittings, and oil reservoirs. Verify that automatic lubrication systems are functioning correctly
and delivering the appropriate amount of lubricant. Replace any worn grease fittings or blocked lubrication lines. This
comprehensive approach to lubrication helps minimize friction and wear on critical components.

4. Quarterly Component Replacement and Upgrades
