2. Daily Maintenance Checklist

2.1 Pre-Operation Inspection

• Check for oil leaks in hydraulic systems.

• Inspect electrical connections for wear or damage.

• Ensure mixing blades and agitators are free from hardened thermoplastic residue.

• Verify that temperature controls are functioning correctly.

2.2 Post-Operation Cleaning

• Clean the mixing tank and discharge valves to prevent material buildup.

• Flush the system with a compatible cleaning agent if switching between different thermoplastic formulations.

• Wipe down control panels and exterior surfaces to prevent dust accumulation.

3. Weekly Maintenance Procedures

3.1 Lubrication of Moving Parts

• Apply high-temperature grease to bearings, gears, and chains.

• Check hydraulic oil levels and top up if necessary.

3.2 Inspection of Heating Elements

• Examine heating coils and thermocouples for signs of wear or corrosion.

• Calibrate temperature sensors to ensure accurate readings.

3.3 Belt and Motor Check

• Inspect drive belts for tension and wear; replace if cracked or loose.

• Listen for unusual noises in motors and gearboxes, indicating potential issues.

4. Monthly Maintenance Tasks

4.1 Deep Cleaning of Mixing System

• Disassemble and manually clean mixing paddles and shafts.

• Use a high-pressure washer (if applicable) to remove stubborn deposits.

4.2 Electrical System Review
