Mistake #1: Skipping Regular Lubrication

The Problem:

Friction from unlubricated parts accelerates wear and tear, leading to premature failure of bearings, gears, and cutting blades.

The Fix:

• Follow the manufacturer's lubrication schedule.
• Use high-temperature resistant grease for moving parts.
• Check oil levels weekly in hydraulic systems.

Mistake #2: Ignoring Blade Sharpness

The Problem:

Dull blades force the machine to work harder, increasing power consumption and producing rough, uneven cuts.

The Fix:

• Inspect blades every 500,000 cycles (or as recommended).
• Use professional sharpening services—don't DIY with improper tools.
• Keep spare blades to avoid production halts.

Mistake #3: Overlooking Belt & Chain Tension

The Problem:

Loose belts/chains cause misalignment, while overtightening strains motors and bearings.

The Fix:

• Check tension monthly with a tension gauge.
• Adjust according to the machine manual's specs.
• Replace worn belts before they snap mid-production.

Mistake #4: Neglecting Dust & Debris Cleanup

The Problem:

Paper dust and adhesive residue clog mechanisms, leading to overheating and sensor errors.

The Fix:

• Blow out dust daily with compressed air.
• Deep-clean feed systems and sensors bi-weekly.
• Use anti-static cleaners for electronic components.

Mistake #5: Using Incorrect Cutting Pressure

The Problem:

Too much pressure damages dies and plates; too little causes incomplete cuts.

The Fix:

• Calibrate pressure based on material thickness.
• Test settings on scrap cardboard before full runs.
• Invest in an auto-pressure adjustment system.
