Preventive Maintenance

A properly maintained Prawnto can provide years of dependable service. Learning how your machine normally sounds and operates helps you recognize changes before they become larger problems.

Important — Safety First: Always turn OFF and unplug your Prawnto before removing covers, inspecting internal components, or making maintenance adjustments. Reinstall all covers and safety guards securely before operating your machine.

1. What You Need To Know

Become Familiar With Your Prawnto: A properly operating Prawnto has a familiar running sound. Encourage operators to recognize that sound and report unusual squealing, chattering, knocking, or changes in operation. Unusual noises may indicate that lubrication, alignment, or mechanical components need attention.



Regular Inspections Matter: Periodically inspect the condition and alignment of the Feeder Discs, Roller Discs, cutting blade, belt, shaft collars, and pulleys. Proper maintenance helps maintain consistent shrimp cuts and reduces unexpected interruptions.

2. Preventive Maintenance Checks

  • Feeder Discs & Roller Discs: Make sure the disc contact points are properly lubricated with Prawnto Oil #100. Check the discs for wear and confirm that their spacing and alignment remain correct.
  • Pulleys & Set Screws: Check that the pulleys are secured to their shafts and their set screws are tight. Loose pulleys can affect operation and alignment.
  • Shaft Collars & Bearings: Check the shaft collars for looseness and unwanted side-to-side shaft movement. Shaft collars should be positioned properly against the nylon washers and bearings to prevent unwanted movement while allowing proper rotation.
  • Cutting Blade Alignment: Periodically inspect the blade's position between Feeder Discs #313. A properly centered blade is essential for consistent cutting and vein removal. If the blade is off-center, follow the Prawnto Alignment & Maintenance instructions before returning the machine to production.

3. Tune-Up Kit #539 — Replacing Worn Parts

The Prawnto Tune-Up Kit #539 provides replacement components that experience wear during regular shrimp processing. Replacement frequency depends on production volume, operating conditions, and the condition of the components.



Never Be Without Essential Replacement Parts — Team Prawnto Recurring Parts Program: Keep Tune-Up Kit #539 available when your operation needs it. Ask Team Prawnto about establishing a replacement-parts reordering schedule based on your production volume.
