Ensure complete power-off and all moving parts have stopped. Engage safety locks/brakes to prevent accidental activation during replacement. Verify machine stabilization before accessing the film compartment.

Thoroughly examine new film for tears, punctures, or edge defects. Confirm specifications (width, thickness, adhesion) match machine requirements. Reject damaged or incompatible film to prevent operational failures.

Handle film rolls carefully to prevent surface damage. Align precisely with feeding mechanism, avoiding over-tightening of clamps. Maintain proper tension settings for smooth unwinding during operation.

Clean all components (rollers, guides, cutters) removing debris and old film remnants. Use soft brushes/cloths to prevent scratching surfaces. Ensure unobstructed film path for consistent wrapping performance.

Conduct slow-speed test run observing film feeding, wrapping, and cutting. Verify proper adhesion and tension. Make necessary adjustments before resuming full harvesting operations to prevent field failures.
