VPI Weekly Inspection

What maintenance should you be performing on your bagger on a weekly basis?

Weekly inspection of your machine will help prevent mechanical malfunctions. When inspecting your machine, you should look for component wear and check for proper component operation. This section indicates which components should be inspected and what to look for during the inspection.

Knife Actuation

Check that the cutting knife extends and retracts smoothly. You can screw a 6mm bolt into the end of the extend/retract air cylinder to manually actuate it.

Examine some of the bags from the last production run to see if the knife is cutting cleanly through the packaging material. If it is not, replace it (refer to section 6.0, Working with Components, Replacing the Cutting and Perforation Knives).

Danger: Be sure that you hands are clear of the cutting area when extending the cutting knife, and, wear protective gloves.
