13.6 Cleaning of Machine

Qualification 1

A weekly cleaning with dry rags or diluted detergents is necessary. Cardboard boxes produce a significant quantity of dust and paper chips when processed or handled in case sealing equipment. If this dust is allowed to build up on machine components, it can cause component wear and over-heating of drive mo- tors. The dust build up is best removed from the ma- chine with a vacuum cleaner. Depending on the num- ber of cartons processed, this cleaning should be done weekly. Excessive build-up that cannot be removed by vacuuming should be removed with a damp cloth.

13.7Cleaning of Cutter Blade Qualification 2

Should tape adhesive build-up occur, carefully wipe clean with oily cloth or brush (Figure 13-1).Oil pre- vents the build-up of tape adhesive.

(See manual 2)
