13.6 Cleaning of Machine
Qualification 1
A weekly cleaning with dry rags or diluted detergents
is necessary. Cardboard boxes produce a signifi cant
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
motors. The dust build up is best removed from the
machine with a vacuum cleaner. Depending on the
number 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.
•
To reduce the risk associated with
mechanical and electrical hazards:
− Read, understand, and follow all safety and
operating instructions before operating or
servicing the case sealer.
