13-MAINTENANCE AND REPAIRS (continued)
13.6 Cleaning of Machine
Qualification / Skill 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 overheating of drive
motors. The dust buildup is best removed from the
machine with a vacuum cleaner. Depending on the
number of cartons processed, this cleaning should
be done weekly. Excessive buildup that cannot be
removed by vacuuming should be removed with
a damp cloth.
13.7 Cleaning of Cutter Blade
Qualification / Skill 2
- Should tape adhesive buildup occur, carefully
wipe clean with oily cloth or brush. Oil prevents
the buildup of tape adhesive (Figure 13-1).
- Worn or damaged cutter blades must be replaced
promptly in order to guarantee a perfect cut of the
tape. Lubricate the felt pad on the blade guard
without saturating it.

13.8 Lubrication

Most of the machine bearings, including the drive
motor, are permanently lubricated and sealed and
do not require additional lubricant.
Figures illustrate the taping head and frame points
which should be lubricated every 250 hours of
operation. Lubricate the rotating and pivoting points
noted by the arrows with a synthetic lubricant. At the
same time, a small amount of Silicone should be
applied to the end of each spring where the loop is
secured to an eyelet
(Figures 13-2).
Note: Wipe off excess Silicone. It will attract
dust which can cause premature equipment
wear and jamming. Take care that Silicone
is not left on the surface of rollers around
which tape is threaded, as it can contaminate
the tape's adhesive.

To reduce the risk associated with sharp
blade hazards:
−
Keep hands and fi ngers away from tape
