Maintenance
The case sealer has been designed for long, trouble
free service. The machine will perform best when it
receives routine maintenance and cleaning.
Machine components that fail or wear excessively
should be promptly repaired or replaced to prevent
damage to other portions of the machine or to the
product.
WARNING – Turn off electrical
power supply and disconnect power
cord from electrical supply before
beginning maintenance. If electrical
power is not disconnected, severe injury
to personnel could result.
Note – Never attempt to remove dirt from the
machine by blowing it out with compressed air. This
can cause the dirt to be blown inside the motor and
onto sliding surfaces which may cause premature
equipment wear. Never wash down or subject
equipment to conditions causing moisture
condensation on components. Serious equipment
damage could result.
TAPING HEAD LUBRICATION – See Section II,
"Maintenance – Lubrication", page 10.
Lubrication
Most of the machine bearings, including the drive
motor, are permanently lubricated and sealed and
do not require additional lubricant.
Figure 4-1 illustrates the machine points that do
require lubrication every 250 hours of operation.
Lubricate the points indicated by arrows ( ) with
a small amount of multi-purpose grease.
Note – Wipe off excess oil and grease. It will attract
dust which can cause premature equipment wear
and jamming. Take care that oil and grease are not
left on the surface of rollers around which tape is
threaded, as it can contaminate the tape's adhesive.
Regular slotted containers produce a great deal of
dust and paper chips when processed or handled in
equipment. If this dust is allowed to build-up on
machine components, it can cause component wear
and overheating of drive motor. The dust build-up
can best be removed from the machine by a shop
vacuum. Depending on the number and type of
boxes sealed in the case sealer, this cleaning should
be done approximately once per month. If the boxes
sealed are dirty, or if the environment in which the
machine operates is dusty, cleaning on a more
frequent basis may be necessary. Excessive dirt
build-up that cannot be removed by vacuuming
should be wiped off with a damp cloth.
