18
Page 24
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.
Cleaning
Note – Never attempt to remove dirt from
taping head 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.
Figure 4-1 illustrates the frame points which should
be lubricated every 250 hours of operation.
Lubricate the rotating and pivoting points, noted by
the arrows, ( ) with SAE #30 non-detergent oil.
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.
Taping Head Lubrication – See Section II,
"Maintenance – Lubrication", page 10.
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.
Lubrication
Like most other equipment, the taping head must be
properly lubricated to insure long, trouble free
service. Most of the machine bearings are
permanently lubricated and sealed and do not need
to be greased. The drive motor is also permanently
lubricated and does not require additional
lubrication.

Page 25
Maintenance (Continued)
WARNING – Turn off electrical power and disconnect power cord from electrical supply
before beginning maintenance. If power cord is not disconnected, severe injury to personnel
could result.
Circuit Breaker
The case sealer is equipped with a circuit breaker
which trips if the motors are overloaded. Located
inside the electrical enclosure on the side of the
machine frame just below the machine bed, the
circuit breaker has been pre-set at 2.2 amps and
requires no further maintenance.
WARNING – The following
procedure must be performed by
trained service personnel because of the
high voltage electrical hazard within the
control box.
If circuit is overloaded and circuit breaker trips,
unplug machine from electrical power:
1. Determine cause of overload and correct.

Page 27
Adjustments
WARNING – Turn off electrical power supply and disconnect power cord from electrical supply
before beginning adjustments. If power cord is not disconnected, severe injury to personnel
could result.
Drive Belt Tension
Tension adjustment of the drive belts may be required during normal operation. Belt tension must be adequate to
positively move the box through the machine and they should run fully on the surface of the pulleys at each end of
the frame. The idler pulleys on the infeed end are adjusted in or out to provide proper belt tension. Each belt is
adjusted separately.
Belt tension is obtained by tightening the adjustment screw so that a moderate pulling force of 3.5 kg [7 lbs]
applied at the midspan, as shown in Figure 4-4, will deflect the belt 25 mm [1 inch]. This will assure positive
contact between the belt and the drive pulley on the discharge end of the taping head.
To adjust belts, see "Maintenance – Drive Belts", page 20.
Taping Head Adjustments
WARNING – Use care when working near tape cut-off knife on taping head as knife is
extremely sharp. If care is not taken, severe injury to personnel could result.
