Figure 3-4 – Air Regulator, Drive Belts
5Raising Switch, Upper Taping Head Frame
This switch, when touched by the leading
edge of a box, pneumatically raises the upper
frame to allow insertion of a box under the
upper frame, as the box moves under the
switch, releasing it, the upper frame descends
on the box and the drive belts convey the box
through the machine. When switch is
actuated by hand, the upper frame rises to its
maximum height. Released, the upper frame
descends to its rest position.
6Centering Switch, Box Drive Belts
This pneumatic switch controls the closing
(centering) of the drive belts. When switch is
activated by a box passing under it, the drive
belts close and center the box.
7Air Pressure Regulator, Box Drive Belt
Centering – Figure 3-4.
This regulator is used to adjust drive belt
centering pressure. The factory set point is 5
turns clockwise. If more pressure is needed to
center box, turn knob clockwise to desired

counterclockwise to relieve pressure.
Regulator is locked by tightening screw.
8Air Pressure Gauge, Upper Taping Head
Frame
This gauge, used in conjunction with the upper
frame air regulator, provides operator with a
reference pressure setting for various size/
weight boxes.
15
Operation (Continued)
Figure 3-5 – Air Regulator, Upper Taping Head
Frame
9Air Pressure Regulator, Upper Taping
Head Frame – Figure 3-5
Set nominally to control "down" pressure
against box. The factory set point is 15 PSIG
[1 bar]. The regulator setting is adjusted as
necessary to allow free movement of boxes
through taping heads while maintaining boxes
flaps in fully closed position. Decreasing air
pressure will increase down pressure on
boxes while increasing air pressure will
decrease down force on boxes.
For boxes which are fully packed with
products that support the top flaps, the
adjustment of this regulator is not critical since
the boxes can support the pressure of the
upper frame at a wide range of regulator
settings. However, if under-filled or fragile
boxes are sealed, this regulator is used to set
the upper frame at the minimum setting while
still maintaining adequate closure of boxes.

Figure 3-8 – Operation 8888 – Operation
Box Jam
If a box should jam or there is a need to shut the
machine off with the upper head assembly in the up
position, the E-Stop button can be pressed or the
guard door can be opened. Either function will
automatically raise the upper head assembly to its
highest position and the air pressure will be
exhausted from the belt assemblies. The box can
be removed and the tape should be checked to
insure that it is threaded properly. When the E-Stop
is pulled up or the door closed the upper head
assembly will lower to the lowest position.

Maintenance
The case sealer 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 and
air supplies 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
heads 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.
Figures 4-1 illustrates the frame points which should
be lubricated every 250 hours of operation.
Lubricate the points noted by solid arrow ( ) with
SAE #30 non-detergent oil. Lubricate the points
noted by outline arrow ( ) with multipurpose
grease.
Note – Wipe off excess oil and grease. It will
attract dust and dirt 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 case sealer 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.

Maintenance (Continued)
WARNING – Turn off electrical and air supplies 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 1.9 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,

Adjustments
WARNING – Turn air supply and electrical power off and disconnect power cord from power
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 screws 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 in]. 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 – Refer to Section II
WARNING – Use care when working near tape cut-off blades on taping heads as blades are
extremely sharp. If care if not taken, severe injury to personnel could result.
