5. The case sealer can accommodate most boxes within the size range listed above However, if the
box length (in direction of seal) to box height ratio is 6 or less, then several boxes should be test run
to assure proper machine performance
DETERMINE THE BOX LIMITATIONS BY COMPLETING THIS FORMULA:
BOX LENGTH IN DIRECTION OF SEAL SHOULD BE GREATER THAN .
BOX HEIGHT
Any box ratio approaching this limitation should be test run to assure performance

11
Receiving And Handling
After the machine has been uncrated, examine the
case sealer for damage that might have occurred
during transit If damage is evident, file a damage
claim immediately with the transportation company
and also notify your 3M Representative
Machine Set-Up
Note  A tool kit consisting of metric open
end and hex socket wrenches is provided
with the machine These tools should be
adequate to set-up the machine, however,
other tools supplied by the customer will be
required for machine maintenance
PACKAGING AND SEPARATE PARTS
1 Follow "Unpacking Instructions" label attached
to corrugated packing cover
2 Height adjustment crank is shipped in upside
down position Remove the crank and install
right side up as shown in Figure 2-1A
Note: Height adjustment crank can be
installed on either column for operator
convenience.
3 Cut and remove tie down straps that secure
upper assembly to machine bed on each side of
machine at vertical columns
4 Crank the upper assembly up and remove the
2 x 4 wood frame that supports the flap folder
assembly
5 Secure pneumatic controls to side frame as
shown in Figure 2-1B
6 Install the tape drum bracket on the upper taping
head as shown in Figure 2-1C
7 Hold taping head BUFFING ROLLER and cut
and remove cable tie that holds applying/buffing
arms retracted on both taping heads See
Figure 2-1D Allow buffing/applying arms to
extend slowly Also cut and remove cable ties
that secure lower taping head in place
Installation and Set-Up
Important  Read "Warnings", on page 20,
before attempting to set-up the case sealer
for operation
The following instructions are presented in the order
recommended for setting up and installing the case
sealer, as well as for learning the operating
functions and adjustments Following them step
by step will result in your thorough understanding of
the machine and an installation in your production
line that best utilizes the many features built into the
case sealer Refer to Figure 3-1 and 3-2 to identify
the various components of the case sealer
It is recommended that the case sealer be set-up
and operated with product before placing it in the
production line This approach will allow your
thorough review and familiarization with the case
sealer before subjecting it and operating personnel
to a production situation where time for set-up,
adjustments, and operator training usually becomes
limited
For future reference, record machine serial number
on front cover of this manual in the space provided
WARNING  Follow this step
carefully as spring pressure is
applied to applying and buffing arms when
cable tie is removed. Keep hands/fingers
away from tape cut-off knife under orange
knife guard. Knife is extremely sharp and
can cause severe injury.
8 Push buffing roller into head to check for free,
smooth action of upper and lower taping heads
WARNING  Keep hands/fingers
away from tape cut-off knife under
orange knife guard. Knife is extremely
sharp and can cause severe injury.

12
9 Remove fasteners that secure case sealer legs
to pallet
Use appropriate material handling equipment to
remove the machine from the pallet and move it
into position
Whenever the machine is lifted with a fork truck,
insure that the forks span completely across the
machine frame and do not contact any wiring or
mechanism under the machine frame Remove
lower taping head by lifting head straight up
out of machine bed. Also make certain to have
one side of the fork on each side of the vertical
column and electrical control box as shown in
Figure 2-3
CAUTION  Machine weighs
approximately 250 kg [545 lbs]
uncrated.
Installation and Set-Up (Continued)
Figure 2-1  Machine Set-Up
Refer to Figure 2-2A and set the machine bed
height as follows:
a Use appropriate material handling
equipment and blocking techniques to raise
the machine frame to allow adequate leg
adjustment
b Loosen, but do not remove, two M8 x 16
socket head screws in one leg (use M6 hex
wrench) Adjust the leg length for the
desired machine bed height Retighten the
two screws to secure the leg Adjust all four
legs equally
10 Adjust machine bed height The case sealer is
equipped with four adjustable legs that are
located at the corners of the machine frame
The legs can be adjusted to obtain different
machine bed heights from 585 mm [23 inch]
minimum to 715 mm [28-1/8 inch] maximum

13
Installation and Set-Up (Continued)
Note  Case sealer must be installed level, it is
not designed to convey boxes uphill
Figure 2-2  Machine Bed Height Adjustment and Lower Tape Drum Bracket
Contact your 3M Representative for assistance
in selecting conveyor requirements and speed
that will comply with your box capability
11 The lower taping head tape drum bracket has
two mounting positions to allow maximum tape
roll capacity
For machine bed height 650 mm [25 63 inch]
and above, use mounting position shown in
Figure 2-2B
For machine bed heights below 585 - 650 mm
[23 00 - 25 63 inch], use mounting position
shown in Figure 2-2C
Note  A minimum spacing, equal to 405 mm
[16 inch] between boxes at a maximum
conveyor speed of 0 30 m/s [60 F P M ] must
be maintained for boxes entering the case
sealer
Refer to Figure 2-3 for suggested conveyor
types that can be used in production line
12 Install case sealer in production line

14
Installation and Set-Up (Continued)
WARNING  Use care when working
with compressed air.
The case sealer requires a 5 2 bar gauge
pressure [75 psig] 42 litre/min, @21°C, 1 01 bar
[1 5 SCFM] compressed air supply at 27 boxes
per minute As shown in Figure 2-4, an on/off
valve, pressure regulator, and filter are provided
to service the air supply
a Read and remove safety tag from pneumatic
"On/Off" valve Make sure the valve is in the
"EXH" (off) position
b Connect the main air supply line to the inlet
side of the on/off valve using the barbed
fitting and hose clamp provided See Figure
2-4 The customer supplied air hose
(8 mm [5/16 inch] ID) must be clamped
tightly to the barbed fitting
If another type of connector is desired, the
barbed fitting can be removed and replaced
with the desired 1/4-18 NPT threaded
connector
Always turn the air valve "off" when the air
supply line is being connected or
disconnected

Installation and Set-Up (Continued)
TAPING HEADS
Tape Width  the taping heads have been pre-set to
accommodate 48 mm [2 inch] wide tape rolls To
apply 36 mm [1 5 inch] or 42 mm [1 75 inch] wide
tapes, refer to Section II, "Adjustments  Tape Web
Alignment", page 11
Tape Leg Length  taping heads are pre-set to
apply 70 mm [2 75 inch] long tape legs To change
tape legs to 50 mm [2 0 inch], refer to Section II,
"Adjustments  Changing Tape Leg Length",
page 13
BOX SIZE CAPACITY OF CASE SEALER
At its factory setting, the case sealer handles
box sizes up to 508 mm [20 inch] maximum
height If larger capacity is needed, the machine
can be adjusted to accommodate boxes up to
615 mm [24 25 inch] high Refer to "Special
Set-Up Procedure  Outer Column Re-
Positioning", page 34 Note  Adjusting
machine to accommodate 15 mm
24.25 inch] high boxes also increases
minimum box size to 205 mm [8.0 inch].
INITIAL START-UP OF CASE SEALER
After completing the "Installation and Set-Up"
procedure, continue through "Operation" for tape
loading and start-up to be sure case sealer is
properly adjusted to run boxes
WARNING  To prevent shock and
fire hazard: Position extension cord
where it will be out of the way of foot or
vehicle traffic. Extension cord is only for
temporary use  do not use for a
permanent installation.
Note  Machines outside the U S may be
equipped with 220/240 Volt, 50 Hz systems
or other electrical requirements compatible
with local practice
14 Electrical Connection
The electrical control box (mounted on the lower
right side of the machine frame), contains the
pre-set circuit breaker The box can be
relocated to the other side of the machine if
desired A standard three conductor power cord
with plug is provided at the back of the electrical
control box for 115 V , 60 Hz, 2 8 Amp electrical
service The receptacle providing this service
shall be properly grounded Before the power
cord is plugged into 115 Volt, 60 Hz outlet make
sure that all packaging materials and tools are
removed from the machine Do not plug
electrical cord into outlet until ready to run
machine.
Use of an extension cord is not recommended
However, if one is needed for temporary use, it
must have a wire size of 1 5 mm diameter
[AWG 16 ], have a maximum length of 30 5 m
[100 ft], and must be properly grounded
