16
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 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.
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.
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.
Figure 4-1 Lubrication Points Frame

Maintenance (Continued)
WARNING Turn off electrical power supply 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 motor is overloaded. The circuit
breaker is located inside the electrical control box on
the side of machine frame just below the machine
bed.
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.

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.
Box Drive Belt Tension
The two continuously moving drive belts convey boxes through the tape applying mechanism. The box drive
belts are powered by an electric gear motor.
Tension adjustment of these belts may be required during normal operation. Belt tension must be adequate to
positively move the box through the machine and the belts 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 [7.5 lbs.]
applied at the midspan, as shown in Figure 5-1, 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.

Adjustments (Continued)
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.
Refer to Figure 5-2 and adjust belt tension as follows:
1. Remove and retain center plate and four screws.
2. Loosen, but do not remove, M10 lock nut with a 17 mm open end wrench.
3. Reset the tension on the drive belt as needed. Use M6 hex wrench and adjust the M8 socket head tension
screws in (clockwise) to increase tension or out (counterclockwise) to decrease tension. Tighten lock nut to
secure tension setting.
4. Replace center plate and secure with original screws.

Special Set-Up Procedure
WARNING Turn off electrical power and disconnect power cord from electrical supply before
beginning Special Set-Up Procedure. If power cord is not disconnected, severe injury to
personnel could result.
Changing the Tape Leg Length
(From 70 to 50 mm [2-3/4 to 2 inch])
The following changes to the case sealer frame and upper/lower taping heads will allow the taping of boxes
90 mm [3.5 inch] minimum height.
CASE SEALER FRAME
(Refer to Figure 6-1A)
1. Raise the upper head assembly by turning crank handle counterclockwise. Remove and retain the two stop
bracket screws and washers from the normal position holes "A-A".
2. Move stop bracket down and secure with original fasteners through upper holes "A" in stop bracket. Relocate
both right and left stop brackets.

Special Set-Up Procedure (Continued)
WARNING Turn off electrical power and disconnect power cord from electrical supply
before beginning Special Set-Up Procedure. If power cord is not disconnected, severe injury
to personnel could result.
TAPING HEADS
WARNING Use care when working near knives as knives are extremely sharp. If care is not
taken, severe injury to personnel could result.
1. Loosen, but do not remove, the two retaining screws that secure the upper taping head shown in
Figure 6-1B.
2. Slide the head forward and lift straight up to remove it from the case sealer.
CAUTION Taping head weighs approximately 7.2 kg [16 lbs]. Use proper body
mechanics when lifting upper or lower taping heads.
3. Lift the lower taping head, shown in Figure 6-1C, straight up to remove it from the case sealer bed.
4. Refer to Section II, "Adjustments Changing Tape Leg Length", page 13 for taping head set-up.
Box and Machine Bed Height Range Refer to Figure 6-2
Moving the outer columns up one set of mounting holed increases the maximum box size handled by the
200a case sealer and decreases the minimum machine bed height.
Note This also increases the minimum box height from 120 mm [4.75 inch] to 165 mm [6.5 inch].
To move the outer columns up one set of mounting holes:
1. Place minimum 305 mm [12 inch] high blocks at the front and rear of the upper taping head assembly as
shown in Figure 6-2A. Important Blocks (front and rear) must be same height in order to keep uppertaping head assembly parallel with machine bed/drive belts. Crank the upper taping head assembly
down until it touches these blocks.
2. Remove and retain the six screws and plain washers that fasten each column to the frame. Figure 6-2B.
3. Turn the height adjustment crank clockwise to raise the outer columns up one set of mounting holes
(100 mm [4 inch]).
WARNING Blocks and spacers must be capable of supporting the 34 Kg [75 pound] weight
of the outer columns and upper taping head assembly.
4. Install and tighten the six screws and plain washers in each column that were removed in Step 2. Crank
upper taping head assembly up and remove blocks.
If desired, the bed height can now be decreased to 520 mm [20.5 inch] by adjusting legs upward. (See
"Installation and Set-Up Machine Bed Height", Page 11.)
