9 SEAL CONTROL
A regular control of the seal is necessary. The seal can be checked visually and the person controlling can
easily judge the quality of the seal. When checking the seal the following illustrations must be compared.
Correct seal
A correct seal must be conform to the illustration. This means that the depth with which the upper strap hooks
into the lower one must be 1 - 1.5 mm in min. and 2 mm in max.. The upper strap must be sheared clean and
the cutter must not leave scratch marks on the lower strap.
Incorrect seal (the sealing mechanism is adjusted too high)
This stamped seal is not deep enough and the upper strap is not sheared.The tensile strength of this seal is
not sufficient and the strapping must be taken away from the package. The tool must be readjusted immediately
(see SEAL ADJUSTMENT ).
Incorrect seal (the sealing mechanism is adjusted too low)
This stamped seal is too deep and the lower strap is scratched by the cutter. Although the tensile strength of
this seal is sufficient the strapping must be taken away from the package because of the scratched lower
strap. The tool must be readjusted immediately (see SEAL ADJUSTMENT).
WWW.TRADITIONALTOOL.COM
For Parts & Service 1-877-862-6699

10 a383man.en
10 SEAL ADJUSTMENT
The depth of the sealing mechanism and the cutter can be steplessly adjusted by turning the adjusting screw
with a screw driver.
Sealing depth is excessive
Turn adjusting screw clockwise. A turn
of 90°equals a stroke correction of
0.25 mm/.010".
Sealing depth is insufficient
Turn adjusting screw counter-
clockwise. A turn of 90°equals a
stroke correction of 0.25 mm/.010".
If low gauge and soft straps are used
the sealless joint is not always
properly formed (the straps do not
interlock properly). In order to avoid
inproper interlocking the timing of the
interlock can be influenced by the
adjustment of a throttle on the control
valve body.
Under normal conditions the holding air
throttle is screwed flush into the outside
of the control valve body. If the straps
do not interlock properly (one or two
notches do not interlock at all) the
throttle has to be turned in a
clockwise direction.
Attention!
Adjust holding air throttle in such a way
that no tension marks on the
bottom of the seal caused by the punch
will be noticed. If marks are noticed the
punch might wear
prematurely.

11 MAINTENANCE
Depending on the working conditions and the use of the tool the following maintenance has to be made
periodically:
11.1 Air-unit
• Checking the air pressure daily.
• Checking the oil-level daily.
• The water separator must be emptied before it is full (unless automatic).
• The filter has to be cleaned following the instructions of the manufacturer of the air- unit.
Oil for the air-unit
HL or CL ISO-VG 10
11.2 Oil level in the pressure intensifier
Control
A proper operation of the tool is only warranted if there is the correct amount of oil in the pressure intensifier.
The position of the piston in its idle position reveals whether there is enough, too much or not enough oil in the
pressure intensifier. A flawless operation of the tool is guaranteed only if the amount of oil in the pressure
intensifier is correct!
If there is too much oil in the pressure intensifier the position of the piston in its idle position is lower than the
lower edge of the body (visible when flapper is open). As a result of this faulty position of the piston there is
not enough space for the straps and the seal joint resp; it is difficult or impossible to insert the straps into the
tool and to remove them from the tool resp..
If there is not enough oil in the pressure intensifier the position of the piston in its idle position is higher than
the lower edge of the body (visible when the flapper is open). As a result of this faulty position of the piston
there is a risk that the stroke of the piston during the sealing action is too short and consequently the seal joint
is not formed properly and the upper strap is not cut entirely in spite of the correct adjustment of the adjusting
screw resp..
Oil for the pressure intensifier in the tool
SAE 10W-20 (for refilling)
Refilling of oil into the pressure intensifier
• Turn tool with flapper in an upward position. Remove sealing screw.
• Introduce wrench (N7.3250) into boring with valve handle being parallel to the toggle, turn toggle by 90°
(thus the sealing piston is moved into its correct position).
• Turn back the wrench and remove it.
• Fill in oil of type SAE 10W-20 and let escape air bubbles. Screw in sealing screw again and tighten it.
• Check the position of the sealing piston as per afore mentioned instructions.

11.3 Cleaning
If impact of dirt and dust is considerable and if painted straps are used the feed wheel must be cleaned
regularly. Normally it is sufficient to blow out this part by using an air gun.
11.4 Lubrication
The gear is filled with MOLYKOTE BR 2 PLUS. Use the same type of grease after repairs.
When being exchanged, all valve parts and other movable parts have to be greased with grease of type
Mobilux EP2 or with any equivalent product.
12 Exchange of wearing parts
12.1 Exchange of punch and die halves
If in spite of a correct adjustment of the adjusting screw it is no longer possible to make a proper seal (see
seal control) the base plate must be removed and the wear of the punch and the die halves must be
examined.
If the cutting edges are destroyed or worn heavily (attention! the cutting edges of new punches and dies are
also rounded slightly) the corresponding parts must be replaced.
Important!
Make sure that the mounting surfaces are completely free from dirt before the new parts are installed.
After assembling the base plate, the base plate screws must be tightened using a torque wrench with
a torque of 90 Nm.
The screws N1.1323 und N1.1806 have to be secured with Loctite 222.

14 Functional characteristics
Idle position
Because of the connection of the tool to the compressed air-net (connection P) compressed air flows through
flapper valve 3 to the flapper cylinder 19 and rocker cylinder 17.
As a result of this air-flow, the closing force of the spring of the flapper cylinder 19 is supported by compres-
sed air on the one hand (flapper closed) and the feed-wheel is lowered to the gripper on the other hand.
The closed flapper 27 holds open flapper security valve 4. Flapper security valve 4 opens the line to sealing
valve 5 and motor valve 6 (both closed) and also to pilot valve 8, throttle 10, diaphragm 13 and holding air
valve 14.
As a result, holding air valve 14 is kept closed. Compressed air is also conducted to the holding air throttle 11
directly from the main connection and stops at the closed holding air valve 14.
Inserting the strap
To insert the strap, the flapper valve lever 23 of the flapper valve 3 is lifted. The valve switches, the flapper
cylinder 19 opens the flapper 27 and the rocker cylinder 17 lifts the feed wheel.
After inserting the strap, the flapper valve lever 23 is released again; flapper valve 3 and both cylinders 17 and
19 stay again in their idle position. The throttles 1, 2, 16 and 18 avoid jerking motions.
Tensioning
By pressing down the motor valve lever 24 the motor valve 6 is commuted and catches in an open position.
Compressed air now flows from connection P through the flapper security valve 4 and motor valve 6, the
adjustable throttle valve 7 and through the non-return valve 12 to the air motor 22 and drives the latter.
The used air leaves the air motor through the muffler 21. At the same time also the control pistons of the pilot
valve 8 and the holding air valve 14 are admitted with pressure from the right.
The left control side of the holding air valve 14 is deaerated through pilot valve 8 and the holding air valve 14
opens the opening area from the holding air throttle 11 through the adjustable holding air throttle to the air
motor 22.
This state remains unchanged until the air motor 22 stalls (through overcharge). If the tensioning cycle has to
be interrupted the blocking of the motor valve 6 must be suspended (press down lever 28).
Because of this the catch 26 is hooked out through the ejection bolt 30. At the same time the holding air valve
14 is closed so that the air motor 22 stalls.
Remark:If the strap is not transported after pressing the motor valve lever the procedure "Inserting the
strap"has to be done again. By pressing the flapper valve lever 23 the catch 26 is hooked out automatically.
So the started tensioning process is stopped and has to be restarted.
Sealing
The sealing action is started by pressing down the sealing valve lever 25. Sealing valve 5 switches and the
blocking of motor valve 6 is suspended.
The air motor 22 is held under pressure by the holding air throttle 11 and the holding air valve 14 in order to
avoid the rewinding of the feed wheel which is under pressure.
From sealing valve 5 compressed air flows to the pressure reduction valve 15 (to be adjusted at 5.3 bar/76
psi) as well as to the sealing cylinder 20. At the same time diaphragm 13 and through throttle 9 also pilot valve
8 are admitted with compressed air from the left.
Pilot valve 8 changes to opening and diaphragm 13 to locking. Since the right side of diaphragm 13 has a
smaller control piston surface than the left side, diaphragm 13 remains in a locking position and consequently
avoids the switching off of holding air valve 14. The piston of the cylinder 20 moves out and under the use of
a hydraulic pressure intensifier produces the necessary power to cut the sealing profile into the two straps and
to shear off the upper strap.

As soon as the upper strap is sheared off, the sealing valve lever 25 can be released. Sealing valve 5
switches to deaeration, the compressed air in cylinder 20 starts to flow back and escapes through the
pressure reduction valve 15 (back stroke area), sealing valve 5 and the lower part of the cylinder 20 into the
athmosphere.
The pressure in the line between pressure reduction valve 15 and sealing valve 5 drops continually.
As a result of this, the pressure on the left control side of diaphragm 13 is reduced.
The surface relation of the left to the right control side is modulated in such a way that diaphragm 13 switches
in dependence to the piston movement of the sealing cylinder and opens the input to the left control side of
holding air valve 14.
Holding air valve 14 interrupts the holding air. The pressure in the air motor 22 drops; the air motor can be
turned back by the tension in the strap. The two straps provided with the sealing profile can now interlock.
At this point the piston (piston with dies and cutter) is positioned approx. one to two mm (.040" to .080") from
its lowest position on its way to its initial position.
Removing the tool
The tool is opened by pulling the Flapper valve lever 23; the tool is then pushed away from the seal to the
right.
14.1 Adjustments
Tension speed / tension force
Throttle valve 7 limits the tension speed and also the tension force in the lower range of adjustments.
Factory presetting adjustment: 90 % of the maximum speed.
Sealing cylinder
The air pressure reduction valve 15 limits the entry pressure to the sealing cylinder 20.
Factory presetting adjustment: 5.3 bar (76 psi).
Important! The presetting adjustments must not be exceeded.
Timing of the interlock
Under normal conditions the holding air throttle 29 is screwed flush into the outside of the control valve body.
If the straps do not interlock properly (one or two notches do not interlock at all) the throttle has to be turned in
a clockwise direction; this causes a reduction of the holding air on the motor and the tensioned strap is held
with less power so that it will interlock quicker after sealing.
Attention!
Adjust holding air throttle in such a way that no tension marks on the bottom of the seal caused by the punch
will be noticed. If marks are noticed the punch might wear prematurely.
