1 SAFETY INSTRUCTIONS
Read these instructions carefully. Failure to follow these instructions can result in severe personal injury.
Eye injury hazard
Failure to wear safety glasses with side shields can result in
severe eye injury or blindness. Always wear safety glasses with
side shields which conform to ANSI Standard Z87.1.
Operation
Tool must not be used by persons not properly trained in their use.
Before tensioning strap, read and understand the tool operating
instructions. Failure to follow the operating instructions or improper
load positioning could result in strap breakage.
Become familiar with your tool and keep fingers away from areas
that can pinch or cut.
Joints
You are fully responsible to review the joints made by your tool.
Become familiar with the seal control and seal adjustment descri-
bed in this operation manual. Misformed joints may not secure the
load and could cause serious injury. Never handle or ship any load
with improperly formed joints.
Dispensing strap
Only dispense strap from a dispenser specifically designed for
strap.
Tuck strap end back into dispenser when not in use.
Protective gloves
When handling strap, always wear protective gloves.
Strap warnings
Never use strap as a means of pulling or lifting loads. Failure to fol-
low these warnings can result in severe personal injury.
Strap breakage hazard
Improper operation of the tool, excessive tensioning, using strap
not recommended for this tool or sharp corners on the load can
result in a sudden loss of strap tension or in strap breakage during
tensioning, which could result in the following:
• A sudden loss of balance causing you to fall.
• Both tool and strap flying violently towards your face.
Note as follows:
• If the load corners are sharp, use edge protectors.
• Place the strap correctly around a properly positioned
load.
• Positioning yourself in-line with the strap, during tension-
ing and sealing, can result in severe personal injury from
flying strap or tool. When tensioning or sealing, position
yourself to one side of the strap and keep all bystanders
away.
• Use the correct strap quality, strap width, strap gauge and
strap tensile strength recommended in this manual for
your tool. Using strap not recommended for this tool can
result in strap breakage during tensioning.
Cutting tensioned strap
When cutting strapping, use the proper strapping cutter and keep
other personnel and yourself at a safe distance from the strap.
Always stand to side of the strap, away from the direction the loo-
sened strap end will fly. Use only cutters designed for strap and
never hammers, pliers, hacksaws, axes, etc.
Fall hazard
Keep your working area tidy. Untidiness of your working area may
cause a risk of injury. Maintaining improper footing and/or balance
when operating the tool can cause you to fall. Before tensioning
and especially in elevated areas, always establish good balance.
Both feet should be securely placed on a flat, solid surface, espe-
cially when working in elevated areas. Do not use the tool when
you are in an awkward position.
Pay attention to the rules and regulations for preventions of acci-
dent which are valid for the work place.
Tool hazards
A well maintained tool is a safe tool!
Check tool regularly for broken or worn parts. Do not operate a
tool with broken or worn parts.
Never modify any tool. Modification can result in severe bodily
injury.

6INSTALLATION
Compressed air connection
The compressed air should be connected to the tool preferably by a quick disconnector.
It is very important to clean the compressed air with an air unit
consisting of a separator for water and dirt, a pressure regulator with a
manometer and a lubricator.
The maximum length of the air tube between air unit and tool has to be 5 m / 15 ft.
Suspension of tool
It is possible to suspend the tool on a balancer using one of the various suspension brackets available.
Depending on the application of the tool the appropriate suspension bracket is mounted.

7 OPERATING CONTROLS
8OPERATION
8.1 Feeding the strap around the
package
The strap is fed arround the package in the direction
as shown in the illustration. The end of the strap is
held tightly with the left hand and pulled firmly
towards the operator with the right hand.
8.2 Loading the strap
Lift and hold the flapper valve lever with the index
finger of the right hand. The left hand inserts the two
straps lying precisely upon another into the tool until
they hit the strap stops. The lower strap end must
slightly protrude the end of the base plate. Release
the flapper valve lever - the flapper closes and the
feed wheel is lowered to the strap.

8.3 Tensioning the strap
The motor valve lever is pressed down with the
thumb of the right hand so that the catch locks. Let
the tool tension until the motor stalls.
If the tensioning cycle has to be interrupted (faulty
strapping, applying of corner protection angles)
press the red lever.
8.4 Sealing the strap
Hold the strap which is reeled off from the strap coil
with the left hand . Press and hold down the sealing
valve lever until the strap is cut off.
Release the sealing valve lever.
8.5 Removing the tool from the
tensioned strap
Hold the cut strap end firmly with your left hand.
Lift the flapper valve lever with the right hand and
push the tool hard to the right from the tensioned
strap.
Release the flapper valve lever.

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).

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.
