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 responsable 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.

5.1 Sound information
The A-weighted equivalent continuous sound level at the work place of the machine operator is
typical 79 dB (A).
This value was determined according to DIN 45 635 T3 (11.85).
5.2 Vibration information
The weighted effective value of the acceleration typically amounts to less than 2,5m/s2.
This value was determined according to DIN EN 28 662 T1 (01.93).
6 INSTALLATION
6.1 Compressed air connection
The air tube is preferably connected to the tool using a quick coupling. An air unit consisting of a separator for
water and dirt, a pressure regulator with a manometer and a lubricator should be installed within a distance of
15 ft / 5 meters. The compressed air must be free from dirt, rust and moisture.

Feeding the strap around the package
The strap is fed around 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.
Loading the strap
Lift and hold the air motor with 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.
The feed wheel is lowered to the strap by
releasing the air motor.

Tensioning the strap
Tensioning the strap by pressing the valve button.
It is possible to change tensioning force by
adjusting the pressure regulator at the air unit.
Attention!
Never exceed the maximum air pressure of
6 bar / 87 psi.
Sealing the strap
The sealing handle is moved forward using the left
hand until it hits the stop. Then the handle is
moved back in its initial position.While sealing the
right hand absorbs the sealing force by holding
the air motor. Attention!
Don’t seal with air motor running.
Releasing the tool
Lift the air motor with the right hand and remove
the tool from the sealed strap to the right.

10 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
insufficient 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).

11 SEAL ADJUSTMENT
The sealing mechanisms stamping and cutting depth can be adjusted with the socket wrench N4.1408
delivered with the tool.
Procedure:
• Place the tool as shown.
• Loosen both screws N1.1168 and unscrew
them about three rotations.
• If sealing mechanism is adjusted too high
displace the stop in the direction of the base
plate.
• If sealing mechanism is adjusted too low
displace the stop in the direction of the cover.
• Tighten screws.
12 MAINTENANCE
Depending on the working conditions and the use of the tool the following maintenance has to be made
periodically:
12.1 Air - unit
• Checking the air-pressure daily.
• Checking 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
12.2 Cleaning
If impact of dirt and dust is considerable and if painted (cinccoated) straps are used the feed wheel must be
cleaned regularly. Normally it is sufficient to blow out this part by using an air gun.
12.3 Lubrication
The worm gear is filled with MOLYKOTE LONGTERM 00. 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
ESSO BEACON 2 or with any equivalent product.
Assembling notice:
The screws N1.1182 and N1.1184 have to be
tightened after each disassembling with the
prescribed torques.
The use of a torque wrench is absolutely
necessary.
N1.1182 = 42 Nm N1.1184 = 85 Nm

13 ACCESSORIES
13.1 Suspension A33.0113
It is possible to suspend the tool for strapping in vertical
position.
Order the suitable suspension separately under item no.
A33.0113.
13.2 Using tool with horizontal handle
Upon request the tool can be supplied with a bolt A33.4101 and
a grip ball N4.1116. When using tool for horizontal applications,
the operator holds the tool on the grip ball during tensioning.
Install the handle as follows:
Remove side cover A33.1190 and break the marked position.
Reassemble side cover and screw bolt with mounted ball into
the body. A33.1190
