Joints
You are fully responsible to review the joints made by your tool. Become familiar with the seal control and seal
adjustment described 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 follow 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 tensioning 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 loosened 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,
especially 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 accident 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.

7 OPERATION
Feeding the strap around the package
The strapping is fed around the package in the direction as
shown in the illustration. The strapping end is held tightly
with the left hand and pulled firmly towards the operator
with the right hand.
Loading the strap
The lifting handle is raised with the right hand. Insert
both thicknesses of the strap with the left hand. Lower
the lifting handle; be certain that the strap is held by the
strap guide.
When handling strap, always wear protective
gloves and safety glasses with side shields

Tensioning the strap
The tool is held tightly with the left hand
being placed on the sealing handle. The
tensioning handle is now moved forward
and backward with the right hand until the
desired tension is attained.
Sealing the strap
The sealing handle is moved forward
using the left hand until it hits the stop.
The handle is then moved back to its
initial position.
When sealing, the right hand holding the
tensioning handle absorbs the sealing
force.
Removing the tool from the tensioned strap
The lifting handle is raised with the right hand. The tool is
then pushed to the right from the seal.

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 ( 0.039 – 0.059”) in min. and must not exceed 2 mm (0.079”). 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).

10 SEAL ADJUSTMENT
The depth of the sealing mechanism and the cutter can be adjusted by displacing the stop.Place the tool as
shown and loosen the screw with an allen key. After displacing the stop retighten the screw.
• If sealing depth is not sufficient reset stop in the direction of the base plate.
• If sealing depth is excessive reset stop in the direction of the cover.

11 MAINTENANCE
Disassembly / Assembly
If base plate was removed for service- or repair works it is important to retighten the two screws N1.1185 with
tightening torque of 120 Nm / 87 ft lb when assemble.
12 CLEANING
In case of heavy dirt and when painted straps are used the punch, dies, gripper and feed-wheel must be
cleaned regularly.
Normally it is sufficient to blow out the parts with the help of an air gun.
