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
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.

5.6 Sound information
The A-weighted equivalent continuous sound level at the work place of the machine operator is
typical 84 dB (A).
This value was determined according to DIN 45 635 T3 (11.85).
5.7 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 compressed air is connected to the reducing coupling N6.5133 using a 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.
6.2 Suspension of tool
It is possible to suspend the tool on a spring loaded balancer using various suspension brackets.
They have to be ordered separately (see paragraph "ACCESSORIES").
7 MAINTENANCE
Depending on the working conditions and the use of the tool the following maintenance has to be made
periodically:
7.1 Air-unit
• Checking the air-pressure daily (never exceed 87 psi / 6,0 bar).
• Checking oil-level daily.
• Checking the water separator daily (unless automatic), draining when necessary.
• Cleaning the filter following the instructions of the manufacturer of the air-unit.
Oil for the air unit
HL or CL ISO-VG 10
7.2 Lubrication
When being exchanged, all valve parts and other movable parts have to be greased with grease of type
ESSO BEACON 2 or with some equivalent product.

8USE
8.1 Feeding the strap
The strap is fed through the seal, around the package
to be strapped and pushed again through the seal.
Then the strap end is bent.
Afterwards the operator tensions the loose hoop
manually making sure that the bent strap end is
adjacent to the object to be strapped.
8.2 Tensioning the strap
The strap is tensioned with a suitable tensioner
(e. g. Fromm model A451).
8.3 Sealing the strap
Place the sealer on top centre of the seal.
Notch the seal with the strap by pushing the valve
lever until it stops.
It is possible to release the valve lever immediately
after pushing because of the tools automatic sealing
cycle.
Remove the sealer after finishing sealing cycle.
Always wear safety
glasses with side shields
which conform to ANSI
Standard Z87.1.
When handling strap,
always wear protective
gloves.

10 JOINT CONTROL
A regular control of the joint is necessary. The joint can be checked visually and the person controlling can
easily judge the quality of the joint. Following illustration shows a proper joint:
Sharp edged or misformed joints which do not appear as shown have to be taken away from the load
immediately. The tensile strength of these joints is insufficient and they could cause serious injury.
Having faulty joints proceed as follows:
• Checking the sealing cycle for improper use.(see 8. USE)
• Having faulty joints in spite of proper use inspect the tool for worn or damaged parts. In case of
wearing out or damaging replace tool parts as needed.
11 EXCHANGE OF WEARING PARTS
11.1 Exchange of cutting jaws and notching knives
Procedure:
• Unscrew cylinder cover A46.2150 (7 recessed countersunk head screws).
• Remove diaphragm A46.2151.
• Unscrew piston plate A46.2152 (screw N1.2114), push piston plate against the pressure spring at
the same time.
• Remove pressure spring.
• Disassemble screws N1.1118 and remove jaw assembly.
• In order to be able to exchange notching knives and cutting jaws the side plates have to be
removed from the jaw assembly. For this remove screws N1.2108.
• Assembling in opposite order.
Important!
Safe screw N1.2114 with Loctite 222.
