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

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 strapping
The strap is fed through the seal, around the package to be
strapped and again through the seal. The strap end is then
bent. The operator then tensions the loose hoop manually
making sure that the bent strap end is adjacent to the object
to be strapped.
Loading the strapping
Hold the upper strap with the left hand, lift the feed
wheel lifting handle with the right hand and slide the
tool over the strap from the right to the left
respectively from the rear to the front.
Tensioning the strapping
The tool is held tightly with the left hand being placed
on the sealing handle.The tension handle is now
moved forward and backward with the right hand until
the desired tension is attained.
When handling strap, always wear protective
gloves and safety glasses with side shields
which conform to ANSI Standard Z87.1.

11
A431en.teil2.fm
Sealing the strapping
With the right hand on the tension handle (in back
position as illustrated) push the sealing handle
forward to the stop with the left hand. Move sealing
handle backward into the initial position after
completion of the sealing action.
Releasing the tool
After completion of the sealing action the tool can be
released easily from the seal. By relifting the feed
wheel lifting handle the strap end can be removed from
the tool.
8 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.
• 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.
