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 g lasses 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 a reas
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.
T ool 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.

8 SEAL CONTROL
A regular control of th e seal is necessar y. The seal can be chec ked visually and the per son controlling ca n
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 b e 1-1 ,5 mm in mi n. and 2 mm in ma x.. T he upp er str ap mus t be sh eared clea n and
the cutter must not leave scratch marks on the lower strap.
Incorrect seal (the sealing mechanism is adjusted too high)
This stamped seal i s not deep enough an d the upper strap is not sheared .The tens ile stren gth 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 l ower strap i s scr atched by the cutte r. Al though th e tensi le st rength 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).

A335T2.en.fm
9 SEAL ADJUSTMENT
The sealing and cutting depth of the sealing mechanism and the cutter can be adjusted with the use of the
hexagon key N4.1408 which is supplied with the tool as follows:
• Place tool as shown above.
• Loosen both screws N1.116 8 and open them
by approx. 3 revolutions.
• If sealing depth is not sufficient reset stop in the
direction of the base plate.
• If sealing depth is excessive reset sto p in the
direction of the body cover.
• Retighten screws N1.1168.
Assembly Instructions
After every di sa ss em bly it is essential to ret i gh te n
screws N1.1182 and N1.1184 with the
recommended torque when reassembling. The
use of a torque key is necessary.
10 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.

11 ACCESSORIES
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 A33.1160 and break the marked
position.
Reassemble side cover and screw bolt with mounted
ball into the body.
Suspension
It is possible to suspend the tool for strapping in
vertical position.
Order the suitable suspension separately under item
no. A33.0113.
