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.

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.

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.

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.

6.3 Adjustments

6.3.1 Preselecting of strap tension and tensioning speed

Do not adjust the tensioning force too high.
If the tensioning force is higher than the tensioning strength of the strap,
the strap will tear while the tensioning.

Tensioning force and tensioning speed can be
preselected at the control head.

Loose lock screw;
press the control head against the tool
and turn it.

Turning clockwise increases;
turning counterclockwise decreases the
tensioning force and the tensioning speed
resp..

Tight lock screw.

6.3.2 Adjusting the welding time

Depending on the size and quality of the strap,
different welding times are required.

The welding time can be adjusted at the
adjusting crew.

Turning clockwise increases,
turning counterclockwise decreases the
welding time.
