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.
