the ground terminal of the plug. The wire with green insulation (with or without
yellow stripes) is the grounding wire.
Check with a qualified electrician or service person if the grounding instructions are
not clear or if in doubt about the proper grounding of the machine. Do not modify the
plug provided; if it will not fit the power outlet, have the proper outlet installed by a
qualified electrician.
This product is designed for use on a nominal 230 volt AC circuit and has a grounding
plug.
DANGER!
Improper installation of the grounding can result in electrocution.

9
1.6 Before Operating

2.4 Safety Devices
DANGER!
Operate the machine only when all safety devices are at their place and are functioning
correctly.
The machine has been constructed in accordance with the applicable legal regulations.
The machine is reliable in operation. Nevertheless the machine may constitute a danger if it
is operated in improper or undue condition.
Danger points that cannot be avoided due to equipment design are equipped with safety
devices. If necessary, these points are marked on the machine with warning signs, and in
the manual under working safety instructions.
The machine is equipped with safety devices as:
Warning labels
Live parts are covered
Table cover with screw fixed (1)
Only Polypropylene strapping can be used in this machine. The use of other synthetic
Straps can produce substances hazardous to health.
Caution!
The heating unit operates at a very high temperature in order to melt the P.P. strapping.
To prevent burns, avoid contact with this area. (2)
To move the machine, the two lockable casters (3) must be unlocked. Relock the two
casters when the machine is in its new position.
The machine is turned on when it is connected to AC power and the main power switch,
located on the front operating panel, is placed in the ON position. After approximately 1
minute, the heating element will reach its operating temperature and the machine will be
ready for use.

14
If it is necessary to make adjustments inside the machine during operation, after a strap
jam for example, the table top can be unscrewed. Observe caution as the machine is still
fully functional with the covers removed. If machine with safety switch, when table top is
opened, safety switch is activated. This will remove power but heating element is keeping
heating.
