2 Proper use
2.01 General
The PFAFF 8311 is available in three versions. The individual versions are described below,
see Chapter 2.02 Machine versions. All the machine versions are used for continuous sea-
ling of thin, thermoplastic materials, such as e.g. fleeces, felts, woven and knitted fabrics
using ultrasonics.
Any use of these machines which is not approved by the manufacturer shall be
considered as improper use! The manufacturer shall not be liable for any damage
arising out of improper use! Proper use shall also be considered to include com-
pliance with the operation, adjustment, service and repair measures specified by
the manufacturer!

4 Disposal
4.01 Environmental protection
Careless disposal of the machine and its components may lead to environmental pollution.
OThe materials used for the machine are steel, aluminium, brass and various plastic
materials. The electrical equipment comprises plastic materials and copper.
ODismantle assemblies into individual components.
ODispose of the components in a proper and environmentally friendly manner while
adhering to all statutory and operational regulations.
OThe machine is to be disposed of according to the locally valid pollution control regula-
tions; if necessary, a specialist ist to be commissioned.
Care must be taken that parts soiled with lubricants are disposed of separately
according to the locally valid pollution control regulations!
The final decommissioning and disposal requires a complete disconnection of the entire
power supply, the dismantling of the mechanical components and the disposal of the media
that may remain in the machine.
All safety and environmental aspects must be taken into consideration when dismantling
and disposing of the machine.
Risk of environmental damage!
OObserve the applicable national and regional regulations and the
manufacturer's instructions when disposing of the machine.
OSegregate the different operating and auxiliary materials and dispose of
them in a proper manner.
Risk of fatal injury from electric shock!
ODisconnect the power supply when carrying out the dismantling and
disconnection work.
OWork to disconnect the electrical components must only be carried out by
qualified electricians.
Risk of uncontrolled machine movements!
Sufficient energy reserves remain in various supply systems (e.g. electrics,
electronics, pneumatics) after disconnecting the power supply (emergency stop
switch) that could have dangerous consequences in the case of intervention by
an unqualified person.
OMake sure that the EMERGENCY STOP switch and the compressed air are
switched off.

5.02 Transportation inside the customer‘s premises
The manufacturer cannot be made liable for transportation inside the customer‘s premises
nor to other operating locations. It must be ensured that the machines are only transported
in an upright position.
5.03 Disposal of packing materials
The packing materials of this machine comprise paper, cardboard and VCE fibre. Proper dis-
posal of the packing material is the responsibility of the customer.
5.04 Storage
If the machine is not in use, it can be stored as it is for a period of up to six months, but It
should be protected against dust and moisture.
If the machine is stored for longer periods, the individual parts, especially the surfaces of
moving parts, must be protected against corrosion, e.g. by a film of oil.

The current operating statuses are indicated on the control panel 1. The machine is operated
with constant dialogue between the control unit and the operator; different pictograms and /
or texts are displayed for this purpose according to the operating status of the machine.
Pictograms or texts with a border represent functions that can be called up by pressing on
the respective points on the monitor. Pressing the respective function causes its immediate
actuation or activation/deactivation or another menu will appear (e.g. for entering a value).
Switched-on functions are indicated by an integrated LED.
Pictograms or texts without a border are only used for display purposes and cannot be called
up by pressing them.
