Notes on the sewing machine with regard to ambient conditions,
treatment, cleaning and safety

Ambient conditions:

The recommended ranges are:

Ambient temperature -10° to 40°C (50° to 104°F)
Air humidity 20 % to 80 %

This machine is a high-quality electro-mechanical device. It is designed for household purposes and
should always be supervised when in use.
Make sure that it is not subjected to:
dust, severe dampness, direct sunlight, static electricity, heat-producing objects, corrosive chemicals or
liquids.
The machine must be used on a free surface, for ventilation purposes, which is both firm and even.

Treatment:

Always protect the machine against damage by hitting or dropping.

Cleaning:

Housing:

To clean the housing, use a dry, clean and soft cloth which is free of fluff. To remove any stubborn dirt,
use a soft cloth with a neutral cleansing agent for plastic materials.
Please note!
Do not use any insecticides or chemical products such as petrol (gas) or thin chemicals for cleaning the
housing.

Display:

If necessary, clean display with a soft cloth moistened with a little water.

Safety:

1. The machine must be put into operation according to the indications on the specification plate.
2. Do not place any objects in openings on the machine.
3. Do not use the sewing machine if:

- there is visible damage,
- its function is disturbed,
- it is wet, e.g. with condensation.

4. Do not pull the mains plug out of the socket by its cord.
5. If this appliance is used for another purpose than that intended or if it is wrongly operated, we will not

accept any liability for any damage caused.

6. To avoid the risk of electric shock, do not open the machine. There are no parts inside the machine

which the user can repair. This is solely the responsibility of our qualified service staff.

7. Be sure to use only original PFAFF parts.
