4.1 Cleaning

Caution Risk of Injury !

Turn the main switch off.

Maintenance work on the unit may only be conducted with the machine

turned off.

A clean machine protects against malfunctions !

Daily cleaning:

–

Particularly the areas around the needle thread guides and

tensions, thread controller spring and hook are to be cleaned of

sewing dust and lint accumulations (e.g. with a compressed air

gun).

For cleaning the parts attached under the foundation plate tilt the

machine head to the side.

–

Clean the motor ventilator grill 1 with a compressed air gun.

–

Check the water level in the pressure regulator.

The water level should not be allowed to rise to the filter insert 2.

After screwing in the drain screw 4 blow the water out of the water

separator 3 under pressure.

Dirt and condensation water are eliminated through the filter insert 2.

Wash out the dirty filter bowl and filter insert with naphtha after a

certain period of operation and blow clean with compressed air.

ATTENTION !

Do not use solvents for washing!

They destroy the filter bowl.
