7.1 Cleaning
A clean sewing unit protects from malfunction!
Clean and check daily:
–
Clean the area around the hooks 2 and 3 with the compressed air
pistol.
– When changing the bobbin always clean the lenses of the light
barriers 1 and 4
of the remaining thread monitor with a soft cloth.
– Cleaning of the filter ring 6 at the vacuum valve 5:
Blow out with compressed air pistol.
Clean and check daily:
–
Check the water level in the pressure regulator.
The water level must not reach the filter insert.
After screwing in the drain screw 2 blow the water
out of the water separator 1 under pressure.
The filter insert separates dirt and condensed water. After a certain
time of operation
wash the dirty filter tray and the filter insert with benzine and blow
them clean with the compressed air pistol.
ATTENTION!
Do not use any solvents for washing out the filter tray and the filter
insert!
They destroy the filter tray.
