Cleaning the machine

.02
The cleaning cycle required for the machine depends on following factors:
● Single or several shift operation
● Amount of dust resulting from the workpiece
It is therefore only possible to stipulate the best possible cleaning instructions for each indi-
vidual case.
Fig. 10 - 01
These maintenance intervals are calculated for the average running time of a
single shift operation. If the machine is operated more than this, shorter inter-
vals are recommended.
For all cleaning work the machine must be disconnected from the mains
by switching off the on/off switch or by removing the mains plug!
Danger of injury if the machine suddenly starts up .
Care and maintenance
To avoid breakdowns, the following cleaning
work is recommended for single shift ope-
ration:
● Swing out the cover plate and tilt back
the sewing head.
● Clean the hook and hook compartment
daily, more often if in continuous opera-
tion.
Return the machine to its up-
right position using both hands!
Danger of injury by crushing
between the edge of the
machine and the table top!
