that when sewing this kind of material the feed towards the presser foot be always sufficient, by means of lightly pushing the tricot on both sides of said presser foot. 7. The machine operates too slowly The motor does not work correctly (ask the expert!) : a) tension of drive belt may be too tight or too loose (ask the expert !) ; b) the sewing machine has been idle for a long time in a moistened room. In such a case it must be placed in a room with normal temperature for some time and subsequently the machine should be oiled; c) if oil of doubtful quality has been employed, the machine became gummed. If lubrication of the sewing machine at the oil points with petrol does not improve its condition, the machine must be demounted and cleaned (ask the expert!). General notice To prevent any damage to the presser foot, place a piece of material under it, as far as possible. If the machine will be idle for some time, you may do alike. In order to avoid thread jamming, make sure that after every sewing operation the thread take-up lever is raised to its uppermost position. This precaution will greatly help to avoid any troubles.

does
not
improve
its
condition,
the
