vent (golden bushing) located on the side face of the machine bed when transporting the sewing machine.
2) In the case where placing A-SS or A-SU, A-SR type machine on a stand or the like before setting the machine to the
machine table, to protect the oil tank from damage, take car if there is any protruding object under the stand or the like.
3)
Be sure to securely set the connector of the safety switch to the control box to prevent accidents at the time of maintenance.
4) Oil is kept in the gear box for lubrication. It is not necessary to replace the oil. Do not remove the gear box cover
except when it is necessary.
* When the box cover has been removed, it is necessary to replace the packing.
5) Be sure to operate the sewing machine with the bobbin case removed when making the sewing machine run idle.
If the bobbin thread is in the bobbin case, the thread protrudes from the bobbin case and is entangled in the hook
race or the hook shaft. As a result, the trouble will be caused.
