1-3 Application
1) Standard type (SS)
It is suited for the wide using range from light-weight general fabrics to medium- and heavy-weight fabrics.
(It is especially suited for the process for which a high speed revolution of the sewing machine is required or
the process for which hook lubrication is required in accordance with the nature of thread used.)
2) Dry type (DS)
It is suited for the wide using range from light-weight general fabrics to medium- and heavy-weight fabrics.
(It is most suited for the process of sewing newly developed materials in the market of ladies’ wear, shirts, silk,
coat, etc., or the complete dry process of light-weight fabric, etc. to which the oil stain is particularly disliked.
3) For hard-to-sew materials and foundation garment (DF)
It is suited for the process for which handling performance under low speed and low pressure of presser foot
is particularly required when sewing foundation garment or the like.
(Particularly, this type is effective for the assembly process of brassieres or the like, or sewing hard-to-sew
materials. It is suited for the process for which handling at low speed is required.)
4) For heavy-weight materials (SH)
It is suited for sewing heavy-weight materials such as denim, vinyl leather, etc.
1-4 Cautions when operating
1) Be sure to drain oil from oil tank and attach the air vent cap (red rubber cap) attached to the air vent (gold
bushing) located on the side of machine bed when transporting the sewing machine.
2) When placing the SS or SH type sewing machine head on a stand or the like before setting up the sewing
machine head on the table, take care whether there is a protrusion under the machine head to protect the oil
tank from damage.
3) Even when using RP hook with the SS type machine, do not drain oil from oil tank. (Seizure of hook shaft
metal will result.)
In addition, when using the RP hook, loosen the oil amount adjusting screw until it will go no further and adjust
so that oil does not come out from the front of hook shaft.
4) To protect accident when performing maintenance, be sure to securely set the safety switch connector to the
control box.
5) Oil is kept in the gear box for lubrication. Replacement of oil is not necessary. Do not remove the lid of gear
box unless it is necessary.
* When the lid of the box has been removed, it is necessary to replace the packing with a new one.
6) When making the sewing machine run idle, be sure to operate the sewing machine after removing the bobbin
case.
When the bobbin thread is in the bobbin case, the thread is protruded from the bobbin case by running idle of
the machine and the thread is entangled in hook race or hook shaft. As a result, the machine will be out of
order.
