*    The frames of the LBH-1790A, LBH-1790AB and the LBH-1795A are the same. Therefore, it is possible to modify the specification by changing the parts.

Caution:  When exchanging the needle plates between the LBH-1790A and the LBH-1790AB, it is necessary to perform the model setup work in the memory because the distance between the needle entry and the knife is different from the standard mode.
 


*    The LBH-1796A is equipped with its special frame and not compatible with the LBH-1790A, LBH-1790AB nor the LBH-1795A. Therefore, it is not possible to modify the specification such as mounting the presser types 1 through 3.

*    The timing gauge of the LBH-1790A is different from that of the LBH-1790AB. This is because the length of the timing gauge is changed according to the thickness of the needle plate. The basic timing of the needle and the hook is the same.

*    If the feed width exceeds 5mm on the LBH-1790A, it is necessary to replace the presser arm and the oil shield.
(For details, see Special specification-related 2 in Parts Book.)

*    If the feed direction exceeds 41mm on the LBH-1790A, it is necessary to replace the presser arm.
(For details, see Special specification-related 2 in Parts Book.)

*    The non-lubrication specification can be mounted regardless of model/specification. For modification, replace the following three parts.
1)    RP hook:    Part No. 40006345
2)    RP bobbin case:    Part No. 40006349
3)    Hook joint:    Part No. 13729603
Caution:  The maximum rpm of a non-lubrication hook is restricted to 3300sti/min.
