(2) How to load a bobbin in the device
If the bobbin case is not correctly placed in the bobbin setting section ❺ of the device, an
error such that the gripper fails to catch the bobbin case can occur.
If the bobbin case is not correctly placed in the device, the bobbin case can drop from the
device without raising its claw.
Keeping the bobbin case lever held opened widely with your fingers, insert the bobbin
case into the hook as far as it will go. If the lever is not opened widely enough, the bobbin
may interfere with the claw part of the hook to prevent the bobbin case from being inserted
to its locking position. If the bobbin case is not correctly inserted in the hook, it may drop
during sewing to cause needle breakage or bobbin case breakage.
Lever is not
opened sufficiently
In order to set the bobbin case in the hook section without fail, do not carry out attach-
ment, removal or setting of the bobbin case directly by hand but place the bobbin case
firstly on the standby position.
After you have set the bobbin case in the device, make sure that the bobbin case has not
dropped from the device.
