10-8.Adjusting the work clamp lift amount
The maximum work clamp lift amount is 17 mm from the top of the needle plate.
The lift amount for each model is adjusted as shown in the table at the time of shipment.
1. To adjust the work clamp lift amount, loosen the bolt q and move the presser arm lever plate w up or
down.
2. Apply grease to the bottom of the presser plate e to the top of the presser arm lever plate w and to the
sliding part of the work clamp r (grease is already applied at the time of shipment), and check that the
movement becomes easier.
3. Check that there is a gap between the presser arm lever plate w and the presser plate e when the work
clamp r is lowered.
* If movement is sluggish when the work clamp r is being raised and lowered, it may not be possible to
increase the work clamp r lift amount.
* If the work clamp r cannot be raised or lowered, error code “E-61” or “E-63” will be displayed.
