retrieval.
4) The pressing amount can be set with [RIGHT ]
key

The setting range is
−
100 to 300. The more the

Set the knife pressing amount as small as
possible in order to protect the knife and the
knife holder and maintain the durability.

large, malfunction of the drive motor or
breakage of the knife will be caused.

Adjusting the stopping time of the knife lower position
The stopping time at the knife lower position can be extended.
Setting of 50 to 500 ms can be performed with the memory switch No. 55.
(Refer to “14. MEMORY SWITCH” P.68.)
Even when the pressing amount is increased, the result is not effective, when the cut length is
excessively long or sewing heavy-weight materials, set the stopping time of the knife lower position
longer than the specified time.
Knife holder Nos. “0” to “9” to which 10 kinds of knife pressing amounts have been set can be set to
the pattern data using memory switch No. 40. (Refer to “Setting the pattern data of cloth cutting knife
pressing amount”, p.44.)
