为了安全地使用本缝纫机的注意事项
FOR SAFE OPERATION
危险
DANGER
1. 为了防止触电事故, 打开电源时, 请不要打开马达电气箱盖, 也不要触摸电气箱内
的零件。
To prevent possible accidents due to electric shocks, neither open the cover of
motor electrical box nor touch the component(s) inside the electrical box.
2. 变更图案后, 请确认落针位置。万一压脚超越图案范围, 缝制中有可能机针与压脚相
碰,发生断针的危险。另外, 请确认被设定的压脚和安装到缝纫机的压脚是否一致。
Make sure of the needle entry after changing the pattern. Should the pattern protrude
from the work clamp check, needle interferes with the work clamp check resulting in
the danger of occurrence of needle breakage or the like. In addition, check that the
work clamp check which has been set corresponds to that which has been installed
on the sewing machine.
注意
WARNING
1. 打开(ON) 电源开关后, 操作盘上什么也不显示时, 请关闭(OFF) 电源开关, 然后确
