8. ELECTRIC MECHANISM

８-８-１. Light work clamp

For pneumatic specifications, the hose connections can be changed so that the work clamp are made to lower gently when the work clamp pedal is depressed to the 1st step, and firmly when the work clamp pedal is depressed to the 2nd step. This makes it easier to carry out position matching when attaching small articles such as labels.

[Memory switch setting]

Set memo-42 (memo-3b: KE-436B, 436C) to 5 for two-pedal mode so that the work clamps lower in the order of left then right for the standard hose connection. (Refer to “8-6./8-7. Explanation of the memory switches”.)

[How to use]

1.Depress the work clamp pedal to the 1st step to lower the work clamps and apply a light pressure. You can then position small articles such as labels at this time.

2.After checking that everything is positioned correctly, depress the work clamp pedal to the 2nd step to firmly clamp the article being sewn.

3.Press the start pedal to start sewing.

Other hose connections and corresponding operations

The hoses can be connected in combinations other than the one shown above so that only one side of the work clamp operates in light work clamp mode.
