than the requirements for the sewing machine’s total
air consumption.
Insufficient pneumatic delivery capability may cause
problems with correct operation.
The ambient temperature should be within the range
of 5°C to 35°C during use.
Temperatures which are lower or higher than this may
cause problems with correct operation.
The relative humidity should be within the range of
45% to 85% during use, and no dew formation should
occur in any devices.
Excessively dry or humid environments and dew formation may cause problems with correct operation.
Avoid exposure to direct sunlight during use.

During an emergency stop, the thread is trimmed and the needle bar stops in the
raised position.
*Note:
When the motor operates in reverse to raise the needle, the thread take-up will stop at a position which is lower than its
normal stopping position. As a result, the thread take-up will rise slightly at the sewing start, and this may result in the
thread pulling out under certain conditions.

12. SETTING THE WORK CLAMP MODE
12-1. Light work clamp
For pneumatic specifications, the hose connections can be changed so that the pressers are made to lower gently when the
presser pedal is depressed to the 1st step, and firmly when the presser 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-3b to 5 for two-pedal mode so that the pressers lower in the order of left then right for the standard hose
connection. (Refer to “11. Changing special functions using the memory switches”.)
< Hose connections for light work clamp operation by both pressers >

Plug
1088Q
[How to use]
1. Depress the presser pedal to the 1st step to lower the pressers 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 presser 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 presser operates
in light work clamp mode.

16. OPTIONAL PARTS
Two-step foot switch
This is a pedal-type foot switch.
Liquid cooling tank
This helps to prevent thread breakages caused by friction when
using synthetic threads.
Fill the tank with silicone oil (100 mm2/s).
Three-pedal foot switch
The switch has an independent left work clamp switch (left side),
right work clamp switch (center) and start switch (right side).
Work clamp plate, OT
Use according to particular sewing needs in order to provide an
even clamping force.
Programmer assy
Used to create sewing patterns for the KE-436C. It can also be used
to display error messages.
Thread breakage detector device
Available as rotary type or fiber type, stops sewing when a thread
breakage is detected and warns the operator.
Needle cooler device
This is a pneumatic-type needle cooler which prevents the thread
breaking due to heat. It is particularly useful when sewing thicker
materials at high sewing speeds.
Air wiper device
The thread wiper is driven by a pneumatic cylinder.
2-step thread tension device
Allows the upper thread tension to be switched between two
settings at any position desired by using the programmer.
