Cautions Before Operation; Precautions For Use - JUKI AE-200A Instruction Manual

!. CAUTIONS BEFORE OPERATION

Following items have to be checked every working day before the operation of the machine
and before the start of work hours.
1. Ascertain that the oil pan is filled with the predetermined amount of oil.
2. Never operate the machine unless the oil pan has been filled up with oil.
3. Ascertain that the pressure gauge indicates the designated air pressure of 0.5 MPa.
* (This is necessary particularly when the compressor is stopped for a lunch break or the like.)
If the compressed air pressure is equal to or less than the designated value, troubles such
as interference between the parts can occur. It is therefore necessary to carefully check the
compressed air pressure.
4. Check whether the needle thread/bobbin thread need to be replenished.
5. To perform sewing immediately after turning ON the power switch, perform trial stitching first,
then proceed with sewing of actual products after the test sewing.
6. In order to prevent the sensor from showing a detecting failure, be sure to clean thread waste
around the sensor using an air gun once or more times a day.

Precautions for use

1. For a wider material, fold the material toward you and sew it while putting your hand on it. If you
don't guide the fabric by hand during sewing, the material may warp at the end of sewing.
2. When sewing some patterns, it is also necessary to put your hand on the material at the end of
sewing.
3. Setscrew for the presser bar base

) Never loosen setscrew 1 in the presser bar
base. If it is loosened, the walking foot move-
ment timing will change from the correct one.
2) When it is really necessary to loosen setscrew
1 , it should be loosened when the walking foot
comes down to contact the throat plate surface.
