Installing The Under Cover - JUKI LZ-2290C/X73257 Instruction Manual And Parts List

2. Installing the under cover

The under cover for the stitch skipping/double catching detection device differs from that for the standard
sewing machine in shape of the front section as shown in the figure given below.
When using the stitch skipping/double catching detection device with your sewing machine, the under cover
for the standard sewing machine should not be used.

* For the SD-29 (in the case "U220 Stitch skipping and double catching detecting function" is set to "1:
Enable"), the maximum sewing speed of the sewing machine is limited to 4000 sti/min. Consequently,
the LZ-2290C/X73257 is not provided with the hook cooling fan. (Maximum sewing speed of the stan-
dard sewing machine: 5000 sti/min).
When the SD-29 is not used (in the case "U220 Stitch skipping and double catching detecting function"
is set to "2: Disable") or when there is a risk that the hook becomes hot due to the environmental tem-
perature, the optional part (separately available), hook cooling set (part number: 40250042) should be
used.
Refer to "2-1" to "2-19" in the Instruction Manual for the LZ-2290C Series of sewing machine for the installa-
tion method of the under cover and for the setup method of the main body of sewing machine and electrical
components (excluding the stitch skipping/double catching detection device).
