Lightly press against the feed plate

1) Move feed plate ❶ forward. Lightly press sub table B ❷, supplied with the unit. Then, temporarily tighten setscrews ❸.

If the sub table B does not support

the feed plate when the latter moves forward, the presser foot fails to hold the material securely, causing stitch skipping and thread breakage.

On the other hand, if the sub table B

is excessively pressed against the feed plate, the feed mechanism can lose synchronism due to an excessive load when it is moved forward.

2) Fit sub table A ❹, supplied with the unit, to the bed and sub table B ❷.

• Do not leave the USB device or USB cable connected to the USB port while the sewing machine is in

operation. The machine vibration can damage the port section resulting in loss of data stored on the USB device or breakage of the USB device or sewing machine.

• Do not insert/remove a USB device during reading/writing a program or sewing data. It may cause data breakage or malfunction.

• When the storage space of a USB device is partitioned, only one partition is accessible.

• Some type of the USB device may not be properly recognized by this sewing machine.

• JUKI does not compensate for loss of data stored on the USB device caused by using it with this sewing

machine.

• When the panel displays the communication screen or pattern data list, the USB drive is not recognized

even if you insert a medium into the slot.

• For USB devices and media such as CF(TM) cards, only one device/medium should be basically con-

nected/inserted to/into the sewing machine. When two or more devices/media are connected/inserted, the machine will only recognize one of them. Refer to the USB specications.

• Insert the USB connector into the USB terminal on the panel until it will go no further.

• Do not turn the power OFF while the data on the USB ash drive is being accessed.

Non-slip adhesive tape (white)

In the case of sewing a light-weight oppy material, cut the accessory non-slip adhesive tape into the size of 240 mm × 5 mm as shown in the gure. Stick it onto the underside (knurled side) of the presser foot to prevent the material from opping. In the case the material is likely to op around the center (near the second buttonhole) of the presser foot, in particular, it is recommended to stick the non-slip adhesive tape onto the feed plate to effectively prevent the material from opping.

1. Before sticking the non-slip adhesive tape, wipe clean the underside of the presser foot (knurled side) and the feed plate surface onto which the non-slip adhesive tape is to be stuck.

2. Stick the non-slip adhesive tape while carefully preventing it from protruding outside

the front/rear and right/left edges of the presser foot and outside the slot in the feed plate. If the non-slip adhesive tape protrudes from those sections, the tape is likely to peel off easily.

Undersurface

300 mm

Surface smoothness increasing adhesive tape (black)

This adhesive tape is intended to be applied to the undersurface of the feed plate to help increase its surface smoothness. If the adhesive tape has worn out or come away, remove the defective tape and apply the accessory adhesive tape to the feed plate.

1. In the case the adhesive tape is not applied to the undersurface of the feed plate, chattering noise can be produced since the undersurface of the feed plate and the bed are directly rubbing against each other.

2. Periodically remove the feed plate to wipe it clean of oil stains and grime.
