Chapter 1 Preparation of Embroidery Machine
DANGER
Embroidery machines should be installed only
by trained engineers.
Electric wiring should be laid by your distributor or electric experts.
A machine weighs more than 600 kg. Installation should be carried out by 4 or more workers.
Do not connect the power source until installation is completed. Doing so may start the machine unintentionally through an accidental
activation of the START switch, resulting in
bodily injuries.
Install a machine in a place away from a highfrequency welding machine or other machines
that may generate a strong electric noise. Failure to do so may cause the embroidery machine
to malfunction.
Be sure to connect the ground. If the ground
connection is not secure, you run a high risk of
receiving a serious electric shock, and problems
with correct operation may also occur.
Secure the machine with the casters when installing it so that it will not move by placing the
leveling seat on the sound floor.
* After installation is completed, get the power supply from a dedicated outlet.

3-6 Lubrication to Needle Bar Case
Proper lubrication is necessary for keeping the machine head in good condition.
CAUTION
Turn off the power switch before starting any cleaning work, otherwise the machine may operate if the start
switch is pressed by mistake, which could result in injury.
Before operating the machine for the first
time after unpacking or after leaving the
machine without operation for a long
period of time, supply one or two drops of
oil to two sections of the needle bar. (See
the left figure.)
Note) • Use the Brother's specified embroidery ma-
chine oil (Nisseki Embroidery Lube No. 10
or the equivalent).
• Supplying an excessive amount of oil will
cause dripping onto the material.

Selecting needle
• When using special threads such as gold,
silver, and rame yarn, use a heavy-duty
needle (#11 ~ #16). For better finish, paste
the waxed paper on the back of the
material.
• In general, use DBxK5 #11 ~ #18 according
to the material thickness. For knitted
materials, use DBxK23 #11 because its
rounded point prevents the knit thread from
breaking.

What Can the Machine Do?
Editing
Enlargement/reduction is executed ahead of rotation. When an embroidery
pattern is so set to be rotated by 90˚ and then enlarged by 2 times in the X-axis
direction, the X-axis enlargement is executed first and rotation by 90˚ is executed
afterwards. Therefore, a pattern is enlarged by 2 times at the sewing point.
