SAFETY RULES
CHAPTER 1
ONLY TRAINED AND EXPERIENCED PERSONS, FAMILIAR WITH THE
RELEVANT SAFETY INSTRUCTIONS, SHOULD HANDLE THE MACHINE.
MAKE SURE TO FULLY OBSERVE THE FOLLOWING INSTRUCTIONS.
1) Using a Crane
Make sure that the crane is large enough to hold the machine. Use a nylon
rope of sufficient strength. Place a wooden block at either side of the
machine before tying the rope. The angle should be 40�or less. Make sure
that the rope does not touch the table.
※Make sure all persons and
obstacles are out of the way
of the moving equipment.

2) Using a Forklift
Make sure that size and weight of the forklift is sufficient to support the
machine. Use the pallet to place the machine so that its center is on the
forklift arm (see [Fig.1-2]). Lift the machine carefully so that the machine
does not tilt to either side.
[Fig.1-2]
Installation environment may incur machine malfunction or breakdown.
Make sure to meet the following conditions.
1) The foundation under the machine, i.e. table or desk, must be strong enough
to support the weight of the machine (approximately 3.5 ton).
2) Air conditioning can eliminate dust and humidity that can cause pollution
and corrosion of the machine. Make sure your machine is regularly cleaned.
3) Long exposure to direct sunlight can cause the paint of the machine to fade
or change of the machine shape.
4) Allow at least 50cm (20 inches) of space on each side of the machine for
convenient maintenance.
※Please refer to for installation details.

INSTALLATION
CAUTION
[WARNING]
Make sure to maintain the weight balance in machine deliveries,
especially when unloading the machine from a forklift or crane, in
order to prevent injury or machine damages.

1-3
Only SWF-trained and selected repair engineers should do repair work.
1) Turn OFF the power before cleaning or repairing the machine. Wait for 4
minutes so the machine electricity is completely discharged.
2) Do not change the settings or any parts on the machine without confirmation
from SWF. Such change may cause safety accidents.
3) Use only SWF parts when repairing your machine.
4) Replace all safety covers when you are finished with your repair.
1-4) REPAIR
DANGER
WARNING
The SWF Automatic Embroidery Machine is designed for applying
embroidery to fabric and other similar materials.
Pay careful attention to the and stickers on certain
parts of the machine. Make sure to observe the following when operating
the machine:
01) Read thoroughly and fully understand the manual before operating the
machine.
02) Dress for safety. Long and unbound hair, jewelry such as necklaces,
bracelets, and wide sleeves can get caught in the machine. Wear shoes with
non-slip soles.
03) Clear all persons from the machine before turning on the power.
04) Keep your hands or head away from the moving parts of the machine such
as needle, hook, take-up lever, and pulley when the machine is in
operation.
05) Do not remove the safety cover on the pulley or shaft when the machine is
in operation.
06) Be sure the main power is turned off and the power switch is set to OFF
before opening the cover of any electrical component or control box.
07) Be sure the main switch is OFF before manually turning the main shaft.
08) Turn the machine off when threading needles or inspecting the finished
embroidery.
09) Do not lean against the cradle or place your fingers near the guide grooves
of the frame.
10) The machine noise may exceed 85db when it is run at a maximum speed. It
is not higher than the standard level, but you may need earplugs or sound-
proof facilities for the operator and other workers.
CAUTIONWARNING
1-3) MACHINE
OPERATION
[CAUTION]
It takes about 10 minutes after turning off the main switch before the
electricity is fully discharged from X/Y main shafts and the drive box.

Fire or death may be caused by
high voltage electric shock.
Don’t open the cover except for
service man assigned by SWF.
When open the cover turn off
power and wait for 6 minutes.
Injury may be caused by
winding.
Be sure to turn off the power
before cleaning, lubricating,
adjusting or repairing.
Physical damage may be
caused by winding.
Don’t put your hands near the
arrow while the main shaft is
rotating
Physical injury may be caused
by crevice.
Don’t put your finger in a groove
on the table.
Injury may be caused by moving
needle.
Ensure that the machine is in a
stop condition before changing,
threading or rethreading of
needies or changing of needles.
Physical damage may be caused
by interposition.
While embroidery frame is running
according to the direction of
embroidery frame may be injured
your hands by gap between fixed
body and embroidery frame.
①Turn off the main power before rotating the
main shaft by hand!
②Do not remove covers during operation!
③Turn off the main power before opening
electricity-related boxes!

2-1
Install your machine in an appropriate environment and with adequate electrical supply. Failure to follow the
directions may result in machine malfunction.
2-1) INSTALLATION ENVIRONMENT
1) Temperature: 0 ~ 40℃(32 ~ 104℉) when the machine is in operation
－25 ~ 55℃(－13 ~ 131℉) when the machine is not in operation
2) Humidity: 45 ~ 85% (relative)
3) Grounding: Ensure the electricity is properly grounded.
4) Close any doors and windows near the machine to prevent direct light, dust, and humidity.
5) Foundation under the machine must be a sufficiently strong and flat concrete to support the weight of the
machine.
6) The machine must be installed and used in an industrial environment (Class A).
2-2) ELECTRICITY INSTALLATION
Check if the input voltage of the machine is in the right range of the voltage supply before installing or operating the
machine. The voltage required is as follows:
1) Allowed range of voltage: within ±10% of the voltage set
2) Electric capacity and voltage consumption: 3KVA, 1.4-1.6 KW
3) Insulation resistance: over 10M ohms (measured with 500V insulation tester)
MACHINE INSTALLATION AND ASSEMBLY
CHAPTER 2
[CAUTION]
①Do not let moisture drops on the machine.
②Provide air conditioning to control humidity and to prevent dust and corrosion.
DANGER
WARNING
Properly ground the machine to avoid the possibility of electric shock. Use three-wire
grounding (grounding resistance below 100 ohms).
①Check the voltage supply where the machine will be installed.
②Install the cable away from the operator’s work space to prevent accident or injury.
