CHAPTER 7 TROUBLE SHOOTING …………………………………………………………… 7-1

The following set of safety rules categorized as DANGER, WARNING, and CAUTION indicates possibilities of
physical or property damages if not fully observed.
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.

DANGER
SAFETY RULES
DANGER : These safety instructions MUST be observed to be safe from danger when installing, delivering, or
repairing the machine.
WARNING : These safety instructions MUST be observed to be safe from machine injuries.
CAUTION : These safety instructions MUST be observed to prevent predictable machine errors.

Maximum 40

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.
[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.
[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 1 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 2. Machine Installation and Assembly for installation details.
1-2) MACHINE
INSTALLATION
CAUTION

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
The SWF Automatic Embroidery Machine is designed for applying
embroidery to fabric and other similar materials.
Pay careful attention to the WARNING and CAUTION stickers on certain
parts of the machine. Make sure to observe the following when operating
the machine:
1) Read thoroughly and fully understand the manual before operating the
machine.
2) 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.
3) Clear all persons from the machine before turning on the power.
4) 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.
5) Do not remove the safety cover on the pulley or shaft when the machine is
in operation.
6) 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.
7) Be sure the main switch is OFF before manually turning the main shaft.
8) Turn the machine off when threading needles or inspecting the finished
embroidery.
9) 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.
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.

and wait for 6 minutes.

2-1) INSTALLATION ENVIRONMENT
1) Temperature: ①0~40℃(32~104℉) when the machine is in operation
②-25~55℃(-13~131℉) when the machine is not in operation
2) Humidity: 45~90% (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.
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) Input voltage (to be adjusted when installing): 100V, 110V, 120V, 200V, 220V, 240V
2) Allowed range of voltage: within 10% of the voltage set
3) Electric capacity and voltage consumption: 600VA 400W
4) Insulation resistance: over 10M ohms (measured with 500V insulation tester)
[CAUTION]
Do not let moisture drops on the machine.
Provide 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).
Check the voltage supply where the machine will be installed.
Install the cable away from the operator’s work space to prevent accident or injury.
MACHINE INSTALLATION AND ASSEMBLY
Install your machine in an appropriate environment and with adequate electrical supply. Failure to follow the
directions may result in machine malfunction.

2-3) LEVELING THE MACHINE
The machine must be accurately leveled (especially front and back) to prevent the needle from moving out of
position.
1) Use the adjusting bolts installed at the four stands to level the machine (front, rear, left, and right). Use a level
gauge.
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.
③If the difference in heights of the four bolts is over 10mm, place spacers beneath the lower supporting bolts
to make the heights even.
2) The machine must be horizontally balanced on all four sides - front, rear, right, and left.
[CAUTION]
The level gauge does not measure accurately on a square pipe or a table.
[Fig.2-2]
3) Using the level gauge
Use a nut to fully fasten the adjusting bolts when the machine is leveled.

4) Using the body supporter [UH1506D-45]
Adjust the supporting bolt of the body supporter at the center of the machine after you are finished with
leveling. When adjusting the bolt, turn it until the bolt touches the level base and turn an additional quarter
round. Fasten the bolt with a nut.
[Fig.2-4]
Adjusting bolt
[CAUTION]
The supporter reduces the machine vibration.
Make sure not to adjust the bolt too high - it may lift the machine.
5) Using the auxiliary balance supporting bolt [UH1508-45, UH1512D-45]
Adjust the supporting bolt at the center of the machine after the balancing of the machine is finished. When
adjusting the supporting bolt, turn the bolt until it touches the level base and turn an additional quarter round.
Fasten the supporting bolt with a nut.
[Fig.2-5]
Adjusting bolt
[CAUTION]
The use of a supporting bolt for the auxiliary body supporter reduces the machine vibration and maintains
the balance of the machine.
Make sure not to adjust the bolt too high. It may lift the machine.
