2. Notes on safety
DANGER
Wait at least 5 minutes after turning off the power switch and disconnecting the power cord from the wall outlet
before opening the face plate of the control box. Touching areas where high voltage are present can result in
severe injury.
CAUTION
Environmental requirements
Use the sewing machine in an area which is free
from sources of strong electrical noise such as highfrequency welders.
Sources of strong electrical noise may cause problems with correct operation.
Any fluctuations in the power supply voltage should
be within ±10% of the rated voltage for the machine.
Voltage fluctuations which are greater than this may
cause problems with correct operation.
The power supply capacity should be greater than
the requirements for the sewing machine’s electrical
consumption.
Insufficient power supply capacity may cause
problems with correct operation.
The ambient temperature should be within the range
of 5°C to 35°C during use.
Temperatures which are lower or higher than this
may cause problems with correct operation.
The relative humidity should be within the range of
45% to 85% during use, and no dew formation
should occur in any devices.
Excessively dry or humid environments and dew
formation may cause problems with correct operation.
Avoid exposure to direct sunlight during use.
Exposure to direct sunlight may cause problems with
correct operation.
In the event of an electrical storm, turn off the power
and disconnect the power cord from the wall outlet.
Lightning may cause problems with correct operation.
Installation
Machine installation should only be carried out by a
qualified technician.
Contact your Brother dealer or a qualified electrician
for any electrical work that may need to be done.
The sewing machine weighs more than 56 kg. The
installation should be carried out by two or more
people.
Do not connect the power cord until installation is
complete, otherwise the machine may operate if the
treadle is depressed by mistake, which could result
in injury.
Use both hands to hold the machine head when
tilting it back or returning it to its original position. If
only one hand is used, the weight of the machine
head may cause your hand to slip, and your hand
may get caught.
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.
ii
HE-8000
All cords should be secured at least 25 mm away
from any moving parts. Furthermore, do not
excessively bend the cords or secure them too firmly
with staples, otherwise there is the danger that fire or
electric shocks could occur.
Install the belt covers to the machine head and
motor.
If using a work table which has casters, the casters
should be secured in such a way so that they cannot
move.
Be sure to wear protective goggles and gloves when
handling the lubricating oil and grease, so that they
do not get into your eyes or onto your skin, otherwise
inflammation can result.
Furthermore, do not drink the oil or eat the grease
under any circumstances, as they can cause vomiting
and diarrhoea.
Keep the oil out of the reach of children.
CAUTION
Sewing
This sewing machine should only be used by
operators who have received the necessary training
in safe use beforehand.
If using a work table which has casters, the casters
should be secured in such a way so that they cannot
move.
The sewing machine should not be used for any
applications other than sewing.
Attach all safety devices before using the sewing
machine. If the machine is used without these
devices attached, injury may result.
Be sure to wear protective goggles when using the
machine.
If goggles are not worn, there is the danger that if a
needle breaks, parts of the broken needle may enter
your eyes and injury may result.
Turn off the power switch at the following times,
otherwise the machine may operate if the treadle is
depressed by mistake, which could result in injury.
• When threading the needle
• When replacing the bobbin and needle
• When not using the machine and when leaving the
machine unattended
Do not touch any of the moving parts or press any
objects against the machine while sewing, as this may
result in personal injury or damage to the machine.
If an error occurs in machine operation, or if abnormal noises or smells are noticed, immediately
turn off the power switch. Then contact your nearest
Brother dealer or a qualified technician.
If the machine develops a problem, contact your
nearest Brother dealer or a qualified technician.
Cleaning
Turn off the power switch before carrying out
cleaning, otherwise the machine may operate if the
treadle is depressed by mistake, which could result
in injury.
Be sure to wear protective goggles and gloves when
handling the lubricating oil and grease, so that they
do not get into your eyes or onto your skin, otherwise
inflammation can result.
Furthermore, do not drink the oil or eat the grease
under any circumstances, as they can cause vomiting
and diarrhoea.
Keep the oil out of the reach of children.
Maintenance and inspection
Maintenance and inspection of the sewing machine
should only be carried out by a qualified technician.
Ask your Brother dealer or a qualified electrician to
carry out any maintenance and inspection of the
electrical system.
Turn off the power switch and disconnect the power
cord from the wall outlet at the following times,
otherwise the machine may operate if the treadle is
depressed by mistake, which could result in injury.
• When carrying out inspection, adjustment and
maintenance
• When replacing consumable parts such as the
rotary hook
Turn off the power switch before inserting or
removing the plug, otherwise damage to the control
box could result.
HE-8000
If the power switch needs to be left on when carrying
out some adjustment, be extremely careful to
observe all safety precautions.
Use both hands to hold the machine head when
tilting it back or returning it to its original position. If
only one hand is used, the weight of the machine
head may cause your hand to slip, and your hand
may get caught.
Use only the proper replacement parts as specified
by Brother.
If any safety devices have been removed, be
absolutely sure to re-install them to their original
positions and check that they operate correctly
before using the machine.
Any problems in machine operation which result
from unauthorized modifications to the machine will
not be covered by the warranty.

• This is effective for preventing the material from getting stuck in the needle hole when sewing the rear
tack, which can happen when using lightweight materials.
(An offset is used so that the stitches do not overlap when sewing the reverse zigzagging for the rear
tack.)
* Reducing the number of front tack stitches is effective in preventing the material getting stuck at the
front tack.
* Using a needle plate with a small needle hole (1.2) as well can also help in preventing the material
from getting stuck.
3. Saw-shape
• This is effective for preventing dimples in the rear tack, without the need for underlay sewing.

Zigzag underlay stitch
1. Underlays sewn together
• This type of underlay pattern is used for resewing if the knife has operated before the seam has been
formed, such as when sewing is complete without the upper thread breaking even though the lower
thread has run out. It is particularly useful for sewing up the hole made by the knife beforehand at
times when zigzag stitches do not hold properly.
• The pile of fluffy fabrics is pressed down before sewing, so that the buttonhole finish looks more
attractive.
2. Saw-shape underlay
• This type of underlay is useful for stretch materials to prevent them from stretching.
• It is useful for preventing dimples from forming during bar tacking. Radial-type buttonholes are useful
for preventing dimples.
• It is also useful for strengthening the buttonholes to stop the seam from unravelling, which can often
happen with materials with coarse weaves.
3. Rectangle underlay
• This type of underlay is useful for stretch materials to prevent them from stretching.
• This is effective in preventing seams from unravelling in materials which appear not to have a very
coarse weave. It also serves to reinforce the buttonhole.
• If the seam is hidden and the seam width seems small, you can sew 2 - 3 rectangle underlays to make
the material look more voluminous.
• Underlays such as (1) to (9) in the illustration can be sewn in slightly different positions by changing
the setting value for parameter No. 50 (underlay offset) so that the seam does not become too stiff and
to further increase the feeling of volume.
4. Zigzag underlay stitch
• This is particularly effective in preventing seams from unravelling in materials which appear not to
have a very coarse weave. It also serves to reinforce the buttonhole.
(If parameter No. 58 - Zigzag width [Dimension A in the illustration] is set to about 0.4 mm, the zigzag
underlay stitches will be even stronger than other underlay stitches.)
* If parameter No. 58 is set after saw-shaped underlay stitches or rectangle underlay stitches have been
set, zigzag underlay stitches will only be sewn for the first cycle of underlay stitching.)
NOTE:
When sewing underlays, the number of bar tacking stitches will increase, so that thread breakages or broken
needles may occur. To avoid such problems, reduce the number of underlays or drop the sewing speed.
* When underlays are sewn together, the order of sewing is underlays sewn together → saw-shape
underlays → rectangle underlays.

5. OPERATION
5-4-6. Cutter operation
The cutter operating pattern can be selected from the following four patterns.
• Center knife operation, where the cutter operates when sewing of the buttonhole is complete
• Rear knife operation, where the cutter operates when sewing of the buttonhole is complete and the
material is fed so that the cutter is near the front tack
• Front knife, where the cutter operates before the final cycle of zigzagging stitches is sewn
• A combination of front knife and center knife

Because the needle and knife positions are separated by 2.2 mm as shown in the illustration, the
distance between the edge of the front tack and the
edge of the buttonhole cannot be set to less than 2.2
mm. In other words, if the knife Y space (A) is set to
0.5 mm, the front tack length (B) cannot be set to
less than 1.7 mm. If you would like the front tack
length to be less than 1.7 mm, the cutter can be
made to operate after sewing and feeding are
complete.

2: Front knife (Not available for single cycles. Only available when sewing two or more cycles.)
• This is used in cases such as when the rough edges of the material after cutting are hemmed by the
buttonhole stitches.
The cutter operates before the left zigzag stitch of the last cycle is sewn.
3: Front knife + Center knife
(Not available for single cycles. Only available when sewing two or more cycles.)
• This is used in cases such as when the rough edges of the material after cutting are hemmed by the
buttonhole stitches.
It can also be used if the rough edges of the material block the buttonhole after the left and right zigzag
stitches have been sewn.
The cutter operates before the left zigzag stitch of the last cycle is sewn, and then operates again after
the right zigzag stitch is sewn.

thread scissors (3) and the tip of the opening cam (2) is approximately 0.5 mm when the upper thread
scissors (3) are closed.
If you would like the scissors to start opening earlier, make the distance smaller. However, if the distance
is too small, check that the work clamp does not touch the rising section (C) of the upper thread scissors
(3) of the opening cam (2) when it is lowered and prevent the upper scissors (3) from opening.
* Apply grease to the inclined face (D) of the opening cam (2).
<Scissors fully opening timing adjustment>
1. Loosen the screw (5), and then adjust the support plate (8) so that the back plate (6) and the cam (7)
overlap by approximately 1.0 – 1.5 mm.

DANGER
Wait at least 5 minutes after turning off the power switch and disconnecting the power cord from
the wall outlet before opening the face plate of the control box. Touching areas where high voltages
are present can result in severe injury.
If a malfunction should occur with the sewing machine, a buzzer will sound and an error code will appear in
the display window.
Follow the remedy procedure to eliminate the cause of the problem.
For errors which do not require the power to be turned off (i.e. errors which can be reset), two short beeps
will sound. For error E-02, three short beeps will sound.
For errors which require the power to be turned off (i.e. errors which cannot be reset), a single long beep will
sound.
