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 voltages 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 high-
frequency welders.
Sources of strong electrical noise may cause prob-
lems 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 prob-
lems 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 for-
mation 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 52 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
foot switch is depressed by mistake, which could
result in injury.
Hold the machine head with both hands when tilting it
back or returning it to its original position.
Furthermore, after tilting back the machine head, do
not push the face plate side or the pulley side from
above, as this could cause the machine head to
topple over, which may result in personal injury or
damage to the machine.
Be sure to connect the ground. If the ground connec-
tion is not secure, you run a high risk of receiving a
serious electric shock, and problems with correct
operation may also occur.
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.

3-13. Installing the belt cover
1. Loosen the screw (2) of the upper cover (1).
2. Insert the belt cover (3) in the direction of the arrow, and
then secure it with the screw (2) and the two screws (4).
Check that the cords do not get clamped by the belt cover
at this time.
* It is not necessary to remove the belt cover (3) when
tilting back the machine head.
3-14. Installing the foot switch
1. Insert the connector of the foot switch (3) into the connector (2) of the control box (1).
2. Install the foot switch (3) to the work table leg (12) with foot switch support plate A (4), foot switch support plate C (5), the
bolt (6), spring washer (7), flat washer (8), bolt (9), spring washer (10) and flat washer (11) as shown in Figure A.
If foot switch support plate B (13) is used in a back-to-front position, it can be used as shown in Figure. B.
1. Remove the screw (14) and rubber plug (15).
* Note that the spring (16) will come out when the screw (14) is removed.
2. Turn foot switch support plate B (13) back to front, and then install it with the bolt (17), spring washer (18) and flat washer
(19) as shown in Figure. B.
Note:
If using the foot switch without installing it to the work table leg, move the foot switch at least 10 mm away from the leg. If
the foot switch is not fully in contact with the work table leg when the foot switch is used, for example, if it is just hooked
loosely onto the work table leg, it may cause the sewing machine to operate incorrectly.
If using the optional two-pedal foot switch, change the setting of DIP switch A on the oreration panel while referring to
"Setting the presser mode" on page 45.
