CAUTION
Sewing
This sewing machine should only be used by opera-
tors who have received the necessary training in safe 
use beforehand. 
The sewing machine should not be used for any 
applications other than sewing. 
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. 
x When threading the needle 
x When replacing the needle and bobbin
x When not using the machine and when leaving the
machine unattended
If using a work table which has casters, the casters 
should be secured in such a way so that they cannot 
move. 
Attach all safety devices before using the sewing 
machine. If the machine is used without these 
devices attached, injury may result. 
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. 
Do not touch the motor cover during operation and for 
one hour after operation has finished, otherwise 
burns may result. 
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 un-
der 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. 
x When carrying out inspection, adjustment and main-
tenance
x When replacing consumable parts such as the ro-
tary hook
Turn off the power switch before inserting or 
removing the plug, otherwise damage to the control 
box could result. 
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 abso-
lutely 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.
