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.

turning off the power.
If this is not done, the wiper may strike the needle,
which might cause the needle to break.
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 foot switch
is depressed by mistake, which could result in injury.
When carrying out inspection, adjustment and main-
tenance
When replacing consumable parts such as the ro-
tary hook
Disconnect the air hoses from the air supply and wait
for the needle on the pressure gauge to drop to “0”
before carrying out inspection, adjustment and repair
of any parts which use the pneumatic equipment.
If the power switch and air need to be left on when
carrying out some adjustment, be extremely careful to
observe all safety precautions.
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.
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.
