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.
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.
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 in-
flammation 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.
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.
