2. PREPARATION
2. PREPARATION
2-1. Installing the machine
―3 ―BAS-705
●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 205
kg. The installation should be carried out by
two or more people.
●Do not connect the power cord until installa
tion is complete, otherwise the machine may
operate if the start switch is pressed by mis
take, which could result in injury.
●Be sure to connect the ground. If the ground
connection is not secure, you run the risk of
receiving a serious electric shock.
CAUTION
●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.
●Avoid setting up the sewing machine near
sources of strong electrical noise such as high-
frequency welding equipment.
If this precaution is not taken, incorrect ma
chine operation may result.
1. Push the ON end of the lever qdown to secure
the caster w.
2. The machine can be moved by pushing down the
OFF end lever q.
3. Loosen the nut eand turn the adjusting screw
rto adjust the height of the base.
NOTE:
After adjusting, securely tighten the nut e.

cutting cylinder is in the lock position (flat-end
cutting).
■Changing to V-shaped cutting
1. Remove the q, set the knife stopper wto the posi-
tion shown in the illustration at left, and then re-tighten

2. PREPARATION
2-6. Lubrication CAUTION
―6 ―BAS-705
●Turn off the power switch before starting lubricating, otherwise the machine may operate if the start
switch 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.
1. Fill the arm-side oil tank with oil. 2. Fill the bed-side oil tank with oil.
3. Fill the oil tank at the side of the lower shaft module
base with oil.
2-6-1. Machine mechanism
NOTE ・Fill the machine with oil when the oil level is down to about one-third full in the oil sight glass.
If oil is not added and the oil drops below this level, there is the danger that the machine may seize
during operation.
・Be sure to let the machine operate for a while after adding the oil.
・Use only specified Brother oil (Nisseki Sewing Lube 10) for the machine oil.
