3-14. Lubrication
CAUTION
Do not connect the power cord until lubrication is complete.
If the foot switch is depressed by mistake, the sewing machine might start operating and injury could result.
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. If the oil and grease get into your eyes or onto your skin, inflammation can result.
Furthermore, do not drink or eat the lubricating oil or grease. They may cause diarrhea or vomiting.
Keep the oil out of the reach of children.
The sewing machine should always be lubricated and the oil supply replenished before it is used for the first time, and also after
long periods of non-use.
Use only the lubricating oil <JX Nippon Oil & Energy Corporation Sewing Lube N10; VG10> specified by Brother.
* If this type of lubricating oil is difficult to obtain, the recommended oil to use is <Exxon Mobil Essotex SM10; VG10>.
1. Fill the arm-side oil tank with oil.
2. Fill the bed-side oil tank with oil.
NOTE:
Be sure to fill the machine with oil
when the oil level is down to about
one-third full in the oil sight glass. If the
oil drops below the one-third level,
there is the danger that the machine
may seize during operation.
3. Pour oil in through the two holes of
the shuttle race base assembly so
that the felt (4) is lightly moistened.
If it is difficult to add oil, you can also
remove the rubber plug (5) and pour
in the oil through the hole.
NOTE:
・ The two pieces of felt (4) should
normally project by 0 to 0.5 mm
from the hook race. Be careful not
to push in the felt (4) when
lubricating.
・ If there is no more oil on the felt
(4) of the shuttle race base
assembly, problems with sewing
may result.
