3-12. Lubrication
CAUTION
Do not connect the power cord until lubrication has been completed, otherwise the machine may operate if the foot 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.
࡮ 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
Lube 10N; VG10> specified by Brother.
* If this type of lubricating oil is difficult to obtain, the recommended oil
to use is .
1. Hold the base of the nozzle of the accessory oil tank (1), and
use scissors to cut about half-way along the straight section
(A) of the nozzle.
2. Loosen and remove the nozzle, and then remove the seal
(2).
3. Tighten the nozzle.
4. Open the oil feeding pocket cover (3).
5. Insert the nozzle of the oil tank (1) deeply into the oil feeding
pocket (4), and then add lubricating oil.
6. Check that the oil level is between the upper reference line
and the lower reference line in the oil gauge window (5).
NOTE:
• When the oil level drops below the lower reference line in the
oil gauge window, be sure to add more oil. If the oil level drops
below the lower reference line, problems with operation of the
sewing machine such as seizing may occur.
• Do not add oil so that the oil level goes above the upper
reference line, otherwise the oil may spill out when the
machine head is tilted back
