8. CLEANING AND INSPECTION

8. CLEANING AND INSPECTION
Turn off the power switch before carrying out cleaning, otherwise the machine may operate if the foot switch is
pressed 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.
Wait until the motor has cooled down before cleaning the air holes.
The motor may be hot immediately after it has been used, and it may cause burns if touched.

3. Clean all the dust and thread ends from around the driver (4), the top of the rotary hook thread guide and the shuttle
race.

8-2. Lubrication

Note 1: 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.
Note 2: Be sure to let the machine operate for a while after adding the oil.
Note 3: If there is no more oil on the felt of the shuttle race base, problems with sewing may result, so add oil to the felt
until it is slightly soaked.
Note 4: Use only specified Brother oil (Nisseki Mitsubishi Sewing Lube 10N; VG10) for the machine oil.
Lubrication points refer to "4. LUBRICATION".
