If oil is not added and the oil drops below this level, there is the danger that the machine may seize during
operation.
NOTE2: Be sure to let the machine operate for a while after adding the oil.
NOTE3: 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.
NOTE4: Use only specified Brother oil (Nisseki Sewing Libe 10) for the machine oil.
