3.2.1 Cleaning the machine
Before the head is packed, all the parts of the
machine are coated with preventive grease, which may
be hardened and contaminated by dust during long
storage and shippment. This grease must be removed
by clean cloth with gasoline.
3.2.2 Examination
The parts of the machine may be loose and
deformed after long distance transportation with jolt
though every machine is confirmed by strict inspection
and test before delivery. A thorough examination must
be performed after cleaning the machine. Turn the
balance wheel to check if these is running obstruction,
parts collision, uneven resistance or abnormal noise.
If any of these exist, adjustment must be made accor-
dingly before running.
3.2.3 Lubrication

places by arrow as shown in Fig.8 If the machine
continues in operation, it should be oiled not less than
twice per shift.
In lubrication, HA-8 sewing machine oil or HJ-7
