Applying Grease - JUKI LH-3500A series Instruction Manual

4-6. Applying grease
WARNING :
To protect against possible personal injury due to abrupt start of the machine, be sure to start the
following work after turning the power off and ascertaining that the motor is at rest.
To use the sewing machine in safety, periodically perform grease-up (standard is once in 2 to 3 years) to the
grease applying sections of the respective models with the cotton bar or the like. When using SC-920, when
the time of grease-up comes, the warning alarm sounds. When the alarm sounds, perform grease-up.
• Never lubricate oil to the grease applying places.
• When grease is applied more than is necessary, there is a fear that grease leaks from the thread
take-up lever cover section or the needle bar. So, be careful.
• Be sure to use the grease contained in JUKI GREASE A TUBE (Part No. : 40006323) supplied
with the machine head as accessories.
