(5) Grease-up procedures for the specified position
When sewing operation is repeated for a certain time period, Error Code No. E220 is displayed at the operation
panel when the power supply is turned ON. This error code is used for the indication of the grease replenishing time
for the specified parts. When you see this error code, replenish the grease specified below, without fail. After greas-
ing, call the memory switch No. 245 and set up “0” with the reset key.
Even after the display of Error Code No. E220, this error code can be canceled by pressing the reset key and the
machine can be used continuously. Since then, however, this Error Code No. E220 is displayed each time the power
supply is turned on.
When the sewing machine is used further for the specified time period after the display of Error Code No. E220,
Error Code No. E221 is then displayed. In this case, this error code cannot be canceled even though the reset key
is pressed, and the sewing machine cannot work anymore.
Therefore, when this Error Code No. E221 is displayed, replenish the grease, without fail, to the parts specified
below. Start the memory switch and set up the Memory switch No. 245 at “0” with the reset key.
Cautions: 1. If the memory switch No. 245 is not reset at “0” after the replenishment of grease, Error No.
E220 or No. E221 will be displayed again.
2. For the replenishment of grease to the parts specified below, use the attached Juki Grease B
(Part No. 40013640). If any grease other than the specified item is replenished, this can be
a cause of destruction of parts.
