11. Replenishing the designated places with grease
When the sewing machine has been used for a certain number of times of sewing, error code No. E220
is displayed on the operation panel at the time of turning ON the power. This display informs the opera-
tor of the time of replenishing the designated places with grease. Be sure to replenish the places with the
grease below. Then call the memory switch No. 245 and set it to "0" with the RESET key.
Even after the display of the error No. E220, when the RESET key is pressed, the error is released, and
the sewing machine can be continuously used. Afterwards, however, the error No. E220 is displayed ev-
ery time the power is turned ON.
In addition, when the sewing machine is used further for a certain period of time after the display of error
No. E220, the error No. E22 is displayed and the sewing machine fails to operate since the error cannot
be released even when the RESET key is pressed.
When the error No. E22 is displayed, be sure to replenish the designated places below with grease.
Then start up the memory switch and set No. 245 to "0" with the RESET key.
