Replenishing The Designated Places With Grease - JUKI AMS-221EHL Manual

(5) Replenishing the designated places with grease

* Perform grease supplement when the errors below are displayed or once a year (either one which is
earlier). After performing grease supplement, call memory switch No. 245 and set the value to ì0î
with the reset key.
When the sewing machine has been used for a certain number or 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 operator 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 every 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. E221 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. E221 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.
(Caution) 1. After replenishing the places with grease, the error No. E220 or No. E221 is displayed
again unless the memory switch No. 245 is changed to "0".
2. Use grease tube (JUKI grease B Part No. : 40013640) supplied as accessories to replen-
ish the designated places below with grease. If grease other than the designated one is
replenished, damage of components will be caused.

of the sewing machine.
