11-3. Applying grease

[When "GU" appears ... when using the control box panel]

Wait at least 5 minutes after turning off the power switch and disconnecting the power cord from the wall outlet

before opening the face plate of the control box. Touching areas where high voltages are present can result in

severe injury.

If "GU" flashes in the stitch number display (1) on the control box panel when the power switch is turned on, it indicates that it

is time for grease to be applied. (The sewing machine will not operate at this time, even if the treadle is depressed.)

Apply grease as required, while referring to the following for details.

1. Press the start backtack key (3).

2. The "GU" in the stitch number display (1) will stop flashing and disappear, and sewing will be possible when the treadle is

depressed.

(The power indicator (2) will flash.)

NOTE

・ "GU" will appear each time the power is turned on until you apply grease and reset the notification by carrying out the

reset procedure on the following page.

・ If you continue to use the sewing machine after the "GU" notification appears without applying grease (or without

carrying out the reset procedure), "-0" will appear in the stitch number display (1) after a certain period of time and the

sewing machine will be forcibly prevented from operating for safety reasons.

If this happens, apply grease and carry out the reset procedure.

* If you continue to use the sewing machine after carrying out the reset procedure but without applying grease,

problems with the sewing machine may result.

Use Brother-specified grease (SA7300-001).
