Changing the needle
The use of the Needle Inserter is recommended and prevents the needle from falling into the Feed Dog area.
(see page17)
The Needle Holder Screws must always be tightened, even if no needles are inserted, this prevents the
Needle Holding Screws from falling out because of vibration. Correctly inserted needles are not at the same
height.
NOTICE
Damage due to excessive tightening of the screws
The threads of the Needle Holder may be damaged. A repair by the Authorized bernette dealer is required.
> Do not overtighten the Needle Screws.
The Needle Holder can hold two needles. The machine is designed for needles of the ELx705 system. Needle
sizes between 80 − 100 are to be used for this machine. (see page35)
Prerequisite:
• The needles are in the top position.
