Safety Regulations
The following safety regulations must be observed without fail: It is important to pay attention to the needle and knife
while sewing as these are potential sources of injury to fingers. Movements within the area of the needle, knife or
looper such as threading, changing needles or presser feet, or raising the knife, may only be done with the machine
switched off (power switch at “O”). When cleaning or lubricating the machine replacing the bulb or when sewing is
finished, machine should be disconnected from the electricity supply. All repair work, especially electrical repairs
(e.g. renewing the cable connection out by one of our authorized service agencies.
Please note:
Funlock 004 is not equipped with differential feed. All points relating exclusively to Funlock 004D are marked with

Preparing the machine
Thread cones/spools
The anti-vibration cone should be used with the wider edge
at the bottom on the spool holder pin when sewing with
cones.
Large spools
If large industrial spools are used, position the anti-vibration
cone upside down on the spool holder pin, i.e. with the wider
edge at the top.

holder pins and push the spool capon with the rounded side
downwards.

Using the machine
Two-step presser foot lifter
To raise the presser foot, raise the presser foot lever on the
rear of the machine, until it engages (A). It can be raised

more space between presser foot and stitch plate (B).
Changing the presser foot
• Turn power switch to “O”
• Raise the presser foot
• Turn handwheel towards you until needles are fully
raised.
Press the catch (C) to release the presser foot from the
clamp. Raise the presser foot to the highest position (B)
and remove the presser foot to the left. To attach the
presser foot, place it under the shaft. The groove in the
shaft should line up exactly with the presser foot pin
(D). Lower the shank and the presser foot will engage
automatically.

Needles can be inserted quickly and easily with the practical
brush-cum-needle inserter (A).
• Turn power switch to “O”.
• Turn handwheel towards you until needles are fully
raised.
• Lower the presser foot.
Using the small screwdriver, loosen the needle set- screws
and remove the needles (B).
Place right-hand needle, flat sides towards the back, into the
hole of the needle inserter and insert the needle as far as
possible into the needle clamp. Tighten the set-screw lightly
and then insert the left-hand needle in the same way and
tighten both setscrews (C).
Needle and machine

(household needles). These should be purchased when
replacement needles are required. Use needles no. 70 – 90 on
your Bernette.
Raising the upper knife
• Turn the power switch to “O”
• Turn the handwheel towards you until needles
are fully raised.
• Open looper cover.
Press the upper knife holder (D) to the right. Turn the knob
clockwise (E) until the knife is in the position illustrated (F).
