Unplug when not in use.
The foot control regulates sewing speed.
If unsure about connection, consult a qualified electrician.
Press the main switch to I for power and light.

Threading the machine

Instructions from the manual

Wind the bobbin9 steps

Place thread and the corresponding spool holder on the spool pin.
Snap thread into the guide and wind clockwise around the bobbin-winder tension discs.
Thread the bobbin as illustrated and put it on the spindle.
Push the spindle right, hold the thread end and press the foot control.
Release after a few turns, release the thread and cut as close as possible to the spool, as the manual states.
Press again.
When full, the spool rotates slowly: release the pedal and cut thread.
Push the spindle left and remove.
While in winding position, the machine cannot sew and the handwheel will not turn; push the spindle left to sewing position to resume sewing.

Insert or remove the bobbin5 steps

Switch off before inserting or removing the bobbin and fully raise the needle.
Open the hinged cover, pull the bobbin-case tab and remove the case.
Hold it in one hand and insert the bobbin with thread running clockwise.
Pull thread through the slit and under the finger, leaving a six-inch tail.
Hold the case by its hinged latch and insert it into the shuttle.

Thread the upper thread9 steps

Switch off for needle threading.
Turn the handwheel toward you counterclockwise to fully raise the needle with the handwheel mark up.
Raise the presser foot to release the tension discs.
Lift the spool pin and place the spool on its holder, with the thread unreeling as illustrated; for small spools put the small side of the holder next to the spool.
Draw thread through the upper guide and pre-tension spring as illustrated.
Lead down the right tension channel and up the left while holding thread between spool and guide.
Pass right to left through the slotted take-up eye and down again.
Pass behind the thin wire needle-clamp guide, then thread the needle front to back.
Pull about six to eight inches to the rear beyond the eye and trim with the built-in cutter.

Complete upper-thread path and numbered detail panels. Switch off before threading; start with needle fully raised and foot up.

Raise the bobbin thread4 steps

Hold the upper thread in the left hand.
Turn the handwheel toward you counterclockwise to lower then raise the needle.
If raising bobbin thread is difficult, check that the hinged cover or removable table is not trapping it.
Gently pull the upper thread to bring bobbin thread through the needle-plate hole; lay both threads back beneath the foot.

Adjust and assess thread tension8 steps

Basic upper tension is 4.
Turn up a number to increase or down to reduce.
Loose straight-stitch tension needs a higher number; tight tension needs a lower number.
Normal zigzag / decorative tension leaves a little upper thread on the underside.
Factory-set bobbin tension needs no adjustment.
No setting suits every stitch, thread and fabric.
Balanced top / bottom stitches usually suit straight construction sewing; the manual states 90 percent of sewing is between 3 and 5.
Zigzag / decorative tension generally needs less than straight stitching; a little upper thread beneath the fabric improves appearance and reduces puckering.

Use the automatic needle threader6 steps

Switch off.
Raise the needle fully.
Pass thread around guide A.
Press lever B fully down so the threader swings to position C.
Pass thread in front of the needle around hook D from bottom to top.
Release lever B, then pull the thread through the needle eye.

Complete needle-threader movement, guide and hook. Switch off and fully raise needle before use.

Sewing

Instructions from the manual

Choose a stitch pattern4 steps

Turn the pattern selector dial in either direction to select a stitch.
Use the straight-line symbol for straight sewing and the zigzag symbol for zigzag.
For M3205 stretch patterns select S1 with the stitch-length dial and the desired pattern with the selector.
The shared manual’s S2 row applies only to M3500 / M3505, not M3205.

M3205 reverse sewing lever, stitch width dial, stitch length dial and pattern selector dial.

Sew a straight stitchView

Select straight stitch. Put fabric under the foot with its edge at the desired needle-plate seam guide. Lower the foot lifter, then press the foot control to sew.

Secure a seam with reverse sewingView

Press the reverse lever and sew a few reverse stitches to secure the beginning and end of a seam. Release it to sew forward again.

Remove finished workView

Turn the handwheel toward you counterclockwise until the take-up lever is highest and the needle begins descending. Raise the foot and remove work behind the needle and foot.

Cut the threadView

Pull threads beneath and behind the foot. Guide them beside the face plate into cutter B, then pull down to cut.

Sew a four-step buttonhole12 steps

Switch off for foot changes.
Remove the all-purpose foot and attach the four-step buttonhole foot.
Measure button diameter and thickness and add 0.3 cm (1 / 8 inch) for bartacks to obtain the buttonhole length; mark it on the fabric.
Place fabric with the foot mark aligned to the starting fabric mark; lower the foot so the marked center line aligns with the foot center.
Set density with the stitch-length dial in the illustrated buttonhole range.
Density varies with fabric: always test on the fabric you will use.
Follow the four-step selector sequence shown in the reviewed diagram, raising the needle before turning the pattern selector to the next step.
Do not sew too many stitches in steps2 and4.
Cut open with the seam ripper from both ends toward the middle.
Slightly reduce upper tension for better results.
Use stabilizer for fine or stretchy fabrics.
For stretch or knit fabric, heavy thread or cord is advisable; zigzag over it as illustrated in panel A.

M3205 four-step buttonhole: complete selector sequence, density range, fabric/foot alignment and cord example. Raise the needle before changing each selector position; test first.

Sew on buttons10 steps

Switch off for foot changes.
Fit the darning plate and change to the button sewing foot.
Set stitch length to 0.
Put the button and fabric beneath the foot as illustrated.
Select zigzag and width 3–5.
Turn the handwheel to check that the needle clears both holes; adjust width to the hole spacing.
Slowly sew about ten stitches.
Raise the needle out of the fabric, select straight stitch and sew a few securing stitches.
For a shank, put a darning needle on top and sew.
For four-hole buttons, sew the front pair first, push work forward and sew the rear pair.

Sew zippers and piping4 steps

Switch off for foot changes and fit the zipper foot, choosing its right or left attachment according to the sewing side.
Select the illustrated straight stitch.
To pass the tab, lower the needle into fabric, raise the foot and push the tab behind it; lower the foot and sew on.
A length of cord can also be sewn inside a bias strip to form a welt or piping.

Adjust stitch width and length8 steps

Maximum zigzag width is 5 mm; reduce it with the width dial.
Width increases from 0 to 5.
For M3205 straight sewing, 0 centers the needle and 5 moves it fully right; the left-position alternative belongs to the other explicitly listed models.
For zigzag, choose the zigzag pattern.
Density increases as length approaches 0; neat zigzag is usually at 2.5 or below.
Dense zigzag is satin stitch.
For straight sewing, select straight stitch; length decreases toward 0 and increases toward 4.
Longer length generally suits heavier fabric or thicker needle / thread; shorter length suits lighter fabric or finer needle / thread.

Choose stretch stitch patterns5 steps

The manual identifies stretch patterns by blue color.
Choose the desired pattern and select its S1 length indication; the M3205 selector has the S1 row, while S2 is limited to M3500 / M3505 on PDF19.
Straight stretch adds triple reinforcement to stretch and hardwearing seams, sewing two stitches forward and one backward.
Select the illustrated triple-straight pattern.
For ric rac, choose the illustrated pattern and width 3–5; it suits firm denim, corduroy, poplin, duck and similar fabrics.
