2. Important Safety Instructions
When using an electrical appliance, basic safety precautions should always be followed, including the following:
- Read all instructions before using this sewing machine.
- Keep fingers away from all moving parts. Special care is required around the sewing machine needle.
- Always use the correct needle plate. The wrong plate can cause the needle to break.
- Do not pull or push fabric while stitching. This may deflect the needle, causing it to break.
- Switch the sewing machine off when making any adjustments in the needle area, such as threading the needle, changing the needle, threading the bobbin, or changing the presser foot.
- Always unplug the sewing machine from the electrical outlet when removing covers, lubricating, or when making any other user servicing adjustments mentioned in the instruction manual.
- Never operate the sewing machine if it has a damaged cord or plug, if it is not working properly, or if it has been dropped or damaged.
- Do not operate where aerosol (spray) products are being used or where oxygen is being administered.

3.2 Power Connection
Connect the power cord to the machine and then to a suitable electrical outlet. Ensure the machine is switched off before connecting to power.
3.3 Threading the Machine
Proper threading is crucial for good stitch quality. Follow these steps carefully:
- Winding the Bobbin: Place an empty bobbin onto the bobbin winder spindle. Guide the thread from the spool pin through the tension disc and around the bobbin several times. Push the spindle to the right and start the machine. Stop when the bobbin is full.
- Inserting the Bobbin: Open the bobbin cover. Insert the wound bobbin into the bobbin case, ensuring the thread unwinds in the correct direction (usually counter-clockwise). Pull the thread through the tension spring and out through the slot.
- Threading the Upper Thread:
- Place the thread spool on the spool pin.
- Guide the thread through the upper thread guide.
- Pull the thread down through the right channel.
- Guide it up through the left channel and into the take-up lever.
- Pull the thread down through the remaining guides to the needle.
- Thread the needle from front to back.

3.4 Needle and Presser Foot Installation
- Needle: Loosen the needle clamp screw. Insert the new needle with the flat side facing the back, pushing it up as far as it will go. Tighten the screw securely.
- Presser Foot: Raise the presser foot lifter. Attach the desired presser foot by aligning it with the presser foot holder and lowering the lifter until it snaps into place.
4. Operating Instructions
4.1 Basic Stitching
After threading, place your fabric under the presser foot. Lower the presser foot. Select your desired stitch pattern and length using the dials. Gently press the foot pedal to start sewing. Guide the fabric smoothly without forcing it.
4.2 Stitch Selection and Adjustment
The Singer M3335 offers 97 stitch applications. Use the stitch selector dial (refer to Figure 3.2) to choose your desired stitch pattern. Adjust stitch length and width as needed using the corresponding dials. Refer to the stitch chart on your machine for guidance.
4.3 Tension Adjustment
Correct thread tension is essential for balanced stitches. Adjust the upper thread tension dial (refer to Figure 3.2) if stitches appear too loose or too tight. A balanced stitch will have the upper and bobbin threads meeting evenly between the fabric layers.
4.4 Reverse Sewing
To secure the beginning and end of a seam, press and hold the reverse lever/button. The machine will sew backward. Release the lever/button to resume forward sewing.
4.5 Free Arm Sewing
Remove the accessory storage box to reveal the free arm. This feature is useful for sewing cylindrical items like cuffs, sleeves, and pant hems.
5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your sewing machine.
- Cleaning: Regularly clean lint and dust from the bobbin area, feed dogs, and tension discs using the provided brush or a small soft brush. Always unplug the machine before cleaning.
- Needle Replacement: Replace the needle frequently, especially after 8-10 hours of sewing or if it becomes bent or dull. A dull needle can cause skipped stitches and fabric damage.
- Oiling: Consult a qualified service technician for internal oiling if necessary. Modern sewing machines often require minimal user oiling.
- Storage: When not in use, cover the machine with its dust cover to protect it from dust and debris.
