2. Safety Instructions
Always follow basic safety precautions when using electrical appliances to reduce the risk of fire, electric shock, or injury to persons.
- Read all instructions before using the machine.
- Keep fingers away from all moving parts. Special care is required around the sewing machine needle.
- Always switch the sewing machine off when making any adjustments in the needle area, such as threading the needle, changing the needle, threading the looper, or changing the presser foot.
- Never operate the machine with any air openings blocked. Keep ventilation openings of the sewing machine and foot controller free from the accumulation of lint, dust, and loose cloth.
- Do not use outdoors.
- Do not operate where aerosol (spray) products are being used or where oxygen is being administered.
3. Getting Started (Setup)
3.1 Unpacking and Initial Inspection
Carefully remove the machine from its packaging. Ensure all accessories listed in Section 9 are present. Place the machine on a stable, level surface.
3.2 Power Connection
Connect the power cord to the machine and then to a suitable electrical outlet. Ensure the machine's power switch is in the 'OFF' position before connecting.
3.3 Threading the Machine
The SINGER HD0500S features an Easy View Threading system with color-coded thread paths and an innovative Lower Looper LED light for enhanced visibility, making threading more convenient.
- Raise the presser foot and turn the handwheel towards you to raise the needles to their highest position.
- Follow the color-coded guides for each thread (typically 2, 3, or 4 threads depending on your stitch choice).
- Utilize the Lower Looper LED light to illuminate the threading area for easier access.
- Ensure threads are seated correctly in all tension discs and guides.

3.4 Free Arm Setup
The machine features a removable accessory compartment that converts the flatbed into a free arm. This is ideal for sewing cuffs, pant hems, and other circular seams.
- To access the free arm, slide the accessory compartment off to the left.
- To return to flatbed sewing, slide the accessory compartment back into place until it locks.
4. Operating Instructions
4.1 Stitch Selection
The HD0500S offers 2, 3, and 4-thread configurations with 6 different stitch types. Refer to your machine's stitch guide for specific settings for each stitch type (e.g., overlock, rolled hem, flatlock).
4.2 Adjusting Stitch Settings
- Stitch Width: Adjust the stitch width dial to achieve the desired seam finish.
- Stitch Length: Adjust the stitch length dial (range 1.0 to 4.0 mm) to suit your fabric and project needs.
- Presser Foot Pressure: Adjust the presser foot pressure to ensure even feeding of various fabric types, from delicate sheers to heavy denim.
4.3 Differential Feed Adjustment
The differential feed system prevents fabric stretching or puckering on knits and sheers, and can also be used to create decorative ruffles.
- Turn the differential feed dial to adjust the ratio between the front and rear feed dogs.
- For normal sewing, set the dial to 'N' (normal).
- For stretching fabric, increase the ratio. For gathering or ruffling, decrease the ratio.

4.4 Sewing Speed
The HD0500S operates at up to 1,300 stitches per minute. Control the speed using the foot controller. Apply gentle pressure for slower speeds and increased pressure for higher speeds.
