4. Technical Specifications Decoded

The right technical settings elevate stitch quality. Use precise calibration and verified electrical specs to keep production smooth.

4.1 Needle Positioning Calibration

Seal hole methodology:

• Apply a seal on the needle plate hole and rotate the upper axis to 302–303 degrees. As the needle bar descends, confirm tip alignment with the seal hole.
• HCS2: check 1st, 4th, and 7th needles. HCD2: check 1st, 8th, and 15th needles.

Positioning plate assembly:

• The lower rail should center between bearings; fine-tune by rotating the upper shaft until the needle lands dead-center.

Backlash and clearance:

• Backlash adjustment removes play between rail and bearings.
• Always verify needle-shuttle hook clearance to prevent skips or breaks.

Rotary hook timing:

• Adjust the hook’s rotation relative to the needle so the thread is captured at the correct moment.
• After any needle position change, recheck rotary hook timing.

4.2 Electrical System Configuration

Voltage and power:

• HCD3E-1501-40 runs on single-phase 100–120V or 200–240V. Match local supply to requirements.

Speed control:

• Max speeds: tubular 1,200 rpm; caps 1,000 rpm. Low-speed mode allows 200 rpm for delicate work.

Control box features:

• USB or LAN transfers, PCMCIA memory card support, and LCD with speed, stitch counts, and alarms.

Safety:

• Only trained personnel should access electrical components. Heed error alerts to prevent downtime.
