Usage Features
Installation and Assembly:
- Machine Delivery: Requires trained personnel, safety shoes, and proper handling. Forklifts should be of sufficient size and weight capacity, with the machine's center placed on the forklift arm. Weight balance must be maintained to prevent injury or damage.
- Machine Installation: Requires a strong foundation (table/desk), air conditioning to control dust and humidity, and protection from direct sunlight. A minimum of 50cm (20 inches) space around the machine is recommended for maintenance.
- Leveling: The machine must be horizontally balanced using adjusting bolts on the stand. For stands, casters should be raised above floor level. If height differences exceed 10mm, spacers should be used.
- Peripheral Devices Assembly:
- Tubular to Border Frame Conversion: Involves disassembling tubular arms and fastening the border frame to the connection plate.
- Table Assembly: Fix supporter A and B to the body, then place and fix the table to supporter A, adjusting height to match the bed cover top. The table should not be higher than the needle plate by more than 0.5mm for board frame work.
- Frame Assembly: Loosen fixing screws of the tubular frame, insert into the groove of the mounting plate, and fasten. For border frames, remove the tubular frame attachment plate, assemble the table, and then insert the border frame connecting plate into the X-transfer frame.
- Upper Thread Stand Assembly: Involves assembling the spool plate, support, and thread holders.
- Operation Box Assembly: Involves mounting the operation box and connecting the power cable.
Basic Machine Operation:
- Power Operation Switch and Emergency Stop Switch: Main power switch is on the side, power button and emergency stop switch are on the front. Raise the main power switch, then press the power button to start. Press the emergency stop switch for immediate stops.
- Emergency Stop Operation and Release: Press the emergency stop switch to stop. Turn it right to release, then press the power push button to restart.
- Lamp on Thread Tension Adjustment Board: Toggle switch turns on the indicator lamp. Use the STOP button to move the frame back after a thread break. Press the toggle switch twice to move the frame back when no thread break has occurred.
- Data Return Button: Returns the frame to the saved auto-stop position.
- Trimming Button: Activates the automatic trimming function.
- SAP Presser Foot Origin Position Move Button: Moves the SAP presser foot to its origin.
- SAP Presser Foot Ready/Lowering Position Move Button: Moves the SAP presser foot between ready and lowered positions.
- Upper Threading: Detailed steps for threading through the thread guide tube, threader, thread take-up, and needle.
- Lower (Bobbin) Threading and Tension Adjustment: Use cotton yarn (#80-#120). Insert bobbin into the bobbin case, pull thread through the guide, and trim to 3-4cm. Ensure the bobbin rotates clockwise when pulling the thread. Adjust tension using the nut on the tension spring; clockwise increases tension, counterclockwise decreases. Optimal tension is 25-35g.
- Changing the Needle: Ensure the needle is clear of the needle plate. Manually turn the hand lever to raise the needle. Hold the needle, loosen the screw with a flat-blade screwdriver, and remove.
START/STOP Switch Operations:
- Starting/Stopping Embroidery: Press START to begin, Hold START for "inching" (low-speed embroidery), Press STOP to stop.
- During Machine Stop: Press STOP to move frame backward in selected units. Hold STOP to move frame backward continuously. Press STOP again to stop backward movement.
- Forward Non-Stitching: Press START to move frame forward in selected units. Hold START to move frame forward continuously. Press START again to stop forward movement.
- Backward Non-Stitching: Same as "During Machine Stop."
- Other Work: Select function (e.g., solenoid test, thread break sensor test, manual trimming) and press START.
