Newlong NP-7A User Manual
1. Preparation Before Starting
Before using the machine, follow these steps to ensure a smooth operation:
- Place the machine on a stable surface or hold it securely in hand for portable use.
- Oil the whole area through which the thread passes. It will remove the anti-corrosive layer from the machine.
- Verify the threading path and check the thread tension. Incorrect threading can result in uneven stitches.
- Check the needle setting & inspect the motor and power cord for any damage or loose connections.
- Make sure that the automatic oiling system has lubricated all moving parts. So, the machine can run smoothly.
- Double-check that the supply voltage is in accordance with machine specification.
Now, your machine is ready to start working.
2. How to Operate?
Using the Newlong NP-7A is straightforward & simple. Because most of the functions are in-built and you just have to operate it.
- Connect the machine to a suitable power source (220V).
- Place your index finger on the switch button located on the handle.
- Insert the open end of the bag between the presser foot & Feed Dog.
- Hold the bag firmly with one hand and operate the power switch with the other.
- Run the machine and hold the bag still. Don’t pull it back.
- Guide the bag along the stitching path. Keep consistent speed and alignment for a clean & secure closure.
- After closing, cut the thread. Leave at least 3cm thread to prevent loosening.
3. Adjustments in Newlong NP-7A
For optimal performance, you can adjust the machine’s function according to your needs. The following adjustments are allowed in it:
Adjustment | How to Adjust |
Stitch Length | Use the adjustment knob to modify the stitch length based on the bag material and desired seal strength. |
Thread Tension | Adjust the tension dial for even and secure stitches. Test on scrap material to confirm settings before sealing actual bags. |
Clearance | Clearance can be adjusted by the position of the needle and looper via the screw of the looper rocker. |
Presser Foot Pressure | Take out the needle bar guard and loosen the screw of the presser bar. It balances the presser foot pressure to hold the bag firmly without damaging it. |
Position of Feed Dog | When installing a new feed dog, ensure it is 2.8 mm above the throat plate by tightening the fixing screw. |
Always remember to disconnect the electric cord before making any adjustments.
