In the context of the Kingtex manual, “Hit Verified” refers to the confirmation signal sent from the machine’s encoder and needle positioning sensor back to the central processor.

When you see “Hit Verified” on the LCD screen or within the manual’s troubleshooting section, it means:

If the machine displays an error stating “Hit Not Verified,” the production line stops immediately. This prevents defective products (missing stitches or thread breaks) from moving downstream.

Step 1: Enter Service Mode Power off the machine. Hold the P (Program) and + buttons simultaneously while turning the power on. The screen will flash S.ErV.

Step 2: Select Hit Sensor Test Using the arrow keys, navigate to parameter H-09. This is the “Needle Encoder Verification” menu. Press Enter.

Step 3: Manual Crank Slowly turn the handwheel toward you. Watch the LED bar on the control box. When the needle is exactly 3mm above the needle plate, you should hear a beep. This is the “Hit Ready” position.

Step 4: Set Verification Window In the manual, you will find a chart titled “Verification Window Tolerance.” Set parameter H-10 to 085 (default for standard fabric) or 092 (for heavy denim). This tells the machine how many micro-degrees of rotation count as a “verified hit.”

Step 5: The Dry Run Test Remove the thread and fabric. Run the machine at 500 RPM. The display must show HIT UER (Hit Verified) continuously. If you see HIT FALL (Hit Failed), repeat step 4.

Kingtex (typically distributed via Tacsew, Highlead, or specific regional dealers) maintains proprietary service manuals. Contact a distributor with your exact model number (e.g., SH-6000BL-7, SH-6000-UT).

Once you have the manual in hand, here is the procedural essence of what you will find. Perform this only with the machine unplugged.

Finding a legitimate, non-corrupted manual online is challenging. Many PDF repositories offer generic sewing guides that lack the specific "hit" timing diagrams for the SH 6000 series. Here is where to look:
