5. تعليمات التشغيل
Follow these steps for effective and safe use of your automatic center punch:
- تحضير قطعة العمل: Ensure the material you intend to mark is stable and securely placed on a flat, sturdy surface.
- ضع طرف الإصبع: Carefully align the tungsten carbide tip of the center punch precisely at the desired marking point on the workpiece.
- تطبيق الضغط: While holding the punch firmly and vertically, apply downward pressure on the body of the punch. The internal spring mechanism will compress until it reaches its trigger point, at which time it will release, creating a sharp, precise dimple on the surface.
- تحقق من العلامة: Lift the punch and inspect the created dimple. If a deeper or lighter mark is required, adjust the impact force as described in Section 6.
- الاختبار الأول: It is recommended to test the punch on a scrap piece of the same material or an inconspicuous area of your workpiece to determine the appropriate impact force setting before making final marks.

6. Adjusting Impact Force
The ENGINEER TZ-14 features an adjustable impact force mechanism, allowing you to customize the strike strength for different materials and desired mark depths.
- حدد موقع knurled cap at the top end of the center punch.
- ل يزيد the impact force, turn the cap clockwise. This compresses the internal spring more, resulting in a stronger strike.
- ل ينقص the impact force, turn the cap counter-clockwise. This loosens the internal spring, resulting in a lighter strike.
- Always test the adjusted force on a scrap material before applying it to your final workpiece.
