Horizontal Directional Drill Maintenance Instructions

1. When using a new drill pipe, it should be ensured that the screw thread of the front section of the drill bit (protecting the shaft head) is also new. A drill bit with a broken thread can easily damage the thread thread of the new drill pipe, resulting in water leakage, snapping, and loosening etc.

2. When using a drill pipe for a drilling operation, you should first "grind a new button", which includes applying thread oil first, then tightening it with all your strength with a drill, then opening the button, and then applying thread oil and then opening it , so repeated three times, can avoid new rod wear and buckle.

3. Keep the drill pipe in a straight line between the ground and the ground as much as possible. In this way, it can avoid the force on the side of the threaded part and cause unnecessary wear and tear, or even skip the buckle.

4. Slowly tighten the buckle to reduce overheating and wear.

5. Every time you buckle up, you must tighten it with full torque, and always pay attention to whether the clip is in good condition.

6. Shorten the distance from the drilling rig to the entrance of the ground, because if the drill pipe lacks support, it will easily bend and deform when the drill pipe is pushed forward, resulting in a shortened service life.

7. Keep the entrance angle as small as possible, and slowly change the angle according to the safety requirements of the drill pipe.

8. Do not exceed the maximum bending radius of the drill pipe, and pay special attention to the angle change when drilling into a horizontal section and when drilling out.

9. Keep using drill pipes in turn, avoid using fixed drill pipes for guiding and pulling back, and you must take turns to avoid excessive wear and tear.
