One,A proper use of dredging boat
1, before starting the first of the entire mechanical drive system and machine oil checked, and then start the pull back conveying diesel engine, with the pull clutch, start engine, slowly moving loose clutch, the speed adjusted properly. Then launch diesel bucket front zipper.
2, two diesel engine after starting. The speed raised the need for speed. Then release the brake arm. Slowly it down, other than the sand hopper 2/3, to stop decentralization, until 1/3 and funded under the arm. When the big arm and the water into a 45 degree angle (5 meters), should stop lever. Then how much sand in the hopper with traction Control, when forward to see how much sand in the bucket and fixed, forward and backward to be flexible in case of mechanical sand cave strenuous work or pull to loosen the rope, the ship backward until it stops digging. In case of large stones under water or mud, the ship will be severe vibration phenomenon and then immediately filed dredging arm, then avoid obstacles.
Two, on time maintenance
1, each time you use it, you should check the tightness of the screws in each part, and often add some lubricating oil

3, when not in use, the ship stops, tied in a strong place, to avoid flooding the ship washed away, resulting in unnecessary losses
4, regular inspection of the engine, to prevent problems in the replacement parts in the time to stop, otherwise there may be casualties
5, dredging vessels should promptly carry out clean after use, so as to ensure the equipment continues.
Three, choose the regular manufacturers, choose suitable for their construction conditions of dredging ship accessories.
