1) When there is soil and gravel in the excavator crawler, the angle between the excavating maneuver arm and the stick arm should be changed to keep it within 90°~110°; then the bottom of the bucket should be placed on the ground, One side of the crawler is suspended and rotated several times to make the soil or gravel in the crawler completely separate from the crawler, and then manipulate the boom to make the crawler fall back to the ground. Similarly, operate the other side of the crawler.
2) When the excavator is walking, choose a flat road or soil surface as much as possible, and should not move the machine frequently; when moving over a long distance, try to use a trailer to carry it, and try not to move the excavator around in a large area. ; It should not be too steep when climbing a steep slope. When climbing a steep slope, the route can be extended to slow down the slope and prevent the crawler from stretching and straining.
3) When the excavator is turning, the excavator arm and the stick arm should be manipulated to maintain an angle of 90°~110°, and the bottom circle of the bucket should be placed on the ground, and the crawlers on both sides of the front end of the excavator should be raised. , Make them 10㎝~20㎝ off the ground and control the one-side crawler to drive, and at the same time control the excavator to turn, so that the excavator can turn (if the excavator turns to the left, control the right crawler to walk, and then turn Turn the joystick to the right). If the goal is not achieved once, you can operate it again according to this method until the goal is achieved. This operation can reduce the friction between the crawler and the ground and the resistance of the road, so that the crawler is not easily damaged.
4) During the construction of the excavator, the apron should be leveled. When excavating stones with different particle sizes, the apron should be filled with crushed stone or powdered stone or soil with smaller particles. If there is no gravel, powdered stone or soil in the area, apply The car came from elsewhere. The leveling of the apron can make the excavator's crawler force evenly, and it is not easy to be damaged.
5) When maintaining the machine, check the tension of the track, maintain the normal tension of the track, and fill the track tensioning cylinder with grease in time. During inspection, first drive the machine a certain distance (about 4 meters) and then stop.
