The role of the battery (battery) is to supply the short-term huge discharge current (300-500A) required for the starter motor. When the generator does not generate electricity, or the generator generates insufficient electricity at low speed and the generator is overloaded, it can supply power to the electrical equipment. It can also convert the electrical energy provided by the generator into chemical energy and store it, and then supply power to the electrical equipment.

1. When walking on the construction site, please try to place the travel motor behind the walking to reduce the squeezing of the sprocket.

2. The continuous walking time of the machine cannot exceed 2 hours. The walking time on the construction site should be minimized. If necessary, it is recommended to walk after a short stop in the middle.

3. Avoid raised hard objects when walking to avoid stress concentration on the track chain.

4. Confirm the tightness of the crawler, adjust the crawler tighter in soft places such as soil, and adjust the crawler looser when walking on stones. It is not good to have a crawler that is too loose or too tight. Too loose will cause the crawler to derail easily, and too tight will cause the chain sleeve to wear too quickly.

5. Check whether there are foreign objects such as stones in the crawler frequently, and clean them if there are.

6. When working on a muddy construction site, it is necessary to frequently idle to discharge the soil deposited in the crawler.

7. Try to avoid the excavator turning in circles on the spot.

8. Regularly check the rail guard and the rail guard welded under the guide wheel.

The maintenance frequency of the hydraulic pump is usually performed every 1000 to 2000 hours of operation or once a year according to the manufacturer's recommendations.

1. There must be enough starting speed. The high starting speed means less gas leakage in the cylinder, shorter heat transfer time of compressed air to the cylinder wall, less heat loss, and higher gas temperature and pressure at the end of compression. Generally, the speed is required to be above 100r/min.

2. The cylinder should have good sealing. This can further reduce the amount of leakage and ensure that the gas has sufficient combustion temperature and pressure at the end of compression. The compression pressure of the cylinder shall not be lower than 8_0_%_ of the standard value.

3. The engine is required to have appropriate clearance relative to the running parts and good lubrication.

4. The battery must have sufficient starting capacity and the technical condition of the starting circuit is normal.

5. The starting oil volume meets the requirements, the injection quality is good, and the injection advance angle meets the requirements.

6. Use fuel that meets the requirements
