In this community of shared destiny, Kyotechs shares information, resources and opportunities with suppliers, customers, technical partners and other relevant parties. In this way, the company can not only respond quickly to market needs, but also foresee and respond to industry challenges in advance. The success of our partners is our success. It is this concept of symbiosis and win-win that has established a good reputation for Kyotechs in the industry.

As a company focusing on excavator parts, Kyotechs' products cover hydraulic pumps, engine parts, electronic controllers, transmission system parts and other fields. These high-quality parts not only ensure the efficient operation of the excavator, but also play an important role in improving overall engineering efficiency and reducing equipment failures.

Kyotechs not only pursues commercial success, but also takes "becoming a happy person in the field of excavation equipment" as its vision, emphasizing the happiness and satisfaction of all stakeholders. This vision reflects the company's deep care for employees, customers and society.

For Kyotechs, customer satisfaction is an important criterion for measuring our success. The company has always been customer-oriented and provides high-quality products and a full range of services. Whether it is product quality, delivery speed or after-sales service, Kyotechs strives to do its best to ensure that every customer can enjoy an experience beyond expectations.

After the newly purchased battery is injected with the liquid with the appropriate specific gravity, it should be placed for 6-8 hours to allow the liquid to penetrate the plates. When the temperature of the liquid drops below 30℃, it can be charged for the first time. The initial charge should be carried out in two stages. The charging current in the first stage should be lower than 1/10 (one tenth) of the rated capacity of the battery, and the time is about 25-35 hours. When the voltage of a single cell rises to 2.4 volts, the current is reduced by half and the second stage is entered, which takes about 20-30 hours. When the electrolyte emits strong bubbles and the specific gravity no longer rises, the voltage of a single cell rises to 2.6-2.75 volts and remains unchanged for 2-3 hours, it means that the battery is fully charged. During charging, the temperature of the electrolyte will rise, exceeding 40℃ in summer and 35℃ in winter. Charging should be suspended and recharged when the temperature drops below 30℃ to prevent damage to the plates and separators.

Kobelco excavator maintenance tips 1: Cooling to prevent air blockage In high temperatures in summer, the engine is prone to air blockage due to high speed and difficult heat dissipation, which makes it difficult to start the engine after stopping for a few minutes. Once air blockage occurs, the excavator driver should stop the engine immediately to cool down and eliminate the fault.

Kobelco excavator maintenance tips 2: Observe the water temperature gauge at any time to prevent water shortage When driving in high temperature weather, always pay attention to checking the cooling water volume and the water temperature gauge. When water shortage is found, immediately idle the engine to cool down before adding water, and be careful not to open the radiator cap immediately to prevent burns.

Kobelco excavator maintenance tips 3: Prevent engine oil from deterioration Lubricating oil is easily diluted by heat, resulting in poor oxidation resistance, easy deterioration, and even causing faults such as burning of the bearing and the shaft. Therefore, the crankcase and gearbox should be replaced with summer lubricating oil, and the amount and quality of the lubricating oil should be checked frequently, and replaced in time.

Kobelco excavator summer maintenance tips 4: timely cleaning of engine surface oil If the external oil of the engine is too thick, it will affect the heat dissipation and bury the hidden danger of failure of various parts. You can use the high-pressure spray method to clean the engine parts with a cleaning agent that does not corrode the body parts.

Kobelco excavator summer maintenance tips 5: prevent the water tank water temperature from being too high In summer, the cooling water of Kobelco excavators evaporates and consumes quickly. You must add enough cooling water before leaving the vehicle, and check the water level frequently during work. For single-cylinder diesel engines without a water temperature gauge, always pay attention to the red mark height of the water tank float. If the float cannot be used normally, it should be repaired in time. If the boiling phenomenon occurs during work, do not add cooling water directly. Stop the work, slow down the generator, and slowly add cooling water after the water temperature drops to avoid cracks in the water tank when it is cold.

Kobelco excavator summer maintenance tips 6: Ensure the best oil supply time In summer, the oil supply time of Kobelco excavators should be adjusted. If the oil is supplied too early, the engine will make a knocking sound and sometimes reverse; the oil supply time should not be too late, otherwise the engine will work weakly.

1. The starter and flywheel teeth are not meshed well. The ring gear and the starter gear collide when starting the engine, causing tooth damage or single-sided wear of the teeth. If more than three teeth are damaged or worn seriously, it will be difficult for the starter gear and the ring gear to mesh.

2. Cylinder sticking. When the engine temperature is too high, the engine is stopped and the heat is difficult to dissipate. The piston ring at high temperature sticks to the cylinder and cannot start after cooling.

3. Crankshaft lock. Due to lubrication system failure or lack of oil, the sliding bearing rubs dry, which eventually locks the crankshaft and cannot start.

4. The injection pump plunger is stuck.
