How Do We Maintain Excavators in Summer

With summer just around the corner, maintaining an excavator becomes more critical than ever. Both the drivers and the machines are tested by the high temperatures and heat during operation. The high temperatures can cause various failures of excavators, leading to unnecessary downtime and repair expenses. However, by adopting proper maintenance skills, these problems can be avoided. By being mindful of the following tips and tricks, excavator drivers can reduce the frequency of small excavator failures and ensure smoother operation of their machines despite summer's sweltering heat.

To prevent detrimental effects, it is important to refrain from operating the excavator under high temperatures for extended periods. Similarly, it is advisable to refrain from using cold water to forcefully cool down the excavator.

To ensure safe operation of excavators, it is important to frequently check the efficiency of the braking system. Prolonged use of the brake can lead to excessive temperatures in the brake hub and brake pad, resulting in decreased braking performance. In such situations, it is recommended to immediately stop the machine to allow for cooling, rather than flushing with cold water. This can lead to air lock, which can make it difficult to start the engine after a few minutes of stopping. If the driver encounters resistance while driving, it is important to stop and cool down the machine and eliminate any faults in the braking system. By properly maintaining the braking system, we can reduce the risk of accidents and ensure safe excavator operation.

It is important to replace the antifreeze in your vehicle as recommended. Also, make sure not to mix different brands of antifreeze. Mixing different brands can cause unpredictable chemical reactions and potentially damage your engine. Therefore, it is always best to stick to the same brand of antifreeze throughout the lifespan of your vehicle. By doing so, you can ensure the proper maintenance of your engine and avoid costly repairs in the future.

Antifreeze isn't just for winter - it's a year-round necessity. With its unique combination of low freezing point and high boiling point, it ensures that the vehicle's cooling system stays in good condition no matter the season. By preventing the water from boiling in the warmer months, antifreeze helps avoid any potential damage that could arise from excessive heat. Furthermore, it typically comes with anti-rust and anti-corrosion properties, which help the cooling system last longer by slowing down the natural aging process. Additionally, antifreeze helps prevent scale build-up in the system, which can block the circulation pipe and negatively affect the engine. Authentic antifreeze can be used for up to 2000 hours, whereas regular antifreeze is only good for 1000 hours. It's important to not mix different brands of antifreeze, as they each have their own unique properties that shouldn't be combined.

3. Replace the hydraulic pressure in time

To ensure the smooth operation of a small excavator, it is crucial to perform regular checks on the hydraulic oil, return oil filter, and pilot filter. It is vital to note whether the filter elements are collecting copper and iron scraps. When using a crusher, the hydraulic oil's quality deteriorates at a faster rate and requires shorter replacement cycles. Never operate machinery under oil shortage conditions for extended periods. Additionally, it is important to remove any air pockets from the hydraulic system after replacing hydraulic oil or hydraulic components.

4. Pay attention to the use of diesel

It is important to select different brands of diesel for small excavators based on the ambient temperature. Remember to avoid mixing diesel with impurities, ash, or water as it can lead to premature wear of the fuel pump. Low-quality fuel with high paraffin and sulfur content can cause engine damage. To prevent water droplets from forming on the fuel tank's inner wall, ensure that it is filled with fuel after daily operation. Additionally, before daily operation, make sure to open the drain valve at the bottom of the fuel tank to remove any accumulated water. When the engine fuel is depleted or the filter element is replaced, it is crucial to exhaust the air in the pipeline. By following these guidelines, the equipment's performance and longevity can be preserved.

To prevent cylinder scuffing, it is important to avoid shutting down the engine immediately. One should pay close attention to the water temperature gauge and ensure that the water temperature is within the acceptable range before turning off the engine. This precautionary measure can help maintain the overall health and performance of the engine.

When operating an excavator, it is vital to monitor the water temperature gauge constantly. If it goes above 90°C, take action immediately. Park the excavator in a nearby shaded area and let it cool down at idle speed. Avoid shutting off the engine immediately to prevent issues such as cylinder seizure due to overheating inside the engine. After the temperature drops, check the fan belt's tension to ensure that everything is working correctly. Always prioritize safety when handling heavy machinery like an excavator.
