How many degrees does Kubota 30 excavator take glow plug to work?

Run the engine at low idle speed for at least 5 minutes to warm up the machine, and fully operate the handle to accelerate the warm-up of the hydraulic components. If the temperature is higher than 0℃, it takes about 15 minutes for the engine to warm up. If the temperature is lower than 0℃, it takes about 30 minutes for the engine to warm up. If the temperature is lower than-18℃ or the action is slow, extra time is needed to warm up the engine.

2. Run the engine at medium speed for 5 minutes and operate the bucket intermittently. The bucket cylinder is fully extended for no more than 10 second, and do not operate other actuators outside the bucket.

3. Run the engine at high speed for 5 minutes, and then repeat the previous step.

4. Circularly operate all actuators to achieve the preheating effect of the whole machine.

5. Observe the display and indicator light during operation.

Precautions for winter maintenance of excavators:

1, switch to low viscosity engine oil.

For colder areas, such as Xinjiang, it is necessary to consider replacing lower-grade engine oil in winter, such as SAE5W-40 engine oil (used at the ambient temperature of -30℃ to 40℃) or lower-grade engine oil; For warmer areas in the south, we can consider whether it is necessary to change different grades of engine oil according to the local actual situation.

Step 2 add antifreeze

When using the excavator in cold winter, the antifreeze content and the corresponding freezing point in the coolant should be checked in time. Ensure that the freezing point is 5℃ lower than the local minimum temperature. If the conditions are not met, please add antifreeze in time.

3. Switch to light diesel oil

Light diesel oil with low freezing point and good ignition performance should be selected for excavators in winter. Generally speaking, the freezing point of diesel oil should be 5℃ lower than the local minimum temperature in the current season. In the low temperature environment in winter, if the diesel oil with appropriate grade is not replaced in time, the fluidity of diesel oil will become worse and the viscosity will increase.

It is difficult to inject, which leads to poor atomization and combustion deterioration, which directly leads to the decline of power and economy of diesel engine. Even blocked the fuel pipeline, causing the machine to fail to start.

4, excavator butter

When selecting lubricating grease, several factors such as related working conditions, working conditions and working environment of the equipment are mainly considered. When the operating temperature is low, such as winter, the engine oil with low viscosity and thin viscosity should be selected; When the temperature is high, such as summer, oil with small evaporation loss and relatively thick should be selected.

5, excavator battery

Keep the battery fully charged and replace the battery with poor performance in time. In order to adapt to the working condition of large resistance when the engine is started in winter.
