What Should I do if the Excavator does not Start?

Feb. 04, 2020

How can we cope with the situation that the device cannot be started? Caterpillar Bucket Teeth Manufacturer tells everyone, don't worry if the equipment doesn't start normally, it's important to investigate the cause. So how to find the reason why the device cannot start?

1: Check diesel quality

First, check the quality of the diesel, put some oil out of the oil-water separator, and check the water content in the diesel. If the water content is too high, the machine will not start.

2: Check battery terminals and key fuses

Check whether the battery key switch is turned on or in place, check the battery voltage and whether there is any looseness or corrosion in the power pole, and whether the key fuse is blown or not in place.

3: Check neutral relay and hydraulic lock

After the switch is turned on, the display lights up and the motor is not working. You need to check whether the neutral relay is working. If the neutral relay is not working, we need to listen to whether the hydraulic lock has a ticking sound and whether the hydraulic lock is in place.

4: Check the starter motor

When the battery is working normally and the neutral relay is working normally, the black screen of the starter motor may be a failure of the starter motor.

5: Test battery voltage and engine speed

Open the "Performance" column in the display and we can see the battery voltage. After starting, you need to pay attention to the battery voltage (normally 18 volts or more) and the engine speed value (150 rpm) to start the device normally.

6: Check engine fuse

Damage to the engine computer board fuse will also prevent the machine from starting. Our company has Bucket Teeth for sale.

The removal of carbon can be accomplished by simple mechanical cleaning, which can be removed using a wire brush or scraper, but this method is not easy to clean and it is easy to damage the carbon on the surface of the part.
