The engine is the heart of the excavator, if the engine can’t start, then the whole excavator will also be unable to work due to the lack of power source. And how to the engine can not start this problem for a simple check, so as to reawaken the engine’s powerful power? To introduce you to a few common engine can not start the fault and the solution, to help you in the future use of equipment in the process can quickly solve the problem.
1. Circuit Check
First check the electric circuit. Circuit failures resulting in a failure to start the car will mainly appear to unscrew the ignition switch, no response or the starter motor speed is too low, the digger will feel powerless.
Solution: First check the battery pile head, clean the battery pile head, and then tighten the pile head screws, if possible, you can use the voltage meter to measure the battery voltage. If the battery is not faulty the next step is to check the wiring, check the wiring along the battery once, and observe whether the connector is loose or the wiring is broken.
2. Fuel Circuit Check
If the circuit check is completed and no faults are found, it is recommended that you then check the engine oil circuit. If there is a problem with the oil circuit, you can hear the starter motor turning strongly and the engine rotating, and the engine is a normal mechanical friction sound.
Solution: 1. Whether the fuel is sufficient
2. Whether there is water in the oil-water separator
3. Engine exhausts air
3. Fuel Tank Check
First, check if there is oil in fuel tank. Second, there are many owners who are not accustomed to draining to draining the oil-water separator every day. In case the oil used is not of high quality, the engine may not start due to excessive diesel water. So you have to unscrew the drain bolt at the bottom of the oil-water separator. Finally, to shoot the air in time, most excavators hand oil pump installed in the oil-water separator above the chapter, loosen the hand oil pump next to the bleeder bolt, press the hand oil pump by hand until the bleeder bolt out of all the diesel fuel, and then the bleeder bolt out of all the diesel fuel, and then the bleeder bolt to tighten the completion of the work of the air emissions.
Solution: Diesel engine mechanical failure is less likely to occur, but does not rule out thee occurrence of cylinder pulling, burning tile, or even pounding the cylinder, if it is the cause of mechanical failure, it is recommended to directly find a professional maintenance personnel for repair.
Through the above three steps of the simple engine judgment methods, can be a general engine failure simple judgment and solution. But some other complex problem, or need to have professional knowledge of the maintenance personnel to check and repair, so as to ensure that the engine can be the best working condition to run, to ensure that the equipment is reliable and efficient operation.
