Excavator, also known as excavating machinery, is an earth-moving machine that uses a bucket to excavate materials above or below the bearing surface and load them into a transport vehicle or unload them into a stockpile, which has become one of the most important construction machines in engineering construction. In use, reasonable maintenance is an effective means to extend the service life of the machine.

Daily inspection work is to ensure that the hydraulic excavator can maintain efficient operation of an important link in the long term, do a good job of the usual daily inspection work can effectively reduce maintenance costs.

1. 1.When the excavator is stopped, check carefully whether there is any loosening of the foot screws, bearing tile screws, gear meshing and lubrication in each part of the excavator, as well as whether there is any abnormal wear and damage to the bearings, power unit, control system, brake, gearbox, crawler plate, foundation parts, cables, wire rope, bucket teeth and other parts.
2. 2.During operation, pay attention to the operation of the motor, mechanical transmission and braking system, control system, cooling fan, lighting and signals, etc. for any abnormalities, in the inspection of various problems to be found in time, timely treatment.
3. 3.For the newly installed excavator, before the trial run must be filled with oil in all parts, and in the first week of work to do the shift to check the lubrication; for long-term suspension of the excavator, before use must do the original old dry oil all squeezed out. Good lubrication can reduce the operation of mechanical wear and tear and failure, lubrication must be strictly in accordance with the period specified in the excavator manual, the amount of oil, lubricant type.
4. 4.The filter element plays the role of filtering impurities in the oil or gas circuit to stop them from invading the system interior and causing malfunction; various filter elements should be replaced regularly in accordance with the requirements of the (operation and maintenance manual); when replacing the filter element, check whether there is metal attached to the old filter element, if metal particles are found, promptly diagnose and take improvement measures; use the pure filter element that meets the machine regulations. The filtering capacity of the counterfeit cartridge is poor, and the quality of the material on the face of its filter layer will seriously affect the normal use of the machine if it does not meet the requirements.
5. 5.Daily maintenance; check, clean or replace the air filter element; clean the interior of the cooling system; check and tighten the track plate bolts; check and adjust the track counter tension; check the air intake heater; replace the bucket teeth; adjust the bucket gap; check the front window cleaning fluid level; check and adjust the air conditioner; clean the floor inside the cab; replace the crusher filter element (optional). When cleaning the inside of the cooling system, wait until the engine is fully cooled, then slowly loosen the water injection cap to release the pressure inside the tank before releasing the water; don’t do the cleaning work when the engine is working, the high-speed rotating fan will cause danger; when cleaning or replacing the coolant, the machine should be parked on the horizontal ground.
6. 6.Every 250H maintenance items. Check the oil level in the final drive box (add gear oil); check the battery electrolyte; replace the oil in the engine oil sump and replace the engine filter; lubricate the slewing ring (2 places); check the tension of the fan belt and check the tension of the air conditioning compressor belt and make adjustments.

These 6 suggestions on how to maintain your excavator will hopefully help you.
