Filter manufacturers to explain the contents of the regular maintenance of fuel filter 1 250 hours after the new machine should replace the fuel filter and additional fuel filter; check the engine valve clearance.
2 routine maintenance; inspection, cleaning or replacement of air filter elements; cleaning of cooling system internal; inspection and tightening of track shoe bolts; inspection and adjustment of track reverse tension; inspection of intake air heater; replacement of teeth; adjustment of bucket clearance; Window cleaning liquid level; check and adjust air conditioning; clean the cab floor; replace the crusher filter (option). When cleaning the inside of the cooling system, after the engine is sufficiently cooled, slowly loosen the water inlet cover to release the internal pressure of the water tank before draining water. Do not perform cleaning work while the engine is working. High-speed rotating fans may cause danger. When cleaning or replacing cooling In the case of liquid, the machine should be parked on a level ground; the coolant and anti-corrosion devices should be replaced in accordance with certain standards, and the ratio of antifreeze to water should also comply with certain requirements.

Check the oil level in the final gearbox (add gear oil); check the battery electrolyte; replace the oil in the engine oil pan, replace the engine filter; lubricate the slewing ring (2 places); check the tightness of the fan belt and check Air conditioner compressor belt tension, and make adjustments.
6 maintenance items every 500h. At the same time every 100 and 250h maintenance items; replace the fuel filter; check the height of the slewing pinion grease (grease); check and clean radiator fins, oil cooler fins and cryogenic radiator fins; replace hydraulic oil Filter element; replace the oil in the final gearbox (only for the first time at 500h, 1000h later); clean the air filter inside and outside the air-conditioner system; replace the hydraulic oil vent filter element.
7 maintenance items per 1000h. Simultaneously with every 100, 250, and 500h maintenance items; replace the oil in the slewing gear box; check the oil level of the damper housing (return oil); check all the turbocharger fasteners; check the turbocharger rotor Clearance; inspection and replacement of generator belt tension; replacement of anti-corrosion filter elements; replacement of oil in the final transmission case.

94000h above maintenance. Increase the inspection of the pump every 4000 hours; increase the hydraulic oil replacement project every 5000 hours.
10 long-term storage. When the machine is stored for a long time, in order to prevent the rust on the cylinder rod of the hydraulic cylinder, the working device should be placed on the ground; after the whole machine is washed and dried, it is stored in the indoor dry environment; if the conditions are limited, it can only be stored outdoors, it should be The machine is parked on a well-drained concrete floor; fill the fuel tank before storage, lubricate each part, replace the hydraulic oil and oil, coat the exposed metal surface of the cylinder rod with a thin layer of butter, and remove the negative terminal of the battery, or Remove the battery and store it separately; add a proper proportion of antifreeze in the cooling water according to the minimum ambient temperature; start the engine once a month and operate the machine to lubricate all moving parts and charge the battery; turn on the air conditioner and cool it for 5-10 minutes.
