(1) Maintenance items every 500h. Carry out every 100 and 250H maintenance items at the same time; replace the fuel filter; check the height of the rotating pinion grease; check and clean the radiator fins, oil cooler fins, and cooling fins; replace the hydraulic oil filter; replace the final drive Oil in the tank (only for the first time at 500h and once in the next 1000h); cleaning the air filter inside and outside the air conditioner system; replacing the hydraulic oil vent filter.
(2) Maintenance items every 1000h. Carry out maintenance items every 100, 250 and 500h at the same time; replace the oil in the slewing mechanism box; check the oil level of the shock absorber housing (return to the oil); check all the fasteners of the turbocharger; check the turbocharger rotor Clearance; check and replace the tension of the motor belt; replace the anti-corrosion filter; replace the oil in the final drive box.
(3) Maintenance items every 2000h. First complete the maintenance items every 100, 250, 500 and 1000h; clean the hydraulic tank filter; clean and check the turbocharger; check the generator and start the motor; check the engine valve clearance (and adjust); check the shock absorber.
(4) Maintenance above 4000h. Increase the inspection of the water pump every 4000h; increase the replacement of hydraulic oil every 5000h.
(5) Long-term storage. When the machine is stored for a long time, in order to prevent the piston of the hydraulic cylinder from rusting, the working device should be placed on the ground; the whole machine should be washed and dried and stored in a dry environment indoors; Park the machine on a well-drained concrete floor; fill the fuel tank before storage, lubricate all parts, replace hydraulic oil and oil, apply a thin layer of butter to the exposed metal surface of the piston rod of the hydraulic cylinder, and remove the negative terminal of the battery. Or remove the battery and store it separately; add an appropriate proportion of antifreeze to the cooling water according to the minimum ambient temperature; start the engine once a month and operate the control machine to lubricate all moving parts and charge the battery at the same time; turn on the air conditioner and run it for 5-10min .
