Increase the inspection of the water pump every 4000h; increase the replacement of hydraulic oil every 5000h. 2.

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 (back to the oil); check all the fasteners of the turbocharger; check the turbocharger rotor Check and replace the tension of the generator belt; replace the anti-corrosion filter element; replace the oil in the transmission box. Park the machine on a concrete floor with good drainage;

fill up the fuel tank before storing, lubricate all parts, replace the hydraulic oil and engine oil, apply a thin layer of butter on the exposed metal surface of the piston rod of the hydraulic cylinder, and remove the negative terminal of the battery, or Unload the battery and store it separately; add an appropriate proportion of antifreeze to the cooling water according to the lowest ambient temperature; start the engine and operate the machine once a month to lubricate the moving parts and charge the battery at the same time; turn on the air conditioner and run it for 5-10 minutes.
