2. Check, clean or replace the air filter in the digging machine every day; clean the inside of the cooling system; check and tighten the track plate bolts; check and adjust the track reverse tension; check the intake heater; replace the teeth; adjust the bucket clearance Check the front window cleaning liquid level; check, adjust the air conditioning; clean the cab floor; replace the crusher filter (optional). 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 running. 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 must also comply with certain requirements.
3, start the digging machine engine before the inspection project. Check the liquid level position of the coolant (add water); check the engine oil level, add oil; check the fuel level (add fuel); check the hydraulic oil level (plus hydraulic oil); check the air filter is blocked; check the wire; Check if the horn is normal; check the lubrication of the bucket; check the water and sediment in the water separator and daily maintenance of the excavator. Routine maintenance of the excavator.
4, on the digging machine project protection. Boom Cylinder Head Pin; Boom Pin; Boom Cylinder Rod End; Cylinder Cylinder Head Pin; Boom, Stick Link Pin; Cylinder Rod End; Stick Link Pin; Check the oil level in the slewing gear box (add oil); drain water and sediment from the fuel tank.
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; top up with fuel before storage
