3. Check whether there are any cracks and looseness in the working device, the welded joints of the front and rear frames and the fixing bolts;

4. Replace the engine oil, replace the oil filter (it can also be determined according to the working environment and working intensity);

5. Check the tightness and damage of engine fan belt and generator belt;

6. Check and adjust the foot brake and parking brake.

(5) Maintenance at the 500th hour (or three months):

1. Tighten the connecting bolts of the front and rear axles and the frame;

2. The engine oil must be replaced and the oil filter element must be replaced; the transmission oil must be replaced and the filter element replaced; the gear oil must be replaced; the hydraulic oil should be replaced; the filter element of the hydraulic oil tank must be replaced; Depending on the strength);

4. Clean the diesel tank and diesel filter.

(6) Maintenance every 1000 hours (or half a year):

1. Replace the transmission oil, clean the oil filter and oil pan, and replace or clean the copper wire in the breathable cover;

2. Replace the diesel filter of the engine;

3. Test various temperature gauges and pressure gauges;

4. Check the tightening of the engine intake and exhaust pipes;

5. Check the operation of the engine;

6. Replace the filter element of the hydraulic oil tank.

(7) Maintenance every 2000 hours (or one year)

1. Replace gear oil;

2. Replace the hydraulic oil, clean the oil tank and filter screen;
