[BONOVO]

1. Clean the body of the small roller inside and out, including the engine, gearbox, hydraulic pump, oil pipe connection and other parts, flush the water tank, oil hydraulic oil radiator, cylinder head radiator and cooling channel, the purpose is to monitor whether there is leakage, which helps to strengthen heat dissipation;

2. Pay attention to whether the bolts of each connection part are complete, loose or lost, such as: engine claw bolts, transmission shaft bolts, gearbox fixing bolts, etc., tighten the loose bolts in time, and make up for the lost ones;

3. List the faults of mechanical equipment in a table and eliminate them one by one. The principle to be followed is from easy to difficult. It is best to use original accessories within the three-guarantee period, which are matched and the quality can be guaranteed. Remember to ensure the quality of maintenance to avoid the same fault. Especially the hidden dangers of safety failures should be discovered and handled in time;

4. Maintain the whole vehicle, grease each lubrication point, replace antifreeze oil, gear oil, hydraulic oil and coolant on time according to the requirements of the instruction manual, and replace the oil filter, diesel filter, hydraulic oil filter, and hydraulic transmission oil filter as required. Some engines have one or two drain switches, and the coolant cannot be drained completely. If water is used normally, the antifreeze must be replaced in winter. Use new antifreeze to force the water out, and then turn off the drain switch. If the engine antifreeze is not replaced, the cylinder block may freeze and crack, causing unnecessary losses.
