Scientifically determining the interval mileage of various maintenance operations can not only keep the self-feeding mixer in good technical condition, but also save maintenance and repair costs. The maintenance period can be appropriately extended for new vehicles with good technical conditions. For self-feeding mixer with poor technical conditions or poor service conditions, the maintenance period should be appropriately shortened.
1. Daily maintenance content: appearance inspection
Before driving out, look around the mixer truck to see if the lighting device is damaged, whether the car body is tilted, and whether there are oil and water leaks; Check the appearance of tyres; Check the condition of the door, engine compartment cover, handling compartment cover and glass. The signal device checks whether the ignition switch key is turned on (the engine is not started), check the illumination of each alarm lamp and indicator lamp, start the engine and check whether each alarm lamp is normally off and whether the indicator lamp is still on. Check the fuel, check the indication of the fuel gauge and replenish the fuel.
2. Weekly maintenance content: tire pressure
Check and adjust the tire pressure and clean the debris on the tire. Don't forget to check the spare tire. Check the fixing condition of the engine components and check whether there is oil leakage and water leakage on the joint surfaces of the engine; Check and adjust the belt tightness; Check the fixation of pipelines and wires at all parts; Check and replenish the oil; Check and replenish the coolant; Check and replenish the electrolyte; Check and supplement power steering oil; Clean the radiator surface; Replenish windshield washer fluid, etc. Clean the interior and exterior of the car.
3. Monthly maintenance content: external inspection
Patrol the mixer and check the damage of the bulb and lamp cover; Check the fixing of the body trims; Check the condition of the reversing mirror. Check the wear of tires and clean the luggage compartment; When approaching the wear mark of the tire, replace the tire and check whether the tire has bulges, abnormal main wear, aging cracks and hard wounds. Clean and wax the interior of the car; Clean the sundries on the surface of water tank, oil radiator and air conditioner radiator. Check the chassis for oil leakage. If there are traces of oil leakage, check the gear oil quantity of each assembly and make appropriate replenishment, and make sufficient grease replenishment for all oil nozzles of the chassis. Repeat the weekly maintenance content carefully.
4. Semi-annual maintenance content: engine exterior
Clean the exterior of the engine and pay attention to the waterproof treatment of the electrical part during cleaning. If the electrical part has high requirements for waterproof, avoid using high-pressure and high-temperature water guns to wash the engine, and use a brush to dip detergent to clean the engine surface.
5. Annual maintenance content: ignition timing
Check and adjust the ignition timing of the mixer engine, and check and adjust the fuel supply timing of the diesel engine at the repair shop. Valve clearance For engines with ordinary valves, check the high-speed valve clearance. Clean, lubricate and clean the oil dirt on the hinge mechanism of the engine compartment cover, door and luggage compartment, readjust and lubricate the above mechanism.
6. Maintenance content every two years: antifreeze
The service life of antifreeze is generally two years. At that time, the antifreeze should be replaced during the annual maintenance and the cooling system should be cleaned. Due to the hygroscopicity of the brake system, the brake fluid is replaced every two years.
The above is the explanation of the relevant contents from six aspects of the maintenance cycle of the self-feeding mixer. If you have any doubts or needs about this, please come to our website at any time http://www.zkzsljbc.com Consult!
