How to maintain forklift when changing seasons?

1) Spring curing. Winter goes and spring comes, and the weather is getting warmer and warmer. In spring maintenance, first of all, check the tire pressure comprehensively with reference to the vehicle instruction manual; Add or replace coolant in time, and do not replace it with clean water; Increase the anti-static equipment on the car to prevent the human body from carrying static electricity, and also avoid static interference or breakdown of some electrical equipment on the car; After the car body is covered with dust, don't wipe it with a duster to prevent the dusty duster from causing tiny scratches on the car body; Keep the air filter intact and clean to prevent malicious harassment such as catkins and pollen; Clean the air conditioner condenser radiator and coolant radiator in time to prevent the coolant temperature from being too high due to blockage; Do not turn on the external circulation to prevent dust from being sucked into the air conditioning system; When driving, carefully check whether the hoses of all parts are damaged or aging. If damaged or aging, they must be replaced. Pay attention to check whether the drainage holes on the left and right sides are blocked, so as to avoid poor rainwater drainage and backflow into the car after the rain.

2) Spring and summer maintenance. The weather is changeable at the turn of spring and summer. The key to seasonal maintenance is the selection of lubricating oil and the cleaning and protection of lubricating system; When selecting lubricating oil for EFI vehicles, SJ( 15W-40) or above should be selected as far as possible, and SJ/SL semi-synthetic oil or synthetic oil is most suitable for high-grade vehicles. Clean the inside of the engine without disassembly, and add engine protective agent; In addition to cleaning the dirt and oil stains on the external surfaces of the engine and compressor, it is also necessary to clean the radiator, air conditioning intake network and evaporation box; Thoroughly clean and disinfect the air conditioning ventilation pipes; Check the tires regularly in strict accordance with the air pressure standard specified in the vehicle manual to ensure that the air pressure of the tires is slightly lower and the air pressure of the left and right wheels is the same, and pay attention to check the wear degree of the tires and whether there are nails on the tires, and spray protective agents on the tires regularly; When it gets hot, park your car in the garage and get as much shade as possible. If you park outdoors for a long time, you should cover the car, and it is best to stick an explosion-proof solar film in proportion to the whole car. Before summer, you can give the car a sauna.

3) Summer maintenance. Entering summer, the climate is hot. When maintaining in summer, you must do a good job of heatstroke prevention and cooling to avoid spontaneous combustion of the car; In the case of high temperature for a long time, we should pay attention to the cooling measures of the cooling system; Always check the radiator coolant level, crankcase oil and brake fluid level, electrolyte density and level in the battery, and add and adjust it in time if any abnormality is found; Pay close attention to whether the tire is poorly inflated or measure the tire pressure, and deflate slightly if necessary; After driving for a long time or at high speed in summer, stop to dissipate heat, and it is forbidden to splash water to cool down; In order to prevent the engine from overheating, it should be noted that the fan drive belt should not be stained with engine oil during maintenance to prevent slipping, and the drive belt should be kept as tight as possible; Replace the crankcase and gearbox with summer lubricating oil, regularly check the quantity and quality of lubricating oil and replace it in time; Insisting on using antifreeze made of ethylene glycol and other chemical components can avoid the trouble of "boiling"

4) Alternate maintenance in summer and autumn. Summer and autumn alternate, the weather is getting colder and colder. Seasonal maintenance should start with antifreeze. If you like to use tap water instead of antifreeze in summer, you should replace tap water with antifreeze in time after beginning of autumn; Check the electrode wiring of the battery. If there is green oxide, it must be washed off with boiling water. Carry out a thorough maintenance of the air conditioner, and pay attention to the maintenance of warm air pipes and fans; Pay attention to whether the defrosting outlet under the windshield is normal and whether the heat is enough. If there are problems, solve them in time; When the temperature drops, the air pressure should be supplemented to keep it within the specified air pressure range; Check the wear degree of tire tread. If the tread pattern depth is less than 1.6 mm, please replace the tire with a new one. If the car body has obvious scratches, it should be painted in time; It is best to carry out a beauty maintenance on the surface of the car, from cleaning and polishing to waxing, polishing or coating, and thoroughly disinfect and clean the interior.

5) Autumn maintenance. When autumn comes, the weather gets cold. Autumn maintenance, first of all, we should start with the tire, replenish the air pressure in time to keep it within the specified range, and check whether the tire has scratches; Derusting the chassis, and checking whether there are scratches and screws falling off the chassis; Check the brake system comprehensively, and carry out corresponding cleaning, lubrication, rust removal and other treatments, and check whether the brake is weakened or deviated, and whether the pedal force of the brake pedal has changed. If necessary, clean the pipeline of the whole braking system to ensure the normal performance of the system; Oil, liquid and electricity are important items in daily maintenance of automobiles. Oil, brake fluid and coolant, like the blood of a car, must be replaced at the replacement cycle to ensure smooth oil circulation. Check the cooling liquid, glass cleaning liquid and other liquids to prevent deterioration; Check all kinds of plugs to ensure that the plugs are in normal contact and the waterproof and sealing functions are normal.

6) Maintenance in autumn and winter. Autumn and winter alternate, and the weather gets cold. Seasonal maintenance, mainly based on pre-inspection: check whether there are obvious scratches on the outside of the vehicle, if so, please paint the outside in time; Check whether the engine oil is universal in all seasons. If not, please replace it with oil that is more suitable for winter use. Check whether the oil used in the transmission, transfer case, differential and steering gear is correct; Check whether antifreeze needs to be replaced; Check whether the braking system is normal, check whether the brake fluid is sufficient and the quality is deteriorated, and replenish or replace it in time if necessary; Check whether the brake is weakened or deviated during braking, the pedaling force of the brake pedal and the position of the wheel locking point, and clean up the pipeline part of the whole braking system if necessary; Check the battery connector for looseness and corrosion. If it is loose, please tighten it with a spanner. If it is corroded and alkaline, it can be washed with hot water. Check whether there is anything wrong with the air conditioner. If there is, please repair it in time. Check the air intake, air intake grille, electronic fan and other places for sundries. If yes, please blow it away with compressed air; Check whether the tire has obvious trauma, scratches and whether the tire pressure reaches the standard, and pay attention to regularly cleaning the inclusions in the tire tread; Check whether rubber products such as wiper blades are aging, and replace them if they are aging; Check whether the glass cleaning liquid storage tank is tap water, if it is in that winter, it will freeze and crack the storage tank; After cleaning the interior of the vehicle, nursing with protective agent can make the interior of the vehicle look brand-new

7) Winter maintenance. Autumn comes and winter comes, and the weather is cold. Winter maintenance, first of all, must ensure the smooth flow of oil, institutions must be normalized. Fuel pump, high pressure pump, fuel injection, etc. Meet the requirements; Valves and piston rings are well sealed; Valve clearance and ignition (fuel injection) timing are correct; The cylinder pressure and the tightness of large and small tiles are appropriate; Secondly, make sure that the circuit works normally. The intensity of low-pressure fire and high-pressure fire is appropriate, the damping of high-voltage line, the insulation degree of distributor head and glow plug thermal effect are good, the ignition coil and spark plug work normally, and the starting speed meets the requirements; Select fuel and lubricating oil according to the provisions of the instruction manual, and the ambient temperature and fuel brand should be correctly matched; Take appropriate measures to keep the vehicle warm; In winter car maintenance, you can add fuel system drying and dehydration maintenance agent.

8) Maintenance in winter and spring. Winter and spring alternate, and the temperature is changeable. For seasonal maintenance, comprehensive inspection and maintenance should be carried out in time. First of all, give the car a comprehensive interior cleaning; Secondly, the body paint should be well maintained. In addition, after the cold and snowy winter, the detection of chassis and tires can not be ignored. Because the snow melting agent has a certain corrosive effect, it is necessary to clean the chassis comprehensively. For automobile tires, it is necessary to conduct a comprehensive inspection. In addition, when changing seasons, it is best to change the lubricating oil suitable for seasonal viscosity label. During the seasonal maintenance, the maintenance personnel will make more than 10 routine inspections on your car.

9) Seasonal maintenance focuses on the body and chassis. Peacetime maintenance belongs to "health care maintenance", focusing on inspection, adjustment and health care. It is characterized by "maintenance-oriented" and aims at keeping cars healthy. Seasonal maintenance belongs to "rehabilitation maintenance", which is a comprehensive and systematic detection, adjustment and injury treatment. It is characterized by "treatment-oriented" and aims to restore the health of the car. After a season and a certain mileage, metal parts will wear and corrode, and rubber seals will inevitably age and lose. This deterioration process of quality and performance will develop abnormally with the change of too high or too low temperature. During seasonal maintenance, the focus is on the body and chassis.

10) Four liquids should be paid attention to in seasonal maintenance. The seasonal maintenance of in-use vehicles is generally completed by drivers. The contents of the seasonal maintenance operation center are to replace the lubricating oil and coolant that meet the seasonal temperature requirements, adjust the fuel supply system and charging system, and check the working conditions of the cooling system and heating system. Seasonal maintenance is a comprehensive maintenance of cars. The state of the car should be adjusted according to the seasonal maintenance, and the usual faults should be eliminated in a targeted manner to make the car run smoothly and safely.
