Went to the near winter maintenance period, many loader in the winter maintenance process often present antifreeze into the oil, the leakage of the radiator and other questions, other before entering the winter replace corresponding diesel and smooth oil is also essential to the. Thus at the start of winter maintenance before fully get all the preparatory work. First, the selection of excellent antifreeze antifreeze measure mainly has two goals: one is the freezing point, the ordinary type antifreeze can be arrived - 40 DEG C, and excellent antifreeze can reach - 60 DEG C left and right sides; second is the boiling point of and antifreeze should at least reach 108 degrees. Anti corrosion and anti rust function is also very important, which is directly related to the life of the equipment cooling system. To consider anti fouling properties. More than 65% of the equipment cooling system scale and rust, has seriously affected the cooling system of heat radiation function and before replacement of antifreeze is the best first radiator in the scale and rust finishing clean again after in antifreeze. Usually antifreeze solution should be changed every year, a year after the anti freezing liquid batch standard has not reached the original maintenance request. Not the same type of antifreeze will not mix, prevent chemical reaction, deposition or onset of bubble. Pump check some of the equipment after the replacement of antifreeze in showing the appearance of antifreeze oil, this is because the water pump seal aging failure, the formation of antifreeze after seal into smooth cavity, eventually reaching the sump. The replacement of antifreeze should be close to the oil level survey. The oil level is increased, should be down to check, usually choose to replace the water pump seal or water pump assembly way. Revised to under no-load operation of the machine idle speed, with new engine oil away into the engine smooth residue system of antifreeze. Note: relationship next replaced the oil gap time. To ensure engine smooth system properly reflect the results. Three, cooling system anti-corrosion filter elements of the cooling system is rich in ion exchange resin, anti-corrosion agent, magnesium plate and other additives, can be useful for the protection of the relevant components. The ion exchange resin can prevent scale structure. The corrosion inhibitor can be formed in the cooling liquid cover to prevent oxidation. Because the magnesium metal active than the iron, the cooling liquid in the corrosive ions and magnesium plate attack reaction, useful to prevent the corrosion of iron. Other filters can filter the anti-corrosion rust, scale and sediment. Anti-corrosion filter must be replaced with the same period of antifreeze, and anti-corrosion filter should be 1000th hours (engine operating time) to replace, to ensure that the anti-corrosion filter to play a useful protective effect. Fourth, fuel oil protection (1) normal selection of fuel to choose according to local temperature and diesel cold filter plugging point and freezing point of diesel. (2) protection fuel oil completely clean oil-water separator: surface clean, check the sewage symbol, timely discharge of impurities, to clean clean should be replaced; cleaning diesel tank: will the bottom sediments to eradicate clean; poor atomization of the fuel injection nozzle replacement; bad checksum operation status of fuel injection pump to ensure normal operation. Fifth, smooth oil selection should be based on local temperature, contact smooth selection suitable lubricant oil solidifying point and pour point and viscosity. The use of high pour point oil can not be smooth at low temperature. On the contrary in the high temperature region is not necessary to use the low pour point oil. Gel point and pour point are smooth and the low temperature fluidity of oil targets, both criterion sex, only method is slightly different. The same smooth oil gel point and pour point are not the same, usually have high pour point 2--3 C pour point. Six and equipment leakage maintenance expansion contraction representation in the hydraulic system, gas, water seals, especially rubber O-ring, rectangular ring sealing member reflect the more significant, temperature to below 0 DEG C, the machine will present oil spills, leaks, leakage phenomenon, especially gas temperature to near 10 degree centigrade. In the equipment to enter the winter before the three leakage of the whole situation to carry out all maintenance, cleaning three leakage problems and dangerous problems. Seven, repair electrical equipment winter equipment aging happens is difficult to start trouble, so before seasonal maintenance check and replace the aging electrical components and wiring is cut to start difficult an essential action, still need to fully view maintenance battery. Heater is winter field operation essential. So before winter should view heater equipment operation status, heating equipment modification. Eight, gas tank check every day drain if tank a few days do not drain, very simple ice blocking in ventilation pipe, the effect of brake system, form a security risk.

A good loader can clearly know how to use the machine, cut down the machine wear, reduce the fuel consumption, and the end of the operation. The following 6 strokes make you become a loader! Come and see. 1, light in the loader heel is tightly abutted control room floor, the soles of the feet and the accelerator pedal to parallel gently underground pressure gas pedal. 2, steady loading machine in operation, the throttle should always hold. Usually operating conditions, the throttle opening at the mercy of the 70~80% is appropriate. 3, from the loader, pedal and brake pedal points out, flat into the control room floor, best not to step on the brake pedal. Loader often in the uneven construction site operations, if the foot is always on the brake pedal, the body will be formed under the control of the operator does not lightly step on the brake pedal.
