The cold wind is blowing，Snowflakes flutter，Winter is really coming.！Winter is also one for our loaders.“Challenge the season”。However， Don't worry ！Next, I will share with you some tips on how to maintain and use loaders in winter.，Let your“Big guy”It can also warm the winter.！

One. Maintain the fuel system，Replace the diesel oil in due time

Winter temperatures below 0.℃ Later ，Diesel viscosity increases，Liquidity becomes poor，It is easy to wax，Poor atomization and combustion，This results in diesel engine startability、Power、Economical decline。In order to make the diesel engine start smoothly in winter,，Diesel fuel with a lower freezing point should be replaced。When diesel is selected，The freezing point shall be 5 ℃ lower than the ambient temperatures℃。

When servicing the engine，Also clean the engine strainer，Replace the fuel filter，Drain and clean the oily water separator。At the same time, check the working condition of the diesel pump.，Eliminate potential problems that could lead to failure。

Two. Check the leakage of hydraulic parts

After entering the winter，Seals for mechanical hydraulic systems，Leakage due to thermal expansion and contraction，In particular there isOA place for a rubber ring.，When the outdoor temperature is continuously below 0℃After，There may be an oil leakage fault.。

Three. Change the engine oil

When winter comes，The viscosity of engine oil used in summer will increase.，Liquidity will get worse，The frictional resistance increases，The rotational resistance of the crankshaft becomes large，Increased wear of piston and cylinder liner，The engine will be difficult to start.，Mechanical power and fuel economy will be greatly reduced，So at this time, we need to replace the winter engine oil with good fluidity.。

When changing engine oil，Be sure to choose high-quality engine oil.。Good engine oil is not easily oxidized at high temperatures.，Does not form deposits in the engine，Can extend the life of the engine。

Four. Maintenance of engine cooling system

01

Check the thermostat

If the engine is often operated at low temperatures，It will cause poor atomization of diesel oil.、Diesel oil drips into cylinder，It will cause the decrease of engine oil viscosity and the increase of engine wear.。So check the working condition of the engine thermostat.，Prevent the engine water temperature from being too low or too high，If necessary, the radiator should be equipped with an anti-freezing device.。

02Replace and add antifreeze

Check that the antifreeze in the engine water tank is below the minimum engraving，The replacement cycle of antifreeze is generally 2 years.，When the antifreeze appears turbid、Deterioration、Foaming and other conditions should be replaced in time.。When replacing the antifreeze，Select a temperature 10 ℃ lower than the minimum temperature in the use area℃，And has anti-freezing function in winter.、Boiling-proof in summer、Anti-corrosion、Long-acting antifreezing liquid for preventing water scaled。When adding antifreeze，Antifreeze of the same type shall be added，Do not mix additions。

Five. MaintenanceBraking system

Check the braking condition。Check whether the brake fails.、Weaken、Deviation，Whether the pedaling force of the brake pedal is normal，And whether the brake does not return.，Adjust if necessary。

Six. MaintenanceElectrical equipment

01

 Engine battery

Check the engine battery terminal wiring，If green oxide is found at the electrode connection，Rinse off with boiling water，Dry the water with compressed air.，Then apply special protective agent，To prevent the oxide layer from reappearing。Charge the engine battery frequently in winter.。In order to prevent the engine battery from freezing due to overcooling and affecting the engine startup，A sandwich incubator can be installed for the engine battery in winter.，Used to increase engine battery temperatures。

02Starter and generator

If your engine has trouble starting in the winter，Frequent starting of the starter shall be avoided。This requires frequent maintenance of the starter，Ensure that all parts of the starter are clean、Dry，Keep good contact between the brush and the commutator。

03Preheating device

Engine with preheating device，The preheating device shall be inspected once before winter.，Keep the preheating unit in good condition。During maintenance, focus on checking the circuit and oil circuit of the engine preheating device.，Avoid the influence on the engine starting performance due to the poor operation of the circuit and oil circuit.。

Once an anomaly is found，Stop the vehicle immediately for inspection。Don't let a small problem become a big one.！

All right，These are the tips for the maintenance and use of loaders in winter.

Hope to be helpful to everyone.！

Remember to be ready for you.“Big guy”Come on、Warm up

Let it accompany you through a warm.、A safe winter！

Good luck with your work.，Have a safe trip！
