[Weichai Lovol Class] Winter National Four Excavator/Loader Operation Tips!

November 25, 2022

A cold wave is coming，All parts of the country have entered the low temperature weather.， In order to ensure that the equipment is in an optimal state，Remember to collect the following winter equipment operation tips!~

Do it well“Warm up”Steps

1、After the engine is started，Idle operation required 3-5 minutesProceedWarm up、Allow oil passages and hydraulic components to fill with oil and hydraulic fluid。

（Please choose the genuine oil from the manufacturer.~）

2.If the Vehicle is difficult to start in winter，Each start should not take more than 20 seconds，If it still cannot be started，The start switch should be released，Wait for parking 2-Start again after 5 minutes.。Failure to start for three consecutive times，The cause shall be checked before starting，In case of continuous startup for a long time，Harness may be burned out，Even the battery will be affected by the rapid rise of the electrolyte temperature.“Explosion”。

3.Observe whether the indications of various instruments are within the normal operating range.

Voltmeter:24VNormal range of the car 27.5-29.5V

Water thermometer：Normal operating water temperature 75℃ ~ 95 ℃

Hydraulic oil temperature：Normal operating oil temperature 45 ℃ ~ 85℃

Engine oil pressure gauge：At normal water temperature1.5 ~ 4.5kg

4.Check the connectivity of the Vehicle harness in time in winter.，Especially, the two thick wires on the battery post must be connected reliably.，And there is no corrosion，At the same time, it is necessary to ensure that the battery performance is sufficient and good.，Because it will directly affect the starting speed when starting.。

Other points

1.In extremely cold ambient temperatures，To have a comfortable driving environment，Air conditioning and heating will definitely be used in winter.。

（1）Turn on the warm air coolant switch of each equipment.，Ensure coolant flows into the warm air radiator；

（2）Medium and Excavator/ 'target='_blank' style='color:blue;'>Large Excavators open the instrument air conditioning button to enter the air conditioning interface.，Turn on the air conditioner operation switch，Finally, according to their own needs for temperature.，Adjust the temperature。

（3）The mini Excavator with this air conditioning panel needs to press the heating button.,Enter the heating mode。

2.During the use of the loader in winter，Vehicle starting and oil use are basically the same as excavators.，But you need to pay attention to the braking problem.。

（1）The drain switch of the air reservoir shall drain water frequently.，Especially in the areas with more rain in the south.，It is recommended to drain the water once a day after work.；
（2）Vehicles with Dryer，Replace the Dryer filter element on time.；
（3）Construction site with poor working conditions，The brake fluid shall be maintained and replaced according to the company's regulations.，Prevent contamination of brake fluid、Deterioration，Affect the service braking effect，Causing safety accidents！
