1、 Chassis engine preheating:

在標準怠速轉速對發動機進行冷機預熱，確保發動機各零部件充分潤滑。

Warm up the engine at the standard idle speed to ensure that all parts of the engine are fully lubricated.

二、制動系統：

2、 Brake system:

及時檢查或更換氣路系統中的空氣干燥器;放掉凝聚在儲氣筒中的水份，防止結冰。

Check or replace the air dryer in the air system in time; drain the water condensed in the air reservoir to prevent icing.

三、冷卻系：

3、 Cooling system:

冷卻系所用的長效防凍防蝕冷卻液能在-20°C(以各類底盤數據為準)下不結冰。如低于-20°C，適當提高冷卻液的濃度，最高濃度不超過60%，避免腐蝕冷卻系統。

The long-term anti freezing and anti-corrosion coolant used in the cooling system can not freeze at - 20 ° C (based on the data of various chassis). If it is lower than - 20 ° C, the concentration of the coolant should be increased appropriately, and the maximum concentration should not exceed 60% to avoid corrosion of the cooling system.

四、蓄電池：

4、 Battery:

定期檢查蓄電池電解液的液面和比重。液面應高于極板10-15mm，比重在1.24g/cm3以上。

Regularly check the level and specific gravity of battery electrolyte. The liquid level should be 10-15mm higher than the plate, and the specific gravity should be above 1.24g/cm3.

每行駛500公里，應檢查蓄電池電極樁與導線連接夾子是否松動、以及蓄電池工況是否正常。

Every 500 km, check whether the connecting clip between the battery electrode post and the wire is loose, and whether the working condition of the battery is normal.

二、液壓系統：

2、 Hydraulic system:

1、預熱：

1. Preheating:

若環境溫度低于液壓油規定的最低溫度時(約10℃)，應對液壓系統預熱，讓發動機在怠速且攪拌筒不轉的情況下，空轉10～15分鐘。

If the ambient temperature is lower than the minimum specified temperature of hydraulic oil (about 10 ℃), the hydraulic system should be preheated, and the engine should be idled for 10-15 minutes without the mixing drum running.

2、北方地區冬天推薦使用H32或L-HM32 (NAS9級)液壓油注意：不同品牌不同型號的液壓油嚴禁混加。需要更換液壓油牌號時，必須對油箱進行徹底清洗，同時清洗或更換濾油器。

2. It is recommended to use H32 or l-hm32 (nas9 grade) hydraulic oil in winter in northern China. Note: it is strictly forbidden to mix hydraulic oil of different brands and models. When the brand of hydraulic oil needs to be changed, the oil tank must be thoroughly cleaned and the oil filter must be cleaned or replaced at the same time.

三、 減速機：

3、 Reducer:

使用GL-5齒輪油，不同粘度等級的油品使用于不同的工作環境四、 供水系統：

GL-5 gear oil is used, and oil of different viscosity grade is used in different working environment

在寒冬季節設備每次使用完畢后，應排盡水箱及管路內的存水，防止結冰。

In the cold winter season, after each use of the equipment, the water in the water tank and pipeline should be drained to prevent freezing.

五、攪拌筒：

5、 Mixing drum:

建議車主們在冬季施工時在攪拌筒上加裝保溫套。

It is suggested that the car owners should install insulation sleeve on the mixing drum during winter construction.
