Section 2. Operation and security requirements of engine
1, Fuel, lube Oil and Cooling water
1. Fuel. Users can choose diesel adopted according to local ambient temperature. In
China, we choose according to GB252 light diesel. In summer adopt No.”0” light
diesel, in winter adopt No.”10” light diesel.
The diesel must be a long time precipitation
before inject into tank (not less than 48h). During refueling should us cloth filters. Thus
can extended fuel pump and injector life.
2. Oil. In China generally adopt according to GB11122 Diesel Oil. In summer adopt
No.CC40 diesel oil; in winter adopt No.30 diesel oil, used CD class diesel oil for turbo
diesel engine. Must filter through strainer when inject in to diesel engine.
3. Coolant. Applications of rainwater, tap water or clean water are suitable. The water
wells for water or well water should not be used. If the water contains more minerals,
diesel engine cooling water system will have more scale, easy to cause failure.
Therefore, If you want to use wells, springs and other water sources, must be
softening. There are two ways to soften: (1) boiled (2) in 30 liters of water to add 20
grams of caustic soda (caustic soda), made solution. Can add antifreeze in cold winter.
Ant freezing Fluid is the most commonly used public glycol (TEG) aqueous or alcohol.
Diesel difficult to start in low temperature, cooling water can be heated to 80 °C to use.

Preparation before starting
1, Check if the joints that fix the diesel engine are reliable and if the operating handle
is flexible.
2, Rotate the crank for several times to check if the moving parts are flexible and if
there is any obstacle.
3, Check if the oil surfaces inside the oil sump and injection pump are within
regulated scale range, and if the oil tank is full and if the fule loop is smooth.
4, Turn on the fuel tank valve to check if there is are inside the loop, if yes; loosen the
