Warning:

1. Before fill ing fuel int o tank , you 'd bett er st op the engi ne; Sm oking is no t all owed durin g

fuel filling and check & repair for fuel system.

2. In no case can gasoline or alcohol be filled in diesel oil. This mixture can lead to fire or exp losion b ecause it is m ore deto nable than pu r e g as o l i ne in fuel tank. Differen t gr ade oil can't be mixed for use.

●

Important:

1. Only very clear fuel can be used. Fuel should be precipitated for above 48 hours and then only the middle and top fuel can be filled into the tank with a filter. No full fuel for volatilization and screw down the tank cover after filling.

2. Fill fuel before the tank is empty. To fill fuel after the oil is used out in the supplying system, air must b e exha usted from th e supply ing system firstl y.

3. Do use a clean filling tool. Don t wash or wipe with diesel oil. Wipe the overflowed diesel oil at once.

4. Wash fuel tank regularly, discharge precipitated oil, and wash diesel oil filter.

’

5. Don t use open oil drum to transport fuel.

6. Put all cloth with oil into containers with covers. No dog-end can touch it.

’

7. You d better check the engine oil on each lubricated site very often. Fill oil at the sites in time. Fill grease into grease nipples regularly.

4.2 Wate r

4.2.1 Only clear and soft water can be filled into water cooling tank to avoid inefficient

performance caused by scale incrustation.

4.2.2 Hard water(in well, spring and so on) should be softened and then be used. Follow the steps below to soften the hard water:

1. Boil up hard water, precipitate and filter it.

2. Use causti c soda to tre at har d wat er at a rate of 1.5g/ l

Working in cold areas, anti-icing fluid can be used for cooling water.

Attention:

When the engine works or just after it is stopped, the water tank has a high temperature, so it is dan gerous to open the t ank cover a t that time. Only after the tank is c ooled down can it b e opened. To open it , you can loose the cover first to release its inside air pressure.

●

Important:

1. Dirt should be eliminated from radiating water tank to guarantee its heat radiating performance. When the water tank is too hot, you can't water the engine or the tank to avoid breaking the tank. You should reduc e its l oad an d onl y aft er th e water is not so h ot can cooli ng water be filled with the e ngin e runnin g. Ch eck cooli n g w ater in t h e tank that shoul d be kept ful l. C o oling wate r can t be less th an 2/3 of the tank volume.

2. When the water in tank is over 100 , stop the engine immediately. Have a necessary check and repair on the water tank after it is cooled.

3. When op erat ion in th e col d ar ea wi th a t em perat ure unde r 0 is o ver , you sho uld d isc harge all the water with tractor idling.
